I have 2010 E350 avantgarde with the straight LED DRL, I have fitted a genuine E63 front end (bumper and wings\fenders), it is all pre facelift. But since doing this the DRLs do work but after turning the headlights on and off, it shows a fault on the IC "left daytime running light malfunction" & "Right daytime running malfunction". I have check the fault on the front SAM and it shows the current draw being different to expected. What do I need to change on the coding?

I have xentry myself, and also have access to online SCN coding through a friend at a local indy.

Any help would be great.

 

Sorry I can't help with the error, but I'd like to see a pic of the E63 front end on your E350
