10 Saab 9-3 Common Problems


After the success of the Saab 900, and subsequent growth of the company through the late 90′, our favorite car company came out with a completely new car in 2003, as a continuation of the 9-3 name.  Commonly referred to as the Sport Sedan, 9-3ss, or 9440 chassis (as opposed to the outgoing 9400 body style), these cars are coming down pretty sharply in price.  Because of that, like the Saab 9-5, it is possible to buy a fantastic car for pennies on the dollar (we picked up a running 9-3ss for our next race car for $500).  However, like most cars bottoming out in value, it’s important to keep an eye out for a few common Saab 9-3 problems when shopping for your next Saab.

General motors had a heavy hand when managing Saab’s design and building oversight on this project, which means you will see an increased amount of GM parts-bin sourced components.  This is especially noticeable in areas such as switch packs, stereo equipment, and materials used both on the interior, exterior and engine bay.  The chassis is a reworked GM Epsilon platform, roughly shared with a few other GM cars.  In 2007 the interior was updated, and in 2008 the 9-3ss underwent an external facelift, with many newly designed parts added with both.

The 2.0 4 cylinder is a GM Ecotec unit that is also used in tons of other applications.  That’s not to say this is not a Saab engine, as engineers in Sweden had their hands all over it during the design phase.  Additions include the use of Saab’s Ion sensing Trionic system, updated internal materials, block casting processes, valvetrain updates and a revised cylinder head.  This version of Trionic (8 in this case) differs from T5 and T7 because the ion sensing module is a separate unit instead of being built into the direct ignition cassette.  This allows for money saving individual ignition coils instead of a complicated coil pack.  Two turbos were offered, a small Garret GT2052s and a larger TD04 for Arc and Aero models.

Since this run of cars is so comprehensive, and so many changes were made over models, we will focus on the most popular 2003-2007 9-3 with the 2.0 engine.  Many of these will still translate, however there are some differences in later facelifted cars, as well as cars equipped with the V6 engine. So now that you have the rundown of the car itself, here’s a list of common failure points to keep an eye out for when shopping for one of these cars in no particular order.

9-3 Fuel Gauge Reading Empty (Fuel Level Sensor)

Saab 9-3 Fuel Level SenderIt is fairly common to be driving, and witness your fuel gauge suddenly drop to zero.  Although this does not effect the drivability of the car, it can be a fairly annoying problem.  The issue is related to a sensor on the fuel pump which is prone to failure, resulting in a lost signal and an empty fuel reading.  The part in question is attached to the fuel pump, but it is available separately as part number 22672171It fits all 9-3ss models.  However, if your car is past 100k miles on the stock fuel pump, since you have to drop the tank to do the job, we recommend changing the entire fuel pump unit out with a new TI Automotive one, formally known as Walbro.  The fuel pump assembly has the fuel level sensor built in.

9-3 Hesitation, Surging, and Rough Idle (Electronic Throttle Body)

Saab 9-3 Throttle BodyLike nearly all modern cars, the 9-3ss uses an electronic throttle body that is prone to failure.  The throttle body has a rotating ‘butterfly’ plate inside that controls the volume of airflow into the engine, and is controlled electronically via the throttle-by-wire system and the computer inputs.  This means that the computer is in control to more effectively control the engine based on what it thinks you want it to do.  However, when these electronics fail inside the throttle body, latency and tolerances increase in operation causing hesitation, surging, and rough idle.  If you are encountering a rough idle, try cleaning the throttle body before replacing it.  A GM dealer TechII scan tool may be required to calibrate the ETB when replacing.  Don’t forget a new gasket!

9-3 Clicking Noise In Dash (Recirculation Motor)

Saab 9-3 Recirculation Flap MotorBehind the glovebox is a series of motors that control the HVAC system, one of them is the re-circulation flap motor that opens and closes the vent to use outside air.  Inside these little motor assemblies is a series of small plastic gears that have a tendency of loosing more teeth than an aging boxer.  This has two outcomes.  The first is a very annoying clicking sound around the glovebox area.  The second is the flap operation is degraded and you may lose your recirculation feature on your AC.

