Renault premium air suspension fault

Hi All.Just after some advice I have a Renault premium that burst an air bag today.After replacing the bag the driver now informs me that the suspension has been going to full height for a couple of days now.Which is obviously the reason the bag blew.Ive tryed changing pressure sensors on bags but no change and tryed another controller in the cab but no change.Has anyone else come across this problem before I get it plugged in.

Thanks in advance.

have you tried the ride height sensor?

Had a problem with one on an FH, and when it went wrong it stuck it on max height.

Also, check the wiring is sound before condemning the level sensor.

Hi all.Just thought I would update on the cause.I got it plugged in but no codes.So after doing activation tests on all components turned out to be the o/s control valve faulty.Theres two that sit in the chassis just in front of level sensors.
