320cdi errors
I have error codes 9090, 9051, 9055, 9040. Message on the display says KOMFORTFUNKTIONEN VORUBERGEHEN ABGESCHALTED.
The charging voltage then drops to 12.7 V. Several times also jumped to nearly 16V.
Can anyone help? Do you replace the alternator or the fault of the BCM? I think it's the alternator.
thanx
Kris
