I just bought a W211 wagon, and its missing the button for the power headrest switch on the passenger door. Normally, I'd go to the TeileKatalog and look it up, but when I click through the front door figure to see the Door Panelling breakdown, I get nothing but jibberish text. I've tried Mac and PC, and Chrome, Safari, and IE with the same results. The front and rear door figures are the only ones that do this. Does anyone have the part number for the button?
