I know this is an old thread but the topic is still valid. The auto box on my 02clk 230K cabriolet started playing up not changing up after start but then working after switch off then switch on. After reading the stuff on this site I decided to change the battery. It seems to have worked on the gearbox but the front windows dropped 4" and would not close when the door was shut. I followed the advice of winding up and holding for 5 seconds and that worked. Thanks to all concerned.Does anyone know if a fix has been found for the problem with CLK windows (especially Cab's) dropping 3-4 inches after closing. Is it a new computer program or new control module?