If this is going on you have two options.  The first is to take apart the assembly, and if you’re lucky the missing teeth will only be on one part of the gear.  You can remove the gear and re-clock it, since only a small section of the gear actually comes in contact with the other gears.  The second option is to simply pop in a new one and be done with it.  We carry the motor in Valeo, which is the OEM supplier of these recirc motors to Saab.

9-3 Binding Steering and Popping Noise From Suspension (Broken Coil Springs)

Saab 9-3 Broken SpringsBroken suspension springs are a common problem in new-gen 9-3’s, and are definitely something to keep an eye out for.  For whatever reason, the springs snap near the perch, causing a knocking/popping noise.  You will notice a definite change in the way the car drives at that point, and you should notice the corner with the broken spring will be sagging lower than the others.  Luckily, it’s an easy to check out problem since a broken spring will be quite obvious upon visual inspection, and easy enough to fix with the right set of tools.  We have a huge variety of 9-3 suspension springs available, so it’s important that if you have a broken spring, to look at the paint markings on the spring.  If they aren’t there, read this post to tell what spring codes you have, or call customer service with a VIN.  If you don’t want to deal with taking the strut assembly apart to replace the spring, we offer complete strut assemblies that we put together ourselves using the best quality OES parts available.

9-3 Coolant Leaks (Water Pump)

Saab 9-3 Water PumpThis is a dreaded failure that most 2.0 4cylinder Ecotec (Saab B207) engines will encounter.  The waterpump is a strange design, driven off a chain in the timing cover rather than on the outside of the engine with a belt.  This seems like it would be more of a robust design, but more often than not you will find yourself having to replace the waterpump without gobs of miles on the odometer.  You can postpone the failure and leakage of the pump by changing the coolant at regular intervals, but generally assume this to be an inevitability.  To change it, you need a special tool to lock the gear in place.  That way you can undo the bolts on the gear and take the pump out on the other side of the bracket.  If for some reason the gear has excessive wear on it, you can buy the Genuine Saab version, which comes with the gear.  We have a quick tutorial on how to go about changing this pump here. http://www.eeuroparts.com/blog/1605/saab-9-3ss-03-water-pump-walkthrough/

9-3 Engine Rattle (Balance Shaft Tensioner)

The broken tensioner and chain guide

Like the water pump, which is tied into the same balance shaft chain drive system, the tensioner that keeps it all running smoothly is almost sure to break, causing an annoying rattle in the engine.  When we were building our Saab 9-3ss race car, both of the engines we were working with had these components snapped and sitting at the bottom of our timing case.  Somehow, both engines ran, and we’ve heard of people complaining about engine rattle for months before either fixing it, or having the entire system come apart (badaboom).

We try to always have a balance shaft kit in stock at all times because of the likelyhood of someone discovering this while having something apart (maybe you dropped a bolt into the case doing a water pump), and requiring this part immediately.  We ship same day, so if your balance shaft chains, tensioner, or guides are messed up, have no fear!  Just follow this link and get everything back up to spec.

9-3 Steering Lock Malfunction – Make A Safe Stop (Ignition Switch Module)

Saab 9-3 Ignition Switch ModuleWhen you see this pop up on your display, it’s not a great feeling.  When I first saw it, I immediately pictured the steeringwheel locking while driving, sending me into some kind of Thelma and Louise style vehicular excursion.  However, this is not the case, and the fix is actually relatively simple.  The most common cause of this message is the ignition switch module, or ISM, located in the center console.  this is the part that you put the key into, and when it goes bad, the body control module doesn’t get the signal it’s looking for, and hence the message will pop up.  Currently hovering around $100, there is a good supply of these switches available, and they are a relatively easy DIY fix (no programming required).  If left too long, you may encounter a no-start situation, so when you start getting this message it’s a good idea to act quick and replace the ISM.  If you are seeing this message and are encountering other weird electrical issues, a fresh car battery may be the solution, as even a slight drop in voltage can cause weird things to happen with the electrical systems of these computerized cars.

