L322 suspension fault

corgireg · Nov 5, 2023

I have a suspension fault on my L322 3ltre 2006, I've replaced the air spring and height sensor on the rear left hand side, but it still goes down if left for a few hours, anyone got any idea what could be the cause

Did you check the spring was actually leaking? What was wrong with the height sensor?

I didn't check if the spring was leaking, just assumed it was and changed it, when that didn't work , I thought it must be the height sensor, so I changed that and it seemed to work, but this morning its down on that side again

Firing the parts cannon can be a very expensive way f fixing things. It may well be a height sensor problem but after replacing it the suspension has to be calibrated.

Sounds like its time to get out the spray bottle of soapy water and check the pipes and connections.

Diagnostics would be my suggestion. Replacing the strut made no difference so I would say that the original fault was not a leak.

Loving the ‘parts cannon’ Datatek, it’s left me chuckling away
