Help!  Superb Mk2 has frozen MFD, will only show travelled time. A coincidence maybe, but an airbag error showed up a day before this, also the horn stopped working (not sure about when exactly as I rarely use it).

Any ideas would be appreciated.

 

I'm only guessing but all the affected stuff seems to be in the steering column/MFSW area so my first guess would be a broken wire, bad connection or bad earth in the steering column wiring. My gut instinct would be a bad earth or possibly the CAN Bus wiring as it affects multiple systems. Have you checked all the fuses?