9-3 Grinding/Moaning Suspension When Turning The Steering Wheel (Strut Mounts and Bearings)

Saab 9-3 Strut MountAside from being a common wear part on all cars mounted with McPherson struts, the top mounts and bearings in the 9-3ss are particularly susceptible to failure.  When they go bad you will notice an unpleasant grinding noise accompanied by a clunk or squeak when going around corners.  Luckily the parts are inexpensive, and relatively easy to take out yourself.  If your car has over 100k miles on it, you may want to consider just replacing the entire strut assembly, as your struts, springs, bushings etc will all be worn as well.

Saab 9-3 Strut Mount BearingeEuroparts carries the bearings and strut mounts, as well as the entire strut assemblies already put together, so all you have to do is unbolt the old one from the knuckle, remove the three nuts on the top, and swap the assemblies.  Just make sure you are getting the right suspension options before ordering, as there are a few options dealing with sport suspension vs standard packages.  While in there, it’s a good idea to change the sway bar end links as well, since they are inexpensive and must be removed when doing the job anyway.

9-3 Seatbelt Won’t Retract (Seatbelt Tensioner)

Saab 9-3 Seat BeltA saggy seatbelt isn’t just annoying, it’s unsafe.  Saab issued a recall awhile ago (and took their time about fixing it), but lately we have been selling a lot of seatbelt tensioners that pick up the slack in the assembly.  If you have a saggy belt, first check to make sure the belt isn’t binding up near the slot where it comes out of the B-Pillar trim.  If it moves free and clean, something inside the tensioner might be broken, requiring immediate replacement.  We have these in stock to get you back on the road as soon as possible.

9-3 Clutch Pedal Wont Return Up (Helper Spring)

Saab 9-3 Clutch Pedal SpringThis is a common problem that will almost surely manifest itself at some point on all manual transmission cars.  If your clutch pedal isn’t returning back up, relax.  You can still drive the car, it will just feel super weird until you get under there and replace the helper spring and associated clips.  Generally people replace the whole thing (It’s not too expensive), but generally the clip on it is what breaks, and this can be replaced by itself.  We offer both the helper spring and the clip.

9-3 Door Locks Wont Function (Door Locks)

Saab 9-3 Door Lock ActuatorThis one is particularly annoying.  You go to unlock your car, hear it unlock, walk up to pull the handle and PSYCH, that door is still locked.  You look around and notice only 3 of the 4 locks actuated, leaving you to walk around and use the other door to get into the car.  If it’s the driver side door lock, I suspect you will waste no time in replacing it.  Luckily we sell enough of these in Genuine Saab to keep in stock.  Many 9-3ss owners will replace a door lock assembly at some point, so prepare yourself and be happy that these parts are available (and at a good price too!).  Watch out for the VIN split in 2005, as the design changed midway through the year and you must know when your car was produced to get the right lock.

9-3 Key Not Recognized, Haywire Turn Signals, Wipers, Cruise Control, or lost all keys (CIM Module)

Saab CIMThe Central Integrated Module, or CIM, is a very complicated computerized device in the steering column that has a lot of control over your car’s systems.  A few of those systems includes verifying your key chips, controlling your wiper transmission, cruise control, steering angle sensor, as well as housing the clock springs for the turn signals.  If your keys stop working all together (or you lost them), that’s a bad thing, you will probably need a new CIM.  If the other systems listed above are acting super weird, first swap your battery for a new one to make sure everything is getting the right voltage.  If you do this and still have no change, you may be looking to replace the CIM.  The Central Integrated Module requires a dealer program to divorce from and marry to the computer, so don’t start pulling these things apart yourself without a TechII and some training. ALSO, do NOT pull out the red clip, no matter how tempting it is.  If you pull that out without the unit installed in the car and the wheels in the proper direction, you will brick the module and it is not cheap.  We of course will NOT refund sprung CIMs.

