My switch is damaged, sounds do have an airleak and is missing the button covers. Is this part interchangeable from any other benz like ithe one in the last pic i attached? Can i just buy the little covers for the switches and that will stop the leak? Lastly if not does any one have a part number for this item?









this is from cls may it work?

That last picture wouldn't work for you to my knowledge, the switches are oriented differently than your original switches. I had to have my seat contour controls fixed, didn't work, which is a very common issue. As you know, it's an air bladder and pump system that's prone to leaking and the pump failing. You develop a system leak, and the pump runs continuously to try and hold the pressure, causing the electric pump to burn out. Also the fittings don't seem to age well.

You can buy a repair kit for them, which is what my mechanic told me he did, but I couldn't tell you where to get it. But, I'd start with the pump to make sure it still works and then work your way through the fittings and up to the switches.

I see , my pump still works fine , the buttons on top came off and there is a leak some where that i can hear. I guess ill just take it apart and fix the leak.
