Hi everybody.
When the car is not used (2 days) the front of the car lowers. Only the front. Air struts where changed last year .
Checked all the air lines for leaks. Nothing found.
Anybody has any ideas. Fault code C1130 .Front valve block seems ok no external leaks.

Hi, I had a similar problem where the rear was lowering. Can’t remember if I got the same fault code but the rear offside sensor was not working so I changed it and it solved the problem. From what I can remember the whole of the rear of the car lowered because one sensor was not working, might be an idea to check the sensor to see if the wires are broken or not.

Just remembered to add that once I started the car the rear end did rise up to normal height and only lowered when parked up overnight.

It takes a while for the car to lower( 2days). I think it's an air valve that fails but I don't know which.