9-3 Peeling buttons (Climate Control Button Set)

Saab Peeling ButtonsThe Saab 9-3 is supposed to be an upscale car, but when all the buttons on the climate control panel are peeling and cracking away, it sure doesn’t feel like it.  Luckily these button sets are available in Genuine Saab, and aren’t too complicated to change.  We have two sets, one for cars with heated seats and one for cars without heated seats.  Don’t stare at these any more, spend the little extra on this cosmetic fix and get back to appreciating the interior of your car. Just remember that it may look like the box is filled in packing material, but there is actually 3 loose buttons wrapped up in there, so don’t call us saying that you didn’t get the other buttons, they were in there and we know you threw them away.  Time to start dumpster diving!

I hope that helps, I know I said top 10 problems, but I really came up with 12 since there were some that really did need a shout-out.  Thanks to Ashley in CS for helping out with some of these topics, she is our resident 9-3 expert and has witnessed most of these firsthand.  If you have other common failures that you have witnessed with your 9-3, go ahead and comment below.  Thanks for reading!

    You left out a few other issues that I have encountered over the years such as: Door mounted mirror glass falling off, drivers side taillight plug corrosion, tail light exterior lens becoming unglued and falling off, power amp mounted under drivers seat failure when wet ( snow, spilt drink), rear window exterior trim (black plastic) chipping off, pinch control issues with the windows (fail to stay up). Fortunately I was able to make the repairs myself with parts sourced from eEuroparts.com. Thanks guys

    • Adam Goral

      I have had friends that experienced the taillight socket corrosion, mirror glass falling off (a common problem on nearly all new cars), and pinch control issues. Maybe a part 2 will happen, but for now the list was getting pretty long as it was! Thanks Steve for the comment!

  2. Damien Shulock

    Great list…our 2007 Sport Combi is proving you right. 60k miles = ignition unit malfunction, 70k miles = driver outside mirror glass spontaneous ejection, 90k miles = taillight socket corrosion. About two weeks ago the gas gauge malfunction happened @ 95k miles. I’ll be doing the whole pump&gauge combo. And the peeling interior buttons of course – I’m happy to hear that those are available!

    • Ken S

      The 07s didn’t have issues with buttons. 07 was the year the interior changed and the buttons that peeled were replaced by a GM- like dash. Are you sure it’s an 07?

      • Damien Shulock

        Ken S, I went and checked and you are right, the dash buttons are in terrific shape in our 2007SC. I must have been remembering our 2004 SS Aero when I was picturing flakey buttons.
        Update: did the fuel pump and sender from eeuro (the $225 version) and the job went smoothly. Big awkward parts to work with (cat back exhaust has to come off, drop tank, wrestle with the pump lock ring) but it is a pretty straightforward job. Works great so far.

  3. Damien Shulock

    And how about the Halogen headlight bulbs blowing out prematurely, wiring and plugs melting? Can you retrofit the Saab Xenon headlights in the 9-3’s that came with halogen?

    • Ian

      Hi, We have the headlight wiring problem also. The black wires running to the globe connectors have the insulation cracking and exposing the bare wire. Also going through globes more often than I would expect. Any suggestions would be great.
      Thanks in advance

  4. Steve Koplo

    Excellent data and I’d like to see more of these. I’ve got a 2007 9-3 and am about to get spring/strut assemblies from eeuroparts. The car’s got 153,000 on it and potholes have just done them in. I love the car, which I bought last year, and am an old Saaber from 99’s, 900 and 9000. My only question about the car is why I’m only getting 16 MPG City – is this an ECU problem, O2 Sensor? The car’s been fully maintained on service records.

  5. Joe03SS

    I would add in a couple of more things, leaky seals on HVAC cabin filter housing, front window regulators, wiper transmission failures, and for those of you with 2003’s – secondary air valves. Core engine internals, turbos and ignition on these cars are bulletproof from my experience.
    And forget wonky radio amps below the drivers seat.
    Body holds up great toooo….2003 still going strong after 13 years and 180,000 miles

  6. Anthony P

    I still have my 03 with 243000 mi. On the OD. And I have replaced several of these items. Still one of the best cars I have owned.

