I have a serious problem with my 6 speed in first and second gear (usually in sport mode). When in gear, car jerks and bucks so severely, it almost feels as if the car is being held back. People who have driven with me when it occurs can not believe the extent. I have taken the car to the dealer many times for them to say the have been unable to find anything wrong. Within the last two weeks I went out on a test drive with the head technician, who certainly experienced what I have been dealing with for the last year. He said he has only seen this happen once or twice before. Just yesterday they had an engineer from BMW drive the car and claimed this was normal. It is absolutely impossible for this to be true, and based on what the tech. said I think he was only trying to cover his product. Has anyone ever heard of this before, and if so any recommendations? Desperately seeking the truth, Thanks!

IMO, it is a difficult manual tranny to drive. If you don't launch correctly, you feel like you're riding a bucking bronco. Were you in the car when the tech drove it? If so, was he able to drive smoothly?

How many miles on the car/clutch? As the clutch breaks in, it does become more forgiving.

I absolutely agree with Gabe, the M3 drive-by-wire system does takes some getting used to and could be the cause of the bucking.

Both my e30 and e34, all other E30's I test drive, the Z4 2.5i my friend's dad owns (he's a master mechanic at the local dealer [hihi]), and my friend's e36 does EXACTLY what you are describing... I think it's the nature of the transmissions or the gearing. It makes the cars very difficult to drive in stop and go traffic/parking lots w/out looking stupid or having a nice bouncy ride.

This isn't to say there is nothing wrong with it, but you can't drive the car under idle RPM's, and every bmw I've driven, the slowest you can go with the clutch out is about 5 mph at idle speeds. I still believe it's just the nature of the car and how it's driven.

As everyone says, this is a the nature of the car. I had the same trouble when i first got it last yr, and have gotten much better. I think what happens is you press the gas, the car has such a quick acceleration, that instinctivly you let your foot ease up, then you mentally realize you want to continue to go , so you press the gas again, etc. I foud the trick is to really concentrate, mentally prepare for the acceleration you will feel, dont punch it neccesarilt, just be consistent with your foot,

Now about th eonly time this happens to be is when i am coming home from the gym, and my leg is sorta sore, and harder to control. Also i think as someone else stated, the clutch gets smoother.

good luck

Yeah, I've experienced the same phenomenon in the two BMW manuals I've driven. My E30 can be pretty difficult to drive in stop and go traffic. The only way to drive it smoothly in stop and go traffic jam type traffic is to excessively slip the clutch [mad]. The 2000 Z3 2.3i I drove also had similar behavior, but it was a little smoother than my E30 is.

I didn't think it was just me since I can drive my dad's S10 pickup stickshift ultra-smoothly, and if you can drive that damn thing, you can drive anyting.

I have been driving manuals since my first new car - a 1970 VW Beetle. (shows my age) I have a 2005 325 and it has been the toughest manual to get used to in 1st and from 1st to second. I have heard tha an M3 is even tougher to get uset to. It took a while but now things are pretty smooth. Every once in a while, however, I still bounce the car.

I have a 2004 M3, and have the same problem. Never had it with my prior car, a 540i 6 speed. It happens more with sport engaged, and over bumpy pavement! I have to be very careful, especially with others in the car...
