I'm having trouble with my AGU which seems flat as a fart. It doesn't seem to be boosting and has no power until above 3k rpm and even then its still rubbish really. There is just NO torque.
Ive just done a boost leak test and system holds 15psi without any leaks and all vacuum lines are new. I briefly bypassed N75 to to see if turbo works ok and it was a totally different car to drive, could here the turbo spool around 2k and car pulled very strong.
My problem is VAG COM shows no faults at all and with no boost or vac leaks I guess it must be the ECU deciding not to demand boost ? Due to a sensor ? But no fault codes !
Any help greatly appreciated.