  7. Rick

    I have a ’06 SS, 102,000 miles.I have the insulation cracked off, and wires corroded/oxidized, where they go into the headlight bulb plug plastic block. Another one is the rear window regulators (the plastic pulleys inside the track shatter, and the cable turns into one big knot). Also the plastic body of the shark fin antenna, and pieces around the rear windshield falling out.

    Would pulling the trim around rear windshield out, and filling in the gap with black RTV/silicone/Poly.Ur, or window weld, be a viable repair?

  8. Leonel

    I have a dodgy power steering and read on some forums that even after replacing it, the problem sometimes persists. I was under the impression that power steering was a common problem, but not according to this?
    The cost of replacing with the risk of failing makes me wonder of disposing of the car instead (190k).
    Your advice would be precious. I probably should call you for a quote as the turbo gasket is also leaking, leading to contaminating my heating with toxic fumes…
    Its a shame as this TID has a nice powerful drive and interior trim and I feel as being a shame to send it to junk.

  9. GRAHAM

    HEY GUYS. I PUT ONE OF THE 22672171 LEVEL SENSORS IN MY TANK, NOW IT READS BACK TO FRONT. I LIVE IN AUSTRALIA, GOT THE PART FROM EEUROS. WHAT IS THE G O WITH THIS?

    • Adam Goral

      Australia huh? Your solution is to simply drive north of the equator and it should read right ways up once you get into the northern hemisphere. Just kidding! Since you are in a foreign market (where the cars that are produced are quite different in a lot of different ways), it is possible that the US/Canada model part is different from the Aussie spec sender. We do not have access to foreign market dealer software due to a variety of licensing reasons, so we can’t say for sure. I took a look at the sender and it looks like you could potentially take the arm off and flip the board. I attached photos to give you an idea of what I’m talking about. That might keep you from having to do an international RMA and potentially getting a replacement with the same issue. Saab 9-3 Fuel Sender 1 Saab 9-3 Fuel Sender Example 2

  10. Aaron

    Don’t forget the windshield washer jets coming apart from the bottom and leaking. Outside ambient sensor failing, ignition coils failing, information display knob being erratic and intermittent misfires at idle. Other than that I love my 06 9320T.

    PS. There’s now a recall for driver’s airbag.

    • Adam Goral

      Thanks Aaron, we were trying to keep it under the 10 most common problems, the comment section is a great place to list additional issues because we all know….there will always be more than 10!

  11. mike Nolan

    I think they missed two things. The electrical connectors in the back for a 9-3 melt and require repair. the other is the head lights need replacement a lot more often then most other cars I have owned.

    • MDev

      Ive had my ’99 9-3 for a year, and have had to replace headlight 3 times, and had 3 batteries test as “bad.” However, it runs great and is the only maintenance I have had. My decision to invest $1,800. in a 18 yr. old SAAB, in lieu of a monrhly car payment, has paid off! How long do they live?

  12. Nigel Edlin

    Hi to all you Saab 93 enthusiasts, I have just purchased a lovely 09 sportcombi here in New Zealand with 71500klms on the clock . I am interested in this forum as I need to be aware as to what problems may arise with this lovely car, which I might add is a pleasure to drive. (my wifes new drive). Keep the information coming its very helpful, a little scary but helpful.

  13. Nigel Edlin

    Hi further to my last post I am keen to learn as to why the exhaust on our Saab are black rather than say grey and what would be required if one was to have the vehicle tuned for optimum performance(fuel wise). Also at 71.5klm should I have the radiator flushed to forstall the inevitable problem with the water pump. Were major improvements made to the 2008-9 model over and above the 2006-7? Any advice would be most appreciated, cheers Nigel Edlin.

