My 2003 318i E46 BMW engine shudders while accelerating from 0km/h upt to 40km/h then it stops as soon as it hits 40k's. Drives beautifully after that and doesn't shudder when in idle. I just had the transmission serviced and head gasket done. HELP PLEASE!!!

SOURCE: Transmission shudder

I had a similar problem on my 93 Accord after I accidentally threw the car in reverse at 50 mph, obviously wrecking the transmission. When I got it rebuilt I was told the transmission pump was to blame (clogged with "shrapnel"). I, and your car manual, recommend taking the car in to get the tranny looked at. Especially considering you just had the fluid changed which is what would normally cause the problems you are describing.

SOURCE: Car shudders when accelerating...

My wife's 02 Audi A4 1,8t had the same problem after talking with Audi (coil pack/spark plugs) we replaced them all and the problem still persisted not to say that won't fix your problem but what I found to be the problem was 3/8 vacuum line (shaped like a S) that comes up on the right hand side between the oil filter and the fire wall that comes from the turbo check valve assembly (its hard to locate and should be done with the engine cool) up to a valve assembly that connects to the intake manifold, what was happening was the hose would become spongy at the bottom (you will have to squeeze the hose from top to bottom to notice the difference) and as the engine heats up it would cause the hose to collapse. Once I replaced the hose and the computer reprogrammed the fuel mixture (about 25 miles of driving) the problem seems to have been correct. Good luck.I had also replaced the turbo check valve about three years ago because of a severe hesitation when you first apply gas (turbo check valve may not be the proper name.) Sorry. Wife Still Loves Her Audi

Bmw 323i e46 making a noise coming somewhere from the engine i think


You will need to provide a little more info before someone can assist - when does it make the noise? All the time, only under acceleration, when turning left, etc? Can you locate it to the front or rear of the engine or to a specific component? There are mechanic stethoscopes that help with this. Can you describe the sound? A squeel, knocking, grinding? Good luck!

1998 Z3.. Manual Trans shudder under acceleration in 2nd gear as it nears 2000 rpms, then goes away as it approaches 2500 rpm's.. Any suggestions?.. Thanks


It could either be the flex disc or drive shaft center bearing. I had the same problem on my 98 Z3 and I replaced both and it took care of the problem.

My 1991 Olds 88, 3.8 litre shudders on even acceleration from a stop or reversing. If you push on the accelerator hard or back off completly, it stops doing it. If your driviving along gliding and you push...


first thing to do would be a transmission service, the filter may be clogging up which reduces the pressure, if that does not work you may be looking at a new torque converter and or pump.

I have a Semi-Automatic 2005 BMW e46 318i. The engine randomly cuts out (stalls) when decellerating, coming to a stop, or when stopped. Other than this problem the car drives fine, and the engine starts up...


The problem you are having sounds suspiciously like the torque converter is not disengaging to allow your engine to spin freely until you are ready to accelerate.If when decelerating or coming to a stop you feel a jerking sensation similar to driving a vehicle with a manual transmission and bringing the vehicle to a stop without depressing the clutch, then the problem you are having is faulty Torque Converter Control Solenoid or a bad Torque Converter itself. If you have any other questions please contact me here. Good luck.
