Had my S3 remapped 3 months ago, since then its been nothing but trouble, have had to replace turbo intake pipe, breather hose left of inlet manifold, breather hoses underside of inlet hose, mass air flow meter. Finally got it running at full boost last night after the inlet breather hoses got replaced.
Can to the car this morning and have no boost at all, turbo is not spooling, it was fine when it got parked up last night. Had a quick look while on route to work this morning but cant see any hoses leaking. Scanned the car and its come up with a DV fault.
Question, If the DV was buggered would that stop it boostng?
How do i tell if the N75 valve is working?
Car is a 225 BAM
