I wonder if anyone can help me get to the bottom of this highly annoying habit my E60 has.
unlock car - open door and red trans fail message on dash. Even before I put the key in.
Turn ignition on.
Trans fail - drive moderately
Cruise control Failure
Fuel Pump Faulty.
Fuel pump can be heard whining away in the boot.
Turning off ignition and waiting sometimes clears this.
What I have done so far: New DDE sky blue relay. Checked DIS when the fault crops up. I have voltage at the CAS on the PT WAKE terminals. If read the CAS info memory I see Message receive errors for Various modules.
Terminal 30 relay *seems* ok, if I remove this I get ABS/DTC/dynamic drive errors instead.
I have a brand new battery on, that I coded to the car, and replaced the glowplug controller.
