Hi All I have some recently developed issue with my 2003 2.0 Hdi C5 SX Estate. It started to lower itself when I parked up. It takes a couple of hours to be visible, mainly on the rear but probably on the front as well but that is not significant. I'm not sure if there any link but I had some suspension issue since I bought it last July. When the steering wheel is approximately halfway to one direction (when the car stationery and the engine is on) the level on the front moved up and down frequently. that was annoying but easy to avoid. I also have a broken level switch in the boot. Back to the "new" problem, when I open the door or unlock the car with the remote the pump starts and bring the car up to the normal level. What I checked, oil level in the reservoir, OK, no leakage visible under the car. I just going to check with the Lexia, but I don't think it will show anything. I'll let you know anyway. Is there anyone experienced similar problem, any solution for it? All input would be appreciated. Cheers
