I've got a quick question, i've got an 05 clk55 amg and the start button on the shifter stopped working. I've seen a few on ebay but not for the w209. I asked someone whose selling one off a cls and he stated that everything 04 and up use the same keyless go shifter guts. meaning the pin/connector.

is this true? i called the dealer and they are not helpful...

does anyone have any experience with this...?
