Year of Manufacture *: 2001
Engine Code or Type *: AUM
( Optional ) Scanner used: VAG COMHi,
Car pulls really well, boost pressure 10psi and then drops to 2 psi with obvious loss in power, checked dump valve it seems Ok but replaced to make sure, but made no difference. If I disconnect the vac line to the DV the car runs great with no problems. I checked the solenoid control valve for the DV and it seems to be working fine (ports opening and closing internal resistance all ok). Checked the archive but no luck there, any info greatly appreciated.
Mark.