  14. TimmyTwoPants

    2003 93 Arc in upstate NY USA, 63k miles only have had the broken spring one. One other for me was – I’m told I shut doors too hard(lol?), and had a problem with lock and mirror controls on left side. Watch tut on taking off door panel and found right there a hanging connector that had worked itself apart.

  15. David Haase

    Regarding popping sound in suspension, Mine is a 2002 93 Hatchback with about 184000 miles on it.
    Visual inspection did not reveal broken spring. Most recent event happened while backing very slowly out of parking stall with steering set to full right. After the event there was no noticeable difference in the handling of the car.
    Plan is to inspect again and if nothing found with springs focus on the struts.

  16. Rob Jackson

    Popping noise in front end replace the strut to stabilizer links before spending big money. My 2007
    Saab 9-3 Conv sounded like everything was about to fall out going over bumps. The Moog links
    have grease fittings and appear like they will last. If you can remove the front wheels you can
    install these links in no time.yourself. Replace these links which will run approx $100 + or – for 2 quality
    links. If that doesn’t help then spend $ for everything else. Replace these 2 links first.

    • Adam Goral

      There isn’t a specific fuel filter on these cars. There is a debris sock on the fuel pump but due to the cleanliness of modern gasoline distribution infrastructure and the plastic fuel tank, Saab must have decided not to include a specifically replaceable one (this is my own theory). With no more metal fuel tanks or gas station tanks, there generally is much less to filter.

      • James Respaut

        The ‘sock’ is just the inlet filter before the pump. There is a real filter after the pump but it is also part of the whole fuel pump assembly. Follow the lines, one of those cylindrical assemblies in the top cover is the filter.

  17. Robert Ho

    Has anyone experienced persistent CEL problems goes away comes back? Diag codes say misfirings. I replaced ignition coils, and spark plugs. Mechanic says dirty fuel lines, so they did BG44 and I dumped Seafoam as well. Still have issues. HELP!

    • Adam Goral

      A common reason for misfires that aren’t ignition coils or spark plugs is air leaks. Check all the hoses and clamps from the turbo to the intercooler as well as looking out for broken vacuum hoses or fittings on the intake manifold.

  18. Jeff Hahne

    My problem is both front power seats have play in them where they’ll move front and back when braking and accelerating. A new seat track costs over $4,000 yet it’s probably one one bad component that fails. But I can’t find any information online about what that part is likely to be.

    • Adam Goral

      I think the best approach to this is to take the seat out and have a look. They aren’t complicated, and are only held in with four fasteners. On the sub-hour journey of uninstallation, I’m sure you will come across what is causing your looseness. I am curious as to where that $4000 number came from, we show a seat rail for about 90% less. Recycled parts may be your best bet, you will probably be able to find an obscure part like that seat rail for about 1% of that $4000 price. Hope that helps, good luck.

      • Jeff Hahne

        The problem is any used seat rail is likely to have the same issue so didn’t consider that route. My mechanic placed long life washers where the play was happening as the old ones had disintegrated. Due to the labor involved it was still a costly repair.

    • Rbroc

      The cabin air filter housing has a crappy foam seal that lets water in from outside. Remove the housing, clean the surfaces with rubbing alcohol, reseal with silicone caulk. Retest with a pitcher of water poured down the rt side of the windshield. The water may have killed your blower motor too. If not , check the A/c drain on your evaporator to ensure its not clogged.

  19. Stucandu

    Heated seats not working.
    Had a 9-3SS, never worked.
    Sold it, got a 9-3 convertible and they worked…the first year.
    Come the second winter…nada.
    What’s the deal?

    • Adam Goral

      Many times the elements get broken due to wear, because they are thin and fragile. The most common problem is due to people kneeling on the seats at some point to grab something in the cabin. This puts a small zone of high pressure on the heating element and stretches/breaks it.

  20. Abdul

    I have a 2007 Cadillac BLS which has the ame motor as the SAAB. The msg I amgetting now is “coolant level low” , but the coolant is full. What could be the problem? I live in South Africa

    • Adam Goral

      Very interesting, I’ve never heard of a BLS before. There is a sensor in the coolant reservoir that senses the amount of coolant on many cars. Most likely the sensor is gummed up, stuck, or just bad. You can either replace the sensor, the reservoir with sensor, or attempt to clean it.

