Technical Service
SUBJECT
All Instrument Dials Inoperative and Display in Instrument Cluster Is Bright
MODEL
E60, E61 (5 Series)
E63, E64 (6 Series)
Vehicles produced up to August 31, 2006
SITUATION
All instrument dials are inoperative and the illumination of the information display in the instrument cluster is very bright.
The message "gearbox malfunction" is often displayed, followed by "Active steering" or messages relating to other PT-CAN system failures. The faults change frequently, and disappear again without a power cycle. The faults appear intermittently when the vehicle is stationary with the ignition on, as well when the vehicle is in motion.
In addition, the control units of the PT-CAN are sometimes not detected by the diagnostic tester. No faults are stored in the EGS, but CAN-Bus faults are stored on other control units.
CAUSE
The wiring (2) is chafing on the horn bracket (1), located in the area behind the right headlamp.
CORRECTION
Repair any affected wires (refer to B61 01 07). Unless the wire strands are cut, reinsulating the affected
wires will provide an effective repair. Protect them from further chaffing using corrugated tube.
