Need help, Car jerks on acceleration
I have no idea what this could be. When i take off from a stoplight my car starts jerking, loses power, but only in 1st gear or 2nd gear. No lights pop up on the dash. At first i thought it could be the ignition coils going out again, but i just had them replaced abut a month or 2 ago (around 6,000 miles ago). Could the coils be going out already? The jerking happens when im going around 25-30mph, but after i go faster the jerking stops, and the car is smooth. Has anyone had this problem before? Btw i have a 2003 A4 1.8t fwd with 82,000miles. Someone mentioned to me that there could be a leak in the turbo or vacuum? But i don't know much about that.

Acceleration problem ...
i have the same problem in my 1997 A4 1.8L no turbo no nothing just 1.8L. when i accelerate it feels like the cars is dying then it suddenly speeds up and accelerates. i scanned it so many times but nothing!! even on the dash board there are no sensor lights signaling anything!! the rpm is also normal !! and SOMETIMES when i reach speeds 60-80 km/h it feels like the engine is cutting off and on quickly example: like when u run out of gas. And always when i want to to turn the car on i have to press on the gas peddle to start.
PLZ HELP ANY IDEAS??????

I'm not sure if its the same problem as i had butttttt... when i would accelerate around 2-3000 rpms my car would hesitate a bit, kind of like you are saying. I got my timing belt changed, water pump, thermostat etc, everything that goes along with a timing belt change out and i have yet to encounter this problem again. I wouldn't say do something drastic like that first off, but 85,000+ is pushing for a stock TB.

same problem. tons of $$ into new parts..MAP Sensor, coils, plugs, MAFs(3), fuel filter, timing belt, water pump, tensioner, ECT sensor, etc. them turbo went out. time to upgrade for me. maybe this was the problem from the beginning for me. with MAF plugged in i could not get above 3k rpms...with it unplugged it runs (decent) but does not feel like it should. says it boosts to 13psi...and eventually it will drop into safe mode... ran it like that for about 3 months.,.then turbo went bye bye

So i installed the new fuel filter and the problem is still there. Ive also heard that the MAF sensor could use a cleaning, so i took it out and cleaned it. The car has more power but the jerking is still there when accelerating. I can't see any cracks or leaks either. Guess ill be taking it to the dealership and have them look at it.
