This has been a bit of a developing saga!
A few weeks ago I started getting a warning saying 'high rate of discharge' on the dash. Also the car seemed to be a bit heavier to start. Then my integrated bluetooth system packed up - and from what I can tell the car thinks there is no bluetooth module installed. Then this morning the idrive screen and the radio stopped working - no music and nothing visible on the screen.
I had a look in the boot at the battery this morning, and the battery is a genuine BMW replacement and it has a sticker on it saying Sept 2009, so it's not that old. It has a charge indicator on top of it which is showing that the battery hasnt got enough charge, but it isnt showuing that the battery needs replacement.
So then I thought, maybe the alternator is packing up. Is this possible, and if so would it cause things to stop working due to lack of battery power. Not sure.
I'm getting someone in to check the charge off the alternator, but does anyone have any other ideas?
Thanks for your help in advance!
