Strange iDrive fault on 535d

[Ultraviolet]

All

Any BMW techs out there that can shed some light on this....

on a couple of occasions (since my CIP was updated about 4 weeks ago), the screen on my car has failed. When starting the car the screen stays blank, and remains blank (with the occasional grey flicker) until I turn off the ignition, wait for around 30 mins, then restart.

The engine will start and the car can be driven, but obviously non of the iDrive controls can be used. If I try to turn on the stereo by pressing the volume knob next to the in-dash cd player, this doesn't work either.

any ideas what is causing this? its a bit of a pisser setting off on a long journey without satnav or music.

to me it looks like the iDrive is failing to boot... does this sound possible?

It's the professional satnav, with the car on a July 05 registration. The CIP upgrade was to 25.1 IIRC.

Not sure if it can be the battery as the car started fine....?

It's booked into the dealer, but if anyone has any more thoughts I'll pass them on (they've already replaced the screen).

any other ideas?

cheers,

Thanks Aero

I'll give the master reset a try next time it freezes. Maybe another CIP update will sort it out? We'll see if the dealer has any suggestions.....
