hi can anyone help? had intermittent multiple errors on idrive, have read some previous postings about changing the battery. this i did with a suitable bosch, programmed the car with the new details, all fine then the day after while on the motorway the dash lit up like a christmas tree.
failures include, ABS, servotronic, suspension, tyre pressure warning, seat belt warning.
plugged it back in while all theses faults are displayed and the only fault we can find was is in power management heading, this read relay 1 failure?
the charge off the alternator is 15v
have i got to go to the dealer?
Any help would be great
