#4 of 228 Re: M3 out of control [hpesq] by dietcoke1 Nov 08, 2004 (2:00 am)
Replying to: hpesq (Nov 02, 2004 12:06 am) 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.
#5 of 228 SMG bucking by antrey Feb 14, 2005 (11:41 am)
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.

Replying to: hpesq (Nov 02, 2004 12:06 am) 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 )   HTH Replies to this message: jkaytor (Mar 30, 2005 8:45 pm)

Replying to: hypnotoad (Mar 25, 2005 10:11 am) 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.
#8 of 228 Power windows won't roll up on 95 M3 by 95m3a May 10, 2005 (3:16 pm)
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? Thanks, Stevan Replies to this message: simple2 (May 19, 2005 8:04 pm)

Replying to: 95m3a (May 10, 2005 3:16 pm) 95m3a 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....
#10 of 228 SMG- Manual Gear Box by jkaytor Jun 16, 2005 (6:59 am)
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.   DZ

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.

Replying to: div2 (Jun 17, 2005 10:33 am) 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.
