FAULT CODES - whats the problem?
I had this experience twice in a week. My 335i jerked and lost power as I pushed it in low gears. The I drive shows "Engine Fault. Reduced Power".
I sent my car to my usual workshop to read the error codes, and there were 3 as follows: 1) 2ABC Boost pressure sensor, electric 2) 3100 Boost pressure control, deactivation 3) 29DC Cylinder injection cutout The guys at the workshop attributed the 3rd fault code to a possible faulty high pressure fuel pump, so I had it replaced in a hope to eliminate one factor at a time. However, I still had the same problem after the HPFP is replaced, so I believe there is another problem associated with the 1st and 2nd fault codes. I had a buddy checked if it could be caused by the waste gate actuator but it seems not. Could the remaining problem be due to a faulty boost pressure sensor? There are 2 in our 335i but the codes do not say which of them is faulty. Any ideas will be appreciated. |

If you have a tune installed, check to see if wires 6 and 7 in the small loom are reversed.

Bump to this thread
