2002 S55 suspension issue
 

I have a 2002 S55. I bought it about five years ago. It "squatted" when idling for more than about 5 minutes. I had a little warranty time left, so I took it to the dealer. He did some small thing, supposedly, and off we went. It was not fixed, and the warranty time ran out. It was not a big deal, so I lived with it. then, about two months ago the ABC light came on. I took it to a shp that I had used in the past on other MB's I've owned. He said the pump was bad, and he replaced it. When I picked it up, the light came on! I took it back three mroe times, and he says there is nothing showing up on the diagnosis screen, and he cannot help me!! This after spending nearly $2,000 on the issue. I parked the car at the airport for a week. Upon my return the driver's side rear was down to the point of nearly hitting the tire. I started the car and hit the "raise" button. the car raised immediately. How can I diagnose this problem and fix it myself. I have worked on cars for years. I feel if I can properly diagnose the issue, I can fix it. Anyone know??

I am having ABC Pump problems myself.....
 

Please call me if anybody has some good information on where to buy a ABC Pump. I need on and don't know much about these pumps and am trying to get one for less money as I don't have alot right now.

Any suggestions?:(

I found a company in Florida that remanufactures OEM suspension products such as struts and pumps. I know the struts are warranted for lifetime. I just bought one, and it is being installed today. Their website is http://www.arnottindustries.com/. Their phone number is 800-251-8993 extension 101. I spoke with Will, who was very helpful. Try them.
