Darrel. I did some digging in the EPC and can't come up with a part # for a K40 relay for your car. It doesn't seem to show up in Group 54.40 (the fuse and relay cabinet on the driver's side) which is where it is in the 210 chassis. FYI, one for a 210 E-Class retails for about $120. Perhaps you tell me where you located it so I can do some more digging in the EPC.
