All of these come on together:-
Tyre pressure monitor fault.
ACC fault
Air con not available,
Auto hold fault,
ABS fault,
ASC fault.
I can drive a couple of miles and they all go off again!
Sometimes they come on when I start the engine.
Last week I swapped front wheels with rears as the insides of the front tyres are scrubbed out due to an alignment issue. I then drove 200 miles without an fault. Now my dash is like a Christmas tree.
I'm thinking maybe 1 fault in 1 system is upsetting all the others.
Before I plug in VCDS, is there anything obvious I should check please?
