600 SL V12/M120 help!!!

[dstephanou]

I have a really nice 600 SL 1993 and it suffers from the dreaded engine bay cracked wire syndrom which has made the car go into limp home mode the ASR light on the dash is on, a merc man came with a diagnostic machine and told me my ASR unit was nackered.................... my question is I also have a working 600 SEL 1992 does anyone know if the ASR unit is compatable so I can change them over and where is the ASR unit?

Repairing the wiring is the first thing to do, you might not really have a bad control box. As for swapping control boxes, the electronics might be the same but the programming different.

What he said ^^^^^

Engine wire harness is expensive but not difficult to install. It will also greatly add value to a car that is not working very well.
