I have not been able to find what the code 801C20 mean?
Scan tool is showing
801C20 ZGM: central fault memory full - control-unit fault
I haven't noticed any issues with the car except I was having drivetrain malfunction then replaced the battery and for now that seems to be fixed but now this code is around
Any advise would be great I notice many people have the code but never follow up with a fix
Thanks
Have a shop read it but if the cars fine just clear it
Will the shop get a different reading and more info than what i got? I used a proper bmw scan tool.
If you don't have any issues, then don't worry about it. BMW's set erroneous codes all day long. I can scan a car and have 50 fault codes set, and only one fault will be relevant to the issue at hand.
