CL 500 W215 Airmatic

Morning Everyone
My 2002 CL 500 - W215 Airmatic problem. The white airmatic warning came on, the warning then changed to red withing a couple of minutes. As I was gently creeping home, the slightest bump on the road started the rear end 'Bouncing', caused by overcompensation from the hydraulics and sensors, which wasn't a pleasant experience, even at 25-30 mph.
As a previous Citroen owner with the similar type of suspension, I experienced much the same with that. The Spheres were the cause on that occasion.
Before I go and source these, can anyone confirm if they have had the same problem and if changing the spheres solved the issue, as the W215 system is a touch more complex than the Citroen system.

Did the rear rise up to the bump stops, if so, it's a sensor error.

Dieselman, thanks for your reply
No it didn't hit the bump stops, the back end was ocillilation with a gradual reduction, just like a wave reducing in amplitude back to normal until the next bump on the road.

You have abc on your car not airmatic... Red error normally means a valve block or pump has gone.... The system will lock out when the error comes up so it doesn't do further damage, that it why the ride goes very bouncy.
