JBE: K-Can Communications Fault *RESOLVED*

[jaye944]

Hey guy's

Weird problem,

Started car up today, got to work, switched off, then I got message similar to

"Passenger restraint failure"
"Service lift logo"
"Take the car to BMW do not continue to drive, electrical issue"

or similar.

Left it

went out to car now, all good, nothing on the idrive. will check codes
do I have a problem ?

cheers

Got home and as I tried to switch the car off, got the "there is an electrical/electronic fault again" CD switch would turn on or off, radio, was acting weird
Car wouldnt switch off from the button.
logged on and there was like 38 codes, I checked the battery and the "histogram" would not display, but the "last" 5 days battery showed as good
screenshots of the codes are on another PC, will try and pull them off and post them

(dropped car of at Dealer BTW afterwards)
