Baffled here. Got MIL come on. Checked codes and got 0409. Voltage high. So check led egr. Ok. Even fitted another to make sure. Checked loom fronsocketto com. All got good conductivity. So what's next?

The only clue I have is that aside was repairing another fault last week, (non start on the start button) I found 2 completely broken wires in the loom going to the PCM. One acleannewbreak the other had been crudely repaired with a different bit of wire that had broken again. Fixed both wires after sorting the problem I was looking for and then this starts.

As I've rebound the loom I dont want to crack it open again just to see what happens when I re break  the wires if someone has a better idea.

Thanks

Russ
