Hi Lads, sorry if this has been asked before but a search did not produce any hits, I left my car in with BMW dealer for 2 days for some small collision damage repair. New bumper and grill. When I got it back the battery warning light came on straight away. I phoned them and they said the would have no reason to dissconnect the battery. The only thing I can think of is the had the radio on for the 2 days it was in the shop and the voltage is down a bit. Anyhow, Is there a reset for this or should I just go for a long drive to charge up the battery again?
Its an F10 520D.
Thanks.
