H.. I'm new to the forum and, sadly,not a happy bunny. I've always enjoyed my mercs in the past (300TEs) and now have an E220 estate with a "simple" problem. Front offside side light has stopped working. It's not the led that has failed because it lights up at night when I unlock the car. When I start the engine, however, it goes out. Must be a "simple" bad connection...right? It seems that to find out the car has to be plugged in at the dealer's workshop (£99 just to get started!) This should then show if it's the control unit that's at fault and needs to be replaced (£400 and the least expensive option) or the actual headlight which needs to be replaced (£1300). End of the story....£500 plus 2 hours labour minimum or £1400 plus labour to get a sidelight working! This does not show up Mercedes in a very good light (excuse the pun) and has me now waiting for the nearside to follow the same breakdown. I think my love affair with Mercedes is coming to a sad end.
