[quote=""fenj66""]hmm, ive just tried the obc voltmeter test on mine as im suspicious of the battery as the aux heater is having a bit of trouble lately. the car starts fine tho even in these cold temps but the aux heater powers down after a couple of minutes.
anyway: with the engine off the volts show 12.0
starting the engine drops down to 11.8
and with engine running the volts rise to 13.8
does this sound like a bad battery to anyone?[/quote]
Hi My webasto does the exact same thing, if you work out whats wrong with yours please let me know
thanks

Re: Battery Condition?
My battery is 5 years old now and I want to change it.
BMW quoted me £238.16 for the BMW AGM 90Ah 61216924023
First of all (I have noticed that there are very knowledgeable people on the forum) I need to decide on technology:
GEL vs AGM? what would be better for a E53 2005 reg diesel with plans to use (if i can get it to work) telestart T91 (T100 ideally)
