Air suspension XJ6

[Dennis G]

Good evening.

I have recently acquired a 2003 XJ6 and have a strange warning light issue relating to the air suspension.

After the car has been driven for about an hour, the warning light comes on saying there is a fault with the air suspension. If the car is parked for an hour or more, the warning light does not show when the engine is started again but then, as above, returns after an hour or so!

Very curious. As a layman, I would have thought the light would be permanently on if there is an actual fault.

Has anybody had a similar issue?

Thanks

That sounds like you may have a dodgy height sensor (one on each corner) and it's ok until it warms up and then breaks the connection. You might fix it by unplugging all the sensors and spraying the plugs connector pins with contact cleaner then reconnecting/disconnecting several times and a last spray of contact cleaner before reconnecting the last time.

This by its very nature will be a temporary fix and the problem is likely to come back if it effects a fix to start with. However it might confirm that's where the fault lies.

Many thanks for the suggestion but doing this is beyond my own skill level!

I will let a Jaguar mechanic have a go.
