    need some help or advice with regards to my pain in the **** A4 1.8t. so far this month the car has had a new clutch and complete steering rack now im having probs with boost! Couple of weeks ago my temp gauge decided it didnt want to ever move above quater so i was recommended to repalce the temp sensor switch which has been done and ecu cleared at vw, worked for couple of days then went back to just quater, so i had the thermostate unit changed, since then gauge has worked fine but now some days car boosts fine and others it wont go above 5psi, seems to tie in with how hot the engine is running, when cold it boosts to 7-8psi and when hot wont move. im backed in to a corner now and hoping there is a 4 ringed angel out there!!
