Problem adjusting shocks on 2003 S500
First you need to figure out if the car has airmatic or abc. Abc was an option and there will be a button on the dash that says abc.
Second your explanation of the problem makes no sense, it could be an abc pump or airmatic pump, both of which are common failure items. But why the shocks would be too high I'd likely due to sensors or a valve body , not a pump. When a pump fails the problem us that car becomes too low
