High battery drain
Hi all, hopefully someone will be able to help me out here. I have been having problems with my 2005 E60 525 where every morning the battery is completely flat. After searching on this site I have learnt that this is not an uncommon problem. Reasons varying from the IBS, Hedgehog and the comfort system( or something like that). Following guidance i borrowed a multimeter and carried out a drain test which showed a huge reading of 5 amps. I believe it should be around 0.03 amps. So before i put it into a rather expensive dealer can anyone suggest what might be causing such a large drain. Thanks in advance.