  21. Jasen

    Hello Saab model 93 year02 engine 2000cc manual is facing a proble. After 15minutes drives it switch off and dont get on immediately.

  22. John Jenney

    I have a 2003 93 Turbo convertible. Recently (8 weeks ago) Idler puller came apart and belt was destroyed. Before I got to a place where I could stop the car it had pegged the temp gauge. I had it towed home, replaced pulley and belt and it worked fine, idled perfect no overheating problems. This past week it kind of stuttered a couple times on the road. Three days ago it took a couple minutes of cranking to start. Never been a problem before. Yesterday after i got home I shut it of, all normal. Later, about an hour, it would not start. Today it just cranks and cranks but will not start. A year ago I replaced fuel pump and crank sensor. Fuel pump activates when the key is turned on. Could the heat from the day the belt broke have damaged the coil cassette? any suggestions??

    • Adam Goral

      Do you have any check engine lights on? Look for the signs of a headgasket going, oil in the coolant or coolant in the oil. It might be a good idea to do a compression test while you’re at it to rule that out.

  23. John Jenney

    My 2003 93 Turbo convertible broke the drive belt, and before I could get to a place to stop it heated to the max. Shortly after, my ignition cassette failed. New cassette and plugs and it ran fine again. However. since then the turbo guage is in the mid white range at starting, and on almost acceleration it goes slightly into the yellow. If i hit the pedal hard, the gauge goes to the edge of red sometimes slightly into the red. It runs cool, performs about as normal, no warning lights on at all. The turbo is quiet but i’m wondering why the gauge is acting this way. Before the heating problem, it was much lower in the white zone. When driving, when I back off the gas the needle goes to the bottom of white, but when I stop and idle its about Midway. Component problem, or am I just being overly concerned??? Thanks for any assistance at all.

    • Adam Goral

      Hi John, the turbo gauge in a T7 car (not the model of this article but hopefully I can still help) is based on the amount of reference vacuum. It’s more of an engine load gauge than a turbo gauge in that respect. Make sure that all the vacuum hoses are in good shape and nothing got messed up in the debacle.

  24. Chaz T Briggs

    I’m have problems find a knock sensor for my 2006 9-3 v4 2.0t. I keep finding one for the v6 do anyone know if it’s the same fit?

    • Adam Goral

      The electronic ignition and injection use something that’s called an ionization unit to optimize burn and decrease knock without a knock sensor. If you are looking at generic codes, most likely you need to replace the ionization module, since there is no knock sensor on your engine.

  25. 安娜

    Check all the hoses and clamps from the turbo to the intercooler as well as looking out for broken vacuum hoses or fittings on the intake manifold.

  26. Paul V Moodie

    Saab 93 2.0 2006 common problem: temp gauge sticks when ignition is off and then goes ‘off the scale’ when on agaib (although actual engine temp is fine) – quick fix is to disconnect battery, I know, but this keeps recurring.
    Any permanent solution?

  27. Des

    You guys are great!!! Keep the information coming. Saab’s are great cars. Great forum for do it yourselfers. Thanks a million.

  28. Desmond Levy

    I get a rattling sound from under the hood only when my AC is on. Sounds like it’s coming from the engine. As soon as I turn of the AC it stops. Hard to tell here it is coming from when I check under the hood. Will check my pully first.

    • Adam Goral

      A pulley, specifically the tensioner, is put under extra stress when the AC compressor clutch engages. If it’s loose and not able to keep tension, it’ll rattle back and forth potentially causing your issue.

  29. Aaron

    Thanks for the article! I recently replaced the head, head gasket, timing/balance chain, water pump, and thermostat. It all started with a grinding noise on the timing side of the engine (bad balance chain tensioner, broken guides) and led to replacing original parts while I had everything apart.
