Seems my 2004 XJR has decided that now is the time for the suspension to start malfunctioning. Car is rigid as hell. Front suspension seems to be at max height.

I have SDD but I'm scared to use it to recalibrate incase there is a failure with something else. Can anyone advise?

Rears seem fine. The compressor does release pressure when I park up in the driveway, can hear the hiss as it depressurises, so I assume the exhaust valve isn't blocked.

 

Maybe the front ride height sensor has something stuck in it? Its mounted in harms way, so maybe a leaf got in there? Sorry, I forget which side it is.

 

Well you have an SDD and the air suspension stuff is pretty Jaguar specific so I would suggest getting SDD hooked up and see if it will tell you anything.
It's safe to read and clear codes if your afraid to try the re-calibration procedure.

As posted above it might be a front height sensor. Also I forget what year they went to a single front height sensor? So your car could have 1 or 2 sensors as the later cars only had 1 front sensor. Easy to check with the car in the air. They are plastic and they can break and come apart.

My 04 has one front height sensor, so I think its only the earliest x350s that had 2.

 

I've ordered replacement sensors and stainless steel brackets.

Will report back when the work is done so this will benefit other people in the same boat.

 

So the sensor was broken?

Don't know

 

I had the same problem, but at the rear. In the end it was a height sensor.

Recalibration after the replacement of the sensor was a bit tricky, as SDD said the the rear was out of range (it was at maximum height, same as your front shocks are), so I had to deflate and reinflate the system before the calibration worked. Can all be done with SDD.

But don't be afraid, you can do it!

Best regards,

So I got scammed. Does anyone have a new GENUINE C2C2242 sensor for sale, or know of one?

 

Ouch. Im sorry. I looked at replacing a rear one on mine, but in the end I deemed it too expensive and unlikely to be guessing at. Its only a rheostat thing after all and after removing and testing, it seemed good. My personal judgement, not advising at all. Anyway, as I recall new ones were Close to $200 each range from the places I tend to go to- Barratts, Moss, and the like. I dont remember if David Manners had them, they're excellent to deal with but dont have the broadest selection.

 

Cheers mate. I THINK I may have ordered the last genuine sensor on the entire planet, or else I've been scammed again. Should find out in a few days haha.
