C2302 - Fault - ongoing investigation

[J44EAG]

An interesting and informative thread. Glad you got it sorted.

The spec between sport and comfort air springs appears to remain a curio. It would certainly be useful to get a definitive answer as to just what the differences are internally between green spot comfort units and the red spot sport alternatives.

Height on any X350 model is easily adjusted via a dealer level diagnostic tool. I`ve had that done on my XJR which has lowered the car all round by 15mm. As the car ride heights were all over the place when I got the car, we initially got the car leveled all round, then added the 15mm which dropped the car down...not too low but just about right without the car looking "depressed".

Well done.

Have this code along with the car rising to max height in the rear. This problem seems to be floating around the forums but I cannot seem to find a conclusive answer on what causes this. As this is a unique error (the rear rising to high), there are likely on a few things that will fix this.

Hi laxexquis288,

Have you checked the ride height sensors on the rear? These are attached to the lower arms. Are they connected and do they look intact?

Do you have a icarsoft i90 scantool or similar? You can check the left rear and right rear ride height in real time in the control module.

If the ride height sensors are reading low but the car looks like it's high at the back it could be the sensors.

Hope this helps.
