Hi
I have no luck probably
yesterday I chceked my rangy with diagnostic soft due to suspension fault info on the dashboard, front left sensor is faulty, after the night my car lowered to low position, front more rear less however too.
so I start engine and pump suspension and then moved to high position
i sprayed with water the aairbag on lerft side,no bubles etc

Morover now even pumped car is lower at left side (both rear and front) with 2 cm
is it possible that faulty sensor couse self decompressing during some parking time?
i read that self leveling takes place smth about every 6 hours.

It certainly can on the P38, not sure about the L322 but if there is a duff sensor it probably could drop.
 
The L322 will level (apparently) both upwards and downwards to maintain the previously selected ride height...whereas the P38 will only lower itself to the lowest corner.

If the L322 cannot maintain the previously selected ride height, by going upwards, it will then only lower itself to maintain level, until it reaches the bump stops...

Sounds like you have either a sensor issue or a leaky air strut!

Could also be a leaky valve block assembly.
 
Sensor is faulty 4 sure (already got new, today will be assemblied) hopeful calibration will not be needed...closest garage with autologic, lynx or ids is 100km far from my location.
 
Please correct my procedure for today action
leave car on flat surface, clear fault, get suspension to highest position, take battery minus cable, change sesnor, minus cable to battery, check leveling with console switch, check faults using diagnostic soft...I missed smth?
 
Hmm we will see...job done all dimensions from ground to body the same, looks ok, no faults

I will confirm tommorow final results(after night) thx for any hints
 
Next myth busted...no need to calibrate all sides the same ground to body dimension, after the night nothing lowered etc.
 
I said"next" first was "calibration is required after brake switch change" as the dealer said...I am not sure how it looks in England, in Poland dealer charge for simple "connect to diagnostic soft" 100 pounds...as for me simple "stealing"
 
Sensors are not calibrated devices, and to ensure correct set up, it will need calibration to get correct.

It is possible to fit them back into exactly the right place so as the ride heights are efected very minimally, but to get it spot on, it will need calibration.
