M6 fixed.....No broken again??
Discussion
Had the M6 back for two days following my spring and tyre failure last week and was driving to work
this morning when the radio and headlights cut out for a second and I then got ABS control module failure,DCS,Hill start assist etc etc error. Error stayed for around ten seconds then went out. Happened 3 times on my 22 mile journey.Anyone had similar issues ?

At the moment mine seems to just be ABS and associated bits that rely on the ABS sensors such
as DSC and hill start assist.Nothing on the warning so far that mentions gearbox anyway.
Just took it out for a blast now and the warnings never showed? Will see what it's like at
5am Tomorrow on the same journey to work as Today?

My guess based upon my own experiences withe the same errors - voltage regulator. When the regulator starts to fail it allows voltage spikes to occur and some of the car's electrics shut down to protect themselves. It's a £60 part that can be installed from underneath without removing the alternator. Fiddly and you can't see all of what you're doing but it can be done.
Best way to diagnose the problem is to connect a voltmeter to the cigarette lighter socket and see if there's a voltage spike occurring when the warning lights pop up. I was seeing17-18v spikes - not good!

Nope it drove fine apart from the heavy steering, P500 still available no problem. Seemed to be some sort of spike that cut the headlights for a second and rebooted the idrive screen. Just popped down to the shops in it and it ran fine with no warnings present. See what happens in the morning?
The alternator is probably fine - just the regulator needs replacing. The regulator isn't available as a separate part from BMW but can be bought through a good auto electrician. There's a good DIY on m5board.
The auto electrician I spoke to commented that he sees quite a few of them being replaced far earlier than a conventional regulator would be - the regulator is controlled by one of the car's ECUs (presumably via the CAN bus?) and as it lives in a harsh environment (hot and vibration prone) they don't last that long.
