When im driving my 2.0tdi bKD audi a3 and i release the accelerator under 2200 revs to either change gear or brake i get a huge dump valve sort of noise i have checked all my boost hoses and tightened them, i have so oil in the hoses due to fitting catch can plus i had a smoke test done and found no leaks at all the car is pulling perfectly fine and dyno results went up after exhaust bedded in its now running 181 bhp with 309ft lb torque, the car drives perfectly no problems or lag etc etc, just the noise its just worrying me ive been told it could be the EGR being faulty not the hose under it i mean the actual EGR meccanism is this a possiblity ?
Also has anyone else got this problem and could you shed some loght on it as i dont want the car to be running faulty as vcds detect nothing and ive done everything i can
thanks
