Hi had a problem recently with the battery draining over night.
Had alternator and new batter fitted as per advice and hasn't resolved the issue.
I now have a diagnostics report which may or may not help but here are the codes :-
BMW Scanner v22.214.171.124
7B/71 - Signal, characteristic map cooling, short circuit to positive
25/61 - Main relay, reaction delay, not switched or switched with delay
94/21 - DWA-LED: open circuit or cable DWAL, KL30
On another machine :-
123 Activation, Map cooling short circuit to positive (p1620)
37 Main Relay: Switching delay [Main relay does not switch/Delayed]
This is driving me crazy as I now have to jump start the car every morning
Any advice on what the codes mean and are they related to my problem, some help would be appreciated.
