Matt,

Had a look in the module box.....quite a lot of stuff in there!.....Clearly the ECU is the biggest thing there ( I assume )....which one is the K40 Relay and which is the N10-1.

Luckily I also have another W210 at the moment so I can swap and change parts around once I've identified the parts.

Many thanks for your help by the way, its been most appreciated
