I have had my brand new RS3 for just over a week now and put some 500 miles on the clock. The other day I was in some very slow moving stop start traffic and I heard this strange bang/knocking noise, which sounds like backlash from either a CV joint or gearbox, or propshaft, I would just like to add that I have been driving the car with a lot of mechanical sympathy. I can replicate the sound very easy by, accelerating and quickly lifting off the throttle and quickly accelerating again and then you here the bang come backlash. I have come from a new 2017 S3 which didn’t have any noise whatsoever. I wonder if anyone else has heard this on their cars and I have nothing to be concerned with or is it a trip to the dealership. Thanks in advance for any ideas.
