AIRMatic problem

Guys,

I have got a w220 with an interesting problem. This model has been converted from RHD to LHD (US -> EUR), earlier, from an unknown person.

The problem is this:

the buttons to N72/1s / N72/1s3 - switches to control AIRMatic (lower/raise), do not work at all. However, it works when doing so via XENTRY diagnosis - manually leveling the actuators. But still, not via automatic leveling. What's interesting, if you do the automatic leveling - the front axle raises at normal levels (about 0mm) but not the rear axle. It says 'ACTIVE' in split of seconds, and it returns back to deactivated and the raise at the rear axle is not imminent.

Some mechanics have changed the level control valves if I'm not mistaken but they did no calibrate.

XENTRY diagnosis reports no faults in AIRMatic system.

Does your car ride at correct height and drive normally ? If so then just forget about the airnatic adjustment buttons you don’t need to adjust your Suspension

also do you mean the car was a right hand drive UK car converted to LHD for the EU ? Because if it was a US car it would have been LHD
