Dear MJ50,


Greetings from Ireland.
Thank you for your prompt reply. However for some unknown reason it failed to make it across the Atlantic or so it seem.!!
If you get a chance perhaps you might resend it.
This is my second Mercedes. The first was also c-class, petrol - an alcoholic!.
Mercedes is very comfortable but can be temperamental at times.


Looking forward to your solution.


Regards,

This is what I got from your fault code, if this is the case then I'm not sure why you were changing the sensor in the differential. You guys are working at the wrong end of the car.

Trouble Code:

Subsystem:
