X5 gone wild....errors galore

[1fastm3]

So my '07 4.8i went crazy on the drive to work today.

Every malfunction came on the iDrive...Electrical system, RFT, EDC/Susp'n/etc. Car drove fine (save for a funky signal light...delayed and slow, and the power lumbar supports were opening and closing at whim) other wise.

The tach and speedo died too.

Here's the codes that came up:
(the scanner did not have BMW specific software, but it is a $1,000 model)

U0100---lost communication with Engine Control Module/Powertrain control module

P110F--Ambient Temperature Sensor Faulty CAN Signal ((this I googled as the scanner said "description unavailable"))

U0155---lost communication with instrument panel cluster (ipc) control module

P1551 Manufacturer Controlled Vehicle Speed, and Auxiliary Inputs



Charging system is fine at 14.7.



Any idea as to what occurred? Freak BMW Electrical issue?


Thanks!
