I was away the last couple of weeks and noticed today that the onboard clock is slow by about 30 mins. I'm assuming the lack of driving is responsible but 30m seems like a lot. Battery issue? I'm pretty certain the battery is factory original. Is it time to get it replaced?
Are you noticing any other issues like intermittant random lights flickering on the speedo display? Maybe check the battery is charging alright, might have a cell on the way out.
Nothing like that. I checked for faults and there's a bunch of CAN LOW faults on various modules. I'm guessing there's either a faulty module on the bus or it's the battery.
Did you go above 88mph recently ?
Depends who's asking. You a cop? :DQuote:

Properly looking over the error codes now:
A559
E104
A4EA
A4F2
D904
A0C1
C904
D944
D947
E584
Most are CAN Bus related but A559 (power loss to instrument cluster) and A0C1 (Short circuit or signal interruption) would suggest a battery issue.
Drive your car otherwise if you are lucky to have a garage use a small power supply if it stays for weeks parked up.
Or lend me the car for a few weeks I will get the battery charged up free of charge :-)
You're truly a selfless and generous person. But no.Quote:

If you want to do the energy diagnosis just give me a shout, I can be found on Dublin's south side sometimes!

I think you'll find it's your loss :)Quote:

One for the e36 in storage & one for topping up the 6 Series every now & again. BMW will prattle on about the "unfavourable driving profile" alright. Design few in car electric system more like!
I haven't and don't have time - I just got back from 2 weeks in the US and I've more travel booked. The car is going in for new brakes this week so I'll get a new battery added to the list.Quote:

When I am here the car does about 50km/day. The last 2 weeks have been the first time since October it's been let sit for longer than a weekend. That said, I'll only be in the country for another 5 days this month. I would have thought that up a month would have been ok to leave a car sit idle unless the battery was really on the way out (which is what I think is wrong here).Quote:

yeah use to happen to golf batteries too, always replaced come spring when it went back to 18 holes the battery wasn't able for itQuote:
