I had some issues with my Turbo on my 04 8P 2.0 TDI where it was going into limp mode now and again.
I took it back to the garage i bought it off, as it was still under warranty, and they said a hose had come off (perished). so they replaced it and I it seemed fine and then it started happening again.
This time I took it back again and they told me the wastegate valve and something else was damaged so bought a refurbed turbo and fitted it.
All appeared to be fine and dandy (car felt excellent compared to before!) and then it happened again! I took it back and basically said if they don't talk to Audi about it and get it properly sorted out I didnt want the car back.. rah rah etc.
This time round they realised that a meter (can't remember the name now but in relation to the turbo wasn't working also so ordered in a new one and some new seals and fitted them.... "sigh"
The car has been going great the last few days and I think it's all sorted now but I had a quick look on the net about anything I should be doing after replacing a turbo and there are a few things mentioned like changing the oil etc.
Anything you guys think I should be doing after this part replacement???
I was also given a purple Skoda Octavia Estate as a courtesy car which the guys at work named "The Purple Hornet" but hopefully that part of my life is over now....
