So my 2009 500 has developed a fault where the engine management light came on the other day
I had a friend scan it (he’s not a mechanic)
It came up with U0001 CAN high speed bus
The fault can be cleared but comes back on again after a few minutes driving
The car performs as it should and stops and starts just fine
I hope someone on here has had a similar fault and can give me some tips on where to start
