I am running what appears to be a factory setup!! Key word is appears... I have only had the car for two weeks and after running ok for those two weeks it seems to lose boost...well it does lose boost sometimes. This is intermitent though as I said. Sometimes I will get full boost while others I will get none or hardly any!! Any ideas?? New to Audi's.

I had same problem and solved it yesterday, thought the boost valve regulator was faulty, after replacing it still there was a boost problem, checked it out again and found after looking at the 2 wires we found 1 was broken. Soldered and put old valve back on and car is now fine :-)
