[Ovmsdev] battery drain

[Michael Balzer]

Tamás,

first of all, are you sure these errors are new? Check your log archive 
for the error pattern. An occasional "stuck bus-off error state" is 
normal for many vehicles, when the car is off.

The 12V battery may just coincidentally happen to fail right now. How 
old is it? If it's relatively new and/or the errors didn't occur before, 
it could be an issue with the OBD connection.

Regards,
Michael
