My first real issue since buying the car a year ago.
I have a suspension fault which flags up.
The car sits at normal hight but will not go up or down.
Just after the suspension fault pings the Adaptive Dynamic Fault appears.
Here's the iid faults

C1A00-1D can be caused by rear air suspension control unit.
So clutching at straws I have order a new one.
Does anyone know if the adaptive dynamics fault will be fixed if I get the suspension working g correctly again???

I had the active dynamic fault come replaced the front cables on the front strut tops but the fault was still there so could not access any of the special programs eventually the fault was found out to be the rear ride height sensor had gone had a new one fitted job done

Those are all invalid data received from modules. Sounds more like a can bus fault to me but would check modules first, as the first fault might well be a clue though. Circuit current out of range could be a short, poor connection, or one of the modules drawing too much. Too many toys, not enough time

Looks like I have solved the issue.
I disconnected the rear air valve block sprayed the connector with wd40 and plugged it back it.
Cleared the codes and all the errors went.
I have been driving it round for the last couple of days with no issues.
On to the next problem.
