My wife just pulled into the drive with a Christmas tree dashboard!

Scanning with OBDII seven modules show faults. Mostly 'Data bus error' or similar suggesting impossible signals from the thing in question. Tyre pressure loss indicator, stop-start system, stabilization control, front assist, headlight range, park pilot etc.

Clearly all of these systems have not packed in at the same time but what is the most likely cause? Module death? Bad connection? Nothing new has been plugged in and nothing modified. Cleared all the codes with OBDII and they came back straight away.

Is there anything I can check myself or is it into a garage? Car seems to drive fine although the systems in question don't work. All pretty peripheral except the ABS and stability control which are not working.

Any advice is greatly appreciated. I sense a large bill coming my way! ;0)

Thank you.
