2002 XJR - CATS Suspension

[janktatar]

I would be grateful for some advice please.

Just recently my XJR appears to have developed a suspension fault in a way that the suspension has become very hard creating a bouncy/harsh drive.

No fault message has appeared on my dash, but if I pull one of the connections of a damper the message appears “suspension fault” so that appears to working as it should.

I am lucky enough to have a second supercharged Daimler of the same age, so I have replaced the ACD control unit and accelerometer one of the time to check if there were any faults. Despite this change, the car suspension is still hard and bouncy when driving.

So I replaced the original parts back on the car as they clearly not at fault with the original units.

I am at a loss what else is creating this problem.

Any help or guidance would be greatly appreciated. Thank you.

Yours

John
