Hi all, apologies if this has been remedied before but I've had a scroll down and search through a few similar issues but none of the answers given have helped fix the problem. So, the car has been sitting perfectly at any designated ride height for however long I leave it. Then I have the front two tyres changed and it all looks nice until tonight when I take it for it's first run on new rubber, get in fire up the engine and it jacks the front end up over and above the max height setting.
I'm sitting there head scratching as it won't drop to normal or low. I spin the wheels to lock each end to see if that clears the problem - no. I take it for a quick spin wondering if it would lower at speed - no. I just get the inactive fault and lost the lights on the height dial. Now nothing, so I checked the little rods that as far as I'm aware control the distance of travel? One had been knocked off the plastic arm so I've pushed that back on but still no lights and no adjustment.

Is there a fix without putting it in a garage or stripping the air system down?

Appreciate any help or advice

What does the dash display show? This will tell you what the ECU thinks the sensors are telling it. If one of the arms was off the sensor, the ECU will try to compensate and the sensor won't see the change, hence it pumping up the suspension to the wrong height.

Hi the dash suffers with pixilated issues but it looks like it says suspension inactive fault

Sorry not the LCD under the speedo but the big display in the middle, there is a screen that shows you the height of each wheel. What does that show?

Make sure your height sensors didn't move 180 degrees if there all good you mite be in a hard fault condition which needs diag to reset

Sorry for the delay in replying, mine is an early l322 so I don't think it has the height displayed on the screen? Been through most menus and nothing refers to ride height.

How's your battery. I ask because you say 1 " for however long I leave it" and 2 " had two new tyres fitted". 1: This model doesn't like sitting around for long periods, so the battery goes in a mood eventually, 2: some garages will leave a door open on these vehicles, whilst they change tyres/wheels. Again they don't like it and the battery goes in a huff.
Check battery condition. The slightest loss of battery power can cause the L322 to have a strop. Mine throws up air suspension faults any time she feels like it. A quick boost, or 30minute run and she's happy. On bigger strops, the power steering won't play, windows won't open, and sometimes even windscreen wipers won't work, until she's been driven for at least 10 minutes.
