pizzaguy your right! had a electrical diagnose $47 says it was the break light switch. They ordered the part says it will be in this Sat. it will cost me $103 plus labor = $149 wtf plus the 47$ already spent

Black03AR part 001 545 64 09 or SLK3 170.45 at EuropartsAmerica.com $19.23 wtf However this part listed under slk320. i do not know if it will fit our cars

Bill F your link looks like a bargain too!

question ... is it fairly simple to install this part?
