    I'm with BMW of North America, LLC (BMW NA). BMW NA is conducting a service action for S54 engines in E46 M3 Coupe/Convertible produced from February 12, 2001 and May 22, 2003. We are in the process of mailing notification letters to affected customers.

    Our ongoing quality testing revealed that the connecting rod bearings installed in certain M3 Coupe/Convertible with S54 engines were not manufactured to BMW quality standards. As a result, the connecting rod bearings are susceptible to overheating and subsequent premature failure if the vehicle is operated at higher engine speeds over an extended timeframe.

    BMW conducted a service action in March 2003 involving S54 engines in M3 Coupe/Convertible. At that time BMW found certain engines experienced premature failure due to contamination of the engine lubricating system during assembly in combination with unfavorable tolerances in the engine oil pump. In addition to the service action, BMW extended the warranty for all internal mechanical engine components that are lubricated by engine oil for a period of 6 years or 100,000 miles, whichever comes first for all model year 2001, 2002, and 2003 BMW’s equipped with S54 engines.

    We sincerely apologize for any inconvenience this issue has caused affected customers. If you have any questions, please contact your authorized BMW center, BMW NA Customer Relations, (800)-831-1117 or send us an email through our website at

    My 2004 M3 SMG convertible is doing this thing where (usually) in 2nd gear it starts jumping/ bucking/ hopping. It is NOT the shifting of the transmission. It is totally bizarre and the dealership keeps lecturing me on the SMG and cannot get it thru their thick heads that it is not the shifting. Has anyone else had this problem????
  • i have the same situation. so, basically it's the SMG A-mode. the only way to avoid bucking is to train yourself to keep constant pressure on the gas while it's reving up from low gears. typically, your foot will natually lift off the gas pedal when:
    1. make a turn
    2. on a bumpy road and you want to slowly pass the bumps.

    the traditional automatic car will simply slow down _smoothly_ after your foot is lift off the gas gradually, but the SMG won't; you will feel like it's shutting down its power all together and immediately a noticeable deacceleration occurs. then, what happens next is that you will hastely put back pressure back on the gas pedal because you think the car is slowing down too much and too unexpectedly and then the car jerks..., which i don't know exactly mechanically why. but all i know is that it's not a unique experience to just me and my M3.

    but over time, i learned to drive smoothly (in A mode) in low gear and be more assertive on my pressure against the gas.
  • The SMG is actually a manual transmission and the behavior you describe is common in a manual car. The engine braking you describe after lifting off of the accelerator is actually considered a positive trait of manuals. I don't remember if the M3 is offered with a true automatic but is seems you would have been happier with a true auto.
  • Clearly, people who have never driven a manual should not be driving an SMG either. Manual transmissions (and I believe the SMG is no different in this respect) do have what's called engine braking as antrey stated. This is a useful feature for those times when you need to slow down slightly, but not enough to apply the brakes. This is great for poor weather driving as a moderate amount of engine braking can assist you in stopping when the roads are slippery. The engine "bucking" and "out of control" aspects occur in all manuals when the engine RPMs are too low. So when you take your foot off the gas, what you should expect is a moderate amount of deceleration followed by 'bucking' if you fail to downshift/apply more gas before you reach the bottom end of the RPM range. ( In my car, a classic manual, this happens around 500-700 RPM )

    I read all the responces to "hpesq's" complaint, and agree in your assessment of a manual gear box and how it responds. However, I know that if you have a clutch to work with, you can eliminate a lot of the bucking and smoothly switch between gears... with the SMG, you don't have a clutch, and therefore might not have that ability for smoother transitions between gears, howbeit the characteristics will be the same if the clutch is left out....I do not own a M3 yet, but have one on order, with SMG...I am not sure now if I am going to like it better, or a strait manual gear box with clutch? Some more feedback on this issue would help me make a more informed decision. Thank You.

    They roll down just fine. When I press the button up (hold the button or 1 push to close all the way) they go up about 5 inches, stop, and go back down about 1 inch. It doesn't matter how low the window was when I first hit the button, if it has to go mere than 5 inches, it stops and reverses. If I try it again it just goes up about an inch and then reverses back down an inch.
    To close it :
    -I pull the window up with you hand and press the button up and it don't stop.
    -I click the button in short bursts, it moves in 1/2 inch increments and it goes all the way up.
    It's a 95 M3 coupe and both windows do it.
    Anybody ever hear of a problem like this?
  • simple2simple2 Posts: 16
    Had the same problem with my 325 cupe.
    I belive this is due to the wear of the power window mechanism.
    I didnot get the chanse to fix it, traded BMW for AUDI.
    After driving A4 for a few years, feel like going back to BMW. I think BMW build bit more solid. Just need to keep it under 10 years old as they start to fail after this age....

