Hi all, I really hope someone can help me with this?
5 months ago i went out to my car and the battery had gone flat.
Due to the bad weather i fitted a new bmw supplied battery and the problem went away for a time. Then it started doing it again and from research from other peoples problems i replaced the heater resistor (hedgehog) in the hope that this would fix it.
3 weeks later it has started doing it again. I have checked everything with an ammeter between the negative post of the battery and the cable and all seems fine as it drops to 0.06A when the car goes to sleep. Is this reading to high in sleep mode?
This time it has gone flat in less than 24hrs.
The altenator is putting 13.94 volts into the battery which i assume is high enough?
Hope you can help and thanks in advance.
