Hi new to the forum, been reading in the background for a while. Helped me fix my rear washer wiper motor
A3 2.0tdi 57 plate
When driving in heavy traffic if I pull forward then take out of gear to free roll to car in front. The engine seems like it's going to stall gets a low down knock. As if being starved of fuel or air. Can make it happen on demand hot or cold car. It only does this for about 5-10 seconds before normal engine running noises again. Due to this I have had a play with revving the car to see if anything changes and one thing I have noticed. If free wheeling out of gear and give it a little rev, the revs go up but on taking foot of pedal the revs go up a little further before coming back down. Not sure if related. Normally when rev car, I take foot of peddle revs drop straight away.
I have changed the following anyway when bought car, air filter, fuel filter, oil filter, oil, took egr valve off cleaned and refit with new seals, took maf off cleaned and refit.
As for clutch when car is cold if half pressed I do hear a mesh type spinning noise. Only when holding at half biting point. When car is warm this disappears. No clutch slip when delivering power.
Car drives great, just don't want anything to be happening that I should be fixing, before it breaks.
