Cars booked into an independent BMW garage today so I'll update on how it goes...

Thanks - much appreciated. I'd read about coding the battery but I understood it was not needed on the 2006 model. Is there a vin number that it starts at? If it does need coding, is that a main dealer job? There's so many contradictory reports on the Internet it's hard to work out how to do it! Thanks - much appreciated.

Hi Tried with the battery disconnected today znd the engine died immediately. Would this def be a faulty alternator or is the a fuse or such that could be dud? Thanks,

Hi, Thanks - Battery is a yuasa 5000 silver from halfords. 900 cca which is higher than the bosch it replaced. Both alternator and starter are NAPA, bought from local motor factors. All the leads are as new - never seen a car so clean. I'm out atm so I'll check later re disconnecting battery. From what I can see there's no coding required. The negative is a straight lead with nothing like an intelligent monitor.

Hi all, I have a problem with my e83. It started about a week ago when it started to turn over really slowly. Tested the battery and it was showing under 12v so replaced it. Then it wouldn't start. Recovery agent advised starter motor. Replaced. Started ok but not charging battery. Battery light comes on intermittently, drives ok but low on power and wipers are slow. Replaced alternator with new unit. Reset on board computer menu. Still no change. I'm totally out of ideas! Thoughts? Thanks in advance...
