I noticed the lumbar support on both sides does not work. I previously posted a question about the door lock vacuum pump located in the trunk keeps actuating going down the road. All door locks and trunk work fine. Does this pump also control the lumbar support? Is there any place the lines tend to kink or anything I can check for. If so does any one have a diagram for the pump? This is on a 2001 clk 430. Thanks in advance.

Found a broke vacuum line adapter hooking up to the passenger lumbar adjustment panel. Anybody know where I can find adapters.

I have the same problem. What did you do to resolve this?

Look under your seat there might be a broken line like mine !! You can use a rubber vacume hose from any auto parts place and fit over the two broken lines.
