i just bought a 2001 S500 runs and drives great but when shut off L/R sags bad when the car is started and you push the button that raises the car it pumps up even if you shut the light on the switch off it still rides fine no warnings when you park it lowers back down on the L/R only any advise.

 

 

Ok, I replaced the rear shocks found the compression fitting on top of the rear strut was the problem soapy water found it Thanks for the help

 

I am a proud owner of a 1999 s430 Mercedes benz. Recently I've changed the two rear struts with used ones but it didn't rise at all. Any help will be appreciated

Thanks in advance

 

 

Carlos,

I would suggest that you try what is wrong first, as there are several possible causes for your problem. Some of these include:
Blown or faulty fuse.
Air leak in the system.
Worn compressor seal.
Fault in the Airmatic valve block.

The more you learn about the Airmatic System, the easier it is to fix. You might start here:

I have changed the pump, valve block and two rear shocks.
The pump comes on once I start the car still nothing happens

 

The trick is to have it in all four struts, or the pump or something.
I just park up my s class, and 10 minutes later, it's stanced. Looks like one of those hondas that get stuck on speed humps
