Default 2003 X350 Suspension Error.

Hi, I have an amber suspension error notification that I can't delete with my icarsoft but I can by turning engine
off and on again. The garage had it for a couple of days but couldn't find any faults just the message.
Any ideas?

It could be there is an intermittent failure. You said amber lights clears after engine restart, right? So possible it clears DTC as well. I would make sure that DTC scanned while light is on. Mine Icarsoft 930 can scan B-codes. I keep it in car all the time, just in case, that way I can read codes right away.

Hi, thanks for that, dash displays fault, icarsoft 2.0 LR shows Level Plausability Error but won't erase.
Turnin butg off and on again removes warning. Nothing wrong with ride height but live data gives
very strange sensor measurements, -19mm rear left, 4mm rear right. I am confused. Maybe just ignore
warnings?

Have suspension been calibrated after air spring replacement? Could it be that sensor got damaged during repair?
I am just guessing.

Get undrtneath car if possible or jack it up . Check your hight sensors. Bracket to arm, bracket to subframe bent and the sticks not broken at plastic piece to bracket or to black box

What code did the I carsoft give you?
anothe thing related to the airsuspension is
the headlights Xenon On 2003 have selfleveling...have a ballast in the lower part , if you put in new ballast it will not support headlight leveling and you will have an amber light on the dash.
