BMW X5 E70 4.8 - Rough Idle and Misfire at cylinder 8
Hi there guys, i have an issue with a X5 2007 4.8i.
Before changing the chains, oil pump and everything on the engine.. there was a missfire at cylinder 1. (This was before a year ago). After changing everything, car was working fine, until started saving misfire at cylinder 8 with errors: These two comes together 2E2B 2D32 And sometimes with 55C3 - which i consider is the lack of the engine power. After driving it for like a week or more.. but sometimes it could occur day after day... gives these errors: Spontaneously.. i've reset the adaptations of the throttle body.. also the body is clean. Coils, Spark plugs are good. 2CF0 2CF1 2CF9 2CFA 2CF8 2D00 2D13 I am thinking about the harness that goes to the throttle body. I saw that it is an issue on these cars.. With INPA it shows when saving the errors that: Voltage throttle valve potentiometer 1 - 0.86V Voltage throttle valve potentiometer 2 - 4.20V Is this okay or it means i am correct about the harness ? With all these error car has rough idle. After cleaning the codes.. car works just fine with no symptoms of any issue. |
