Hi, and thanks for the membership. My name is Lasse and I live in Norway. I wonder if anyone can help me? I need a new motor control module for my 2007 w221 S500 4matic. Need a replacement for A 273 153 50 79. Must be open and ready for programming. Anyone who knows where to order cheapest as possible? Thankful for all the answers. Best regards, Lasse from Norway.
