L322 02 Air Suspension inactive fault

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
