Hallo, I got an Golf with the famous BAD 1.6 FSI and posssibly a bad high pressure fuel pump, fault code fuel pressure regulation exceeded , Vcds shows at idle reving it at highest 15 bar , and lowest 3.8 , from fuel pump in tank, So anyhow i wonder if anyone have a working pump or some one who can rebuild one ,