    OK, picked up my new M3 with SMG....
    I can now speak from experience, this vehicle is like a dream come true.
    I haven't owned a manual for about 20 years or so. Everything come back a far as what a manual gear box does. You can not stall the SMG. If you don't gear down, it automaticlly switches down to 1st upon stopping. Starting up from stop is a little heasatant, but once the gear clickes in, you take off like a bat-out-of-HELL ! I LOVE this Car !

    I have a problem with my M3 that has only 24,000 miles. "Service engine soon" indicator came on and the dealer proceeded to fix a part in the gas tank. This was a solution that worked only fro a one week. Once I was on the open read and rev-ed up the engine to the higher RMPs the problem repeated itself...

    Any thoughts on this?
    Thanks in advance.

    The light indicates that the on-board diagnostic system-OBDII-has detected and stored a fault. A competent dealer will pull the code and correct the problem. In your case, there may be more than one fault, or perhaps the original problem wasn't properly repaired. In any case, a good dealer or indie shop should be able to solve the problem.
  • dzhdzh Posts: 3
    Thanks... it is fixed but I am not sure if it will hold... you were correct, there was a dual fault. I am hoping they got it right this time.

    Much appreciated.
  • On my SMG 04 M3, after pressing pedal to kickdown button, engine wouldn't go above 4000 RPM. SMG would not shift in Auto, when car is turned off, and restarted, its o.k. until next flooring of the pedal.

    Anyone have this problem ?

    Can anyone give me some info on BMW's rollover protection system? I'm about ten weeks away from buying a 98-99 M3 convertible and I've been doing quite a bit of homework. One of the questions I can't answer is what exactly does the system consist of? I've been all over the internet and can't find it. Is it an option?...What does it do?... Is it effective?... I would also appreciate any insight regarding what to look out for and options I need to find (or should stay away from). I'm a huge BMW lover and my last was a 1984 318, so to me this will be a big step. Thanks to anybody who'll take a minute to respond.

    martyman.. You might have better luck posting your question on the BMW 3-series board.. Since the convertible aspects of your car are the same, whether M3 or not, you'll have a wider readership there, and may get an answer to your question..

    I think the rollover protection consists entirely of hoops that spring out (up) from the rear headrests, and reinforced A-pillars and windshield frame, giving the car a solid frame to keep from crushing the occupants in case of a rollover..

  • I will be looking at a 95 M3 . is there anything I should look for before I have a
    mechanic look at it? He charges $100.. Is this resonable?
  • kyfdxkyfdx Posts: 27,708
    $100 sounds reasonable, but might be wasted, if he doesn't specialize in BMWs..

    This thread doesn't get a very wide readership... You might try posting here:

    BMW 3-series

    Plenty of people that have E36 BMWs there... that might give you some things to look out for..

    If you've never owned a BMW before you MUST have a qualified BMW tech perform the inspection. Next, I'd want to see a full service history. Was the brake fluid changed at least every two years using DOT 4 fluid? Coolant every three-BMW coolant ONLY? Smooth idle? A mechanical over-rev can bend valves. If you don't know, don't go...

    I have a 2001 M3 coupe with 25,000 miles and it is time to replace the rear Continental ContiSportContact rear tires (255/40ZR18). The fronts look like they will last a couple thousand more miles. Tire Rack has them at an attractive price - $139 each - at least compared to the Michelins and Bridgestones. The wear specs shown for the Contis are the lowest at 160 AA for the rear, while most of the others are 220 AA. These tires have produced substantial road noise. I'd like to find tires with better wear and that are quieter, and I realize specs don't always give the best indication of how it will be to live with these tires. I have owned a '95 M3 and a Turbo944 in the past. The 944 had Dunlop D40 M2s that handled well, wore well (>30K miles) and were quiet, but I don't think these aren't made anymore. Does anyone have any recommendations about tires for the M3 coupe?
  • kyfdxkyfdx Posts: 27,708
    You got 25K out of the rear tires on an M3? Wow.. that is fantastic..

    On another note... You can't compare wear ratings across brands... 160 for Continental may be the same as 400 for Michelin (not likely, exaggeration to make a point). I know that is counter-intuitive and illogical, but is fact, nonetheless...

    If you call, ask for Gary... He owns an E36 M3, and really is their resident expert on BMWs...

    I really don't have any suggestions for tires that wear well on an M3... most people are looking for maximum handling on those cars.. I think you did pretty darn well with the Contis....
