Intake Cam Position Sensor Errors 2001 e39 530i 98,000 miles
Mark you might want to check the pins in the sensor connector. If you
have access to a voltmeter it is easy enough to check for bad electrical connections. If your new gasket holds the face of the sensor too far from the cam you will also have problems. There is very little margin for error in positioning the clearance between sensor and cam. It is also possible that it is trying to tell you the cam isn't in the correct position at a given engine RPM. BMW codes are a bit sketchy when it comes to defining a problem. Hooking up a good diagnostic analyzer can tell you what degree of advance the system is seeing at various RPM's.

Don't assume anything.
Every BMW Independent Repair shop out there knows that only genuine BMW sensors work. The Febi is junk.

Intake Cam Position Sensor Errors 2001 e39 530i 98,000 miles
Following several '41' errors, once followed by a limp home mode
episode, I replaced the sensor with one from Febi. The sensor came with a gasket that was rather small in cross section. I bought the "thicker" one recommended by the seller. With this recommended gasket the sensor seemed to fit more snugly. The holding bolt is snug. Now I am still getting the same error Namely , 41 from table 19 using my Peake code reader. Assuming that the new sensor is good, do you have any ideas why I am getting this error? Many Thanks, Mark |
