Hello I'm looking for some advice for my 2000 S430
Yesterday I jack up front passager side to change lower ball joint.while car was up i turn ignition on to turn wheels and left it on also i have to hit couple times upper control arm to disengage upper ball joint.when i finish i got msg airmatic visit workshop.

I try to reset by disconnect battery check connector on leveling valve and no solution.
Car is in right high while sitting if i press rising button car is rising and siting in level but while driving i feel suspension is stiff and bounce.

THANK you for any advice or solution

Your car's Airmatic system is in emergency mode. Where it stiffens up all the shocks and it doesn't release any air out of the system. Check your compressor and relay/fuse. Maybe your compressor sensor wire fell off.

On these modern computer controlled cars, you need to unplug the main battery when doing any work on the car. I replaced my Airmatic pump, relay, and fuse. With the battery connected and fried a 160 amp power distributor fuse. Had to tow my car to the dealer to get the computers reprogrammed and the power distributor replaced.

My long-distance guess is that you moved or damaged the electrical connector for the strut.

I check fuse and is good i think relay is good also because compressor turn on and lift car with rise button.i check all wires on compressor and all look good.compressor is running and when stop purge air out for 1 second

Where is airmatic computer locating?
if i swap computer do i need to reprogramming?
Is some way to test leveling valves?
is some way to test computer?I don't have any fancy computer to diagnose this just cheap OBD2 reader.

THANK YOU FOR ANY ADVICE

I doubt that you have a computer issue. On the front there are height sensors attached to the wheel well and the upper control arm. (the one you hit with a hammer?) Check to make sure the link to the sensor is not broken or bent. You could have also done damage to the sensor. It was working OK when you started and that wheel is the only one giving you a problem now. Sounds like a sensor problem to me. Resist the urge to spend money till you have eliminated all the other possibilities. And like Wally said, you could have pulled a connector or damaged a wire in the process.

Thank you for advice
Yes car was good before I change Lower ball joint(i just did passage side for now).Link on leveling valve is connect and i check wire connection and is all good.
Is car going to sit in level if one side leveling sensor is bad???
Is some way to check this leveling valve?
Car work fine rise up compressor work is in level but suspension is stiff and bounce and message on dash visit work shop

Thank you Zack

All symptoms still point toward a problem with the ride height sensor or its electrical wiring.

It was good.
You worked on it.
It isn't good.
Something that you did almost certainly caused the problem.
