E420 cdi - low and high Voltage faults
Hello. Ive just bought an E420 cdi. Have been having problems with low and high voltage faults.
Replaced the auxiliary battery, main battery and the voltage regulator as they usually cause these faults in my experience. Since auxiliary battery replacement the battery maintenance message has started coming up. Ive also checked most of the grounding points for corrosion but can’t find anything.
anyone here with a whole lot of w211 knowledge have any ideas?
