I have a 2005 c230 and we recently took it into the dealership for service and when I got home I was reading the diagnostic report and it said "Error B1029 - Unrelated". I wanted to know what that error code was?? Thanks for any help.

 

I believe that it is a CAN communication error.
Between which modules and under what circumstances I do not have the information.
Presumably it showed up when it shouldn't.
