Car trembles during takeoff

I am driving 320i 2004 Model, my car doesn’t have a smooth take off. When I release clutch the car trembles, even if I release the clutch slightly without engaging accelerator.This cause me to takeoff very slowly to reduce the trembling or if i try to takeoff normal balancing the clutch and accelarator the car will tremble jag and go off. It does these only when I take off. I took the car to the workshop to be inspected and the mechanic concluded that I should change my clutch. All the deferential bushing is still ok. So my problem is I am not convinced that the cause of this vibration is clutch. Anyone with any ideas please.

Does the clutch slip under load ? Do you know how to test it ?

drive with a speed of 40mph on 4th gear and kick the throttle all the way down, if the RPM rises and the car does not accelerate, ur clutch is slipping. if the car accelerates slowly and the RPM is steady, ur clutch is ok. did u check all the mounts?

If the clutch does not slip, it probably does not need replacing. Find a better mechanic.

Nothing yet, I was advised about a clutch tweak but only to find out that my car does not have a clutch switch. I am still battling with the irritating trumble during every take-off

Might be Guibo

Might be contaminated clutch, or bad pressure plate springs.

Might be either Guibo, as GFF mentioned, or drive shaft center bearing. Those seem to be the cause of 80% of these problems. Check the driveshaft U joints while you are in there.

Car trembles during takeoff

I would agree with the contamination theory. I periodically experience the same problem, and I find stop and go driving makes it worse. I fix it by occasionally bedding my clutch, similar in concept to bedding brakes. On a long, empty road, I'll start in 2nd or 3rd gear, revving the engine pretty hard up and down while slipping the clutch. I do not let the clutch fully engage. I'll do this for maybe 10 seconds, then push in the pedal, put the trans in neutral and coast to a stop. I'll leave the pedal depressed for at least 2 minutes to allow the clutch and flywheel to cool before letting the pedal out. The theory is that by heating up the mating surfaces I'm burning off contamination and depositing a smooth layer of clutch material on the flywheel. Of course, I accept no responsibility if you try this and toast your clutch. Good luck.
