hi to all, just got my self a S3 ,great car with full audi service history . recently had a revo trail map and since then the turbo has been whinning or whistling when i put my foot to the floor ,verry loudly. but not if i drive it gently or half power. there is no white smoke & no faults on VAG-COM
i have checked for boost leaks apart from the pipes behind the engine which i will do this on the weekend aswell as check for saft movement in the turbo.
can any of you guys please point in the right direction to cure this problem and also if i need a new turbo can you help me with the correct turbo codes to replace it for a direct replacement .
my s3 is 2001 facelift model with the AMK engine. thanks spencer, bridgend
