I'm new to this forum but I'm sure I'll be back again as we have three BMWs in the household (as well as the 530d Touring I have an S-reg 328i Touring, and a V-reg M Coupe). Just recently something has started draining the battery on my W-reg 530d Touring. The radio used to switch off with the ignition but now doesn't. The parking light next to the gear stick stays on even when the car is switched off. Could these things be related to the draining of the battery (which is only 3 months old) and if so what do I do to stop it happening?
