2002 XKR-100
"Suspension Fault" shows up in my message center after a few moments on the road. I am wondering if replacing the air system with coil overs is a practical solution on a Jaguar. I have done so, years ago on an American car and was very happy with the results, but I am worried about all the electrical/computer things related to the Jaguar.
I would appreciate any advice

 

The XK doesn't have air suspension, it's a coil over setup with an adjustable shock.

Getting rid of the message is as simple as unplugging the control module at the rear of the spare tire well. The best way to find out what is actually wrong with the the suspension you will need to get the codes read.

It could be as simple as a bad connection to one of the shocks, or a problem with a shock or one of the accelerometers.
