E63 630 Engine light
Discussion
Afternoon, after almost a year of trouble free motoring in my 630, today I was greeted with the Engine light illuminated.
Some background:
For months I’ve been ignoring the Irregular Battery Discharge message. The car always started and this battery message and clock reset only occurred if the car was not moved for 3 or 4 days or if I only did short trips. Once I had completed some 80 mile work commutes the message would go and all was good. I assume the long trips charged the battery enough.
Today the clock had reset and I had the yellow message with a car on the ramp and the battery discharge message. But it had the additional EML today that refuses to go off. I’ve plugged in my normal OBD scanner which I believe isn’t enough to really read the BMW messages but I did get a few errors returned regarding an open circuit. Car drives fine, no limp mode etc
Could they be related in the fact that the battery is now so poor that it’s causing other errors elsewhere in the car? Typical it’s MOT next month and will fail with this light on. Tempted to go for a long drive to charge the battery again and see if the EML goes off....
Cheers

Given the faff with the battery, is there a reason you just haven't bought a new one? 
Yes, low battery issues can cause various (seemingly unrelated) error codes.
Out of interest, what is the spec of the battery currently fitted to your 630? Just checked mine and it is 95Ah and 800CCA.

Managed to clear the engine light with a BMW code reader from Amazon.... no idea what it was related to. The reader gave loads of errors from the sat nav to gear switch to adaptive lights (which I don’t have). Cleared the lot and the light went off. I’ll see if it comes back.
As for the battery.... just me being lazy. A fault that comes and goes in a car I wasn’t using that much. The green light on the battery in the boot says it’s charging and healthy but that’s obviously only part of the circuits I guess. Looks like you have a stronger battery than my one
I’ll replace the battery soon

IMO it needs a new battery...As for the battery.... just me being lazy. A fault that comes and goes in a car I wasn’t using that much.

Fit the biggest you can and get it coded to the car
It doesn't need to be an AGM battery IIRC; so a Yuasa or Bosch 019 style battery will be more than enough
But it does need to be coded to the car

Agree, biggest battery definitely a good idea. Lots of electrical systems on the 6 and battery grumbles can cause random issues.Fit the biggest you can and get it coded to the car

Mine is an Exide iirc.
Can Carly do battery coding?

When the starter motor earth went on mine I got all sorts of code errors caused by the low battery voltage. I would definitely get the battery changed and I would get the charging and starting circuit checked over.
