C5 Estate Rear Suspension

[StevieOMG]

My rear suspension drops when left parked. Have had car with mechanic who a. confirms that there is no leaking fluid. b. advised that car needs to go to citroen to be put on Lexia. Mate has Lexia connected and shows no faults, hence advises that fault is mechanical not electrical.

Any ideas please. Suspension works on adjuster buttons between heights and rear adjustment button. When pump operates, it takes about 15-20 seconds to level out.

Have you checked the return lines from the rear rams? If there is a leak past the seal you won't see it as it is collected by the rear gaiters and pumped back to the reservoir.
