A3 2.0 tdi bkd noises

[dallo]

Have a 2007 a3 2.0 tdi bkd when accelerating under load and go to change gear I here a sound like a dump valve noise coming from somewhere and also when pulling off with some revs on when cold a hear a slight screeching noise from under bonnet.Any ideas looked at other posts but unsuccessful.
Also have a sound like wheel bearing noise at high or very low speed but had the front ones changed about 6 months ago(could this be tyres)
just about had enough of this audi!!

Given that you have a turbo, the noise you describe is probably normal and nothing to worry about..
The screeching is most likely the drive belt in need of replacement, make sure to get the right one depending on whether or not you have AC.
The wheel bearing noise could be a number of things, tyres is certainly one of them, are they in good condition?
What bearings did you have put in, good quality ones? Might be the rears need doing now.

Genuine bearings on the front had all belts done about 18 months ago and again genuine parts.

Could the dump valve noise be the n75 hose?

Has a boy racer had the car before you? Maybe he wanted the car to sound all Nismo like and fitted an aftermarket dump valve.
