Peake fault code 1A
Hi have been having peculiar problems with my 325i 1992 , surging on idle
through a process of elimination have put it down to Mass Air Sensor , got another one on its way , funny thing is even when i disconect the MAS i get no check engine light or anything . Used a Peake Scanner last night and got the reading 1A control unit supply , can anyone tell me what that is that appears to be the only fault even when the MAS is disconnected. Thanks Glynn
