Restarted and still kicking out the aforementioned. Now I have emission warning light!!! drove to BMW and they did check and said past fault so did reset for me.

Diesel Tuner said it maybe jumper setting and to move back, but I am reluctant to put back in now to even try. Will the light go off on its own if it's triggered again?

It's definetly the box as running fine again now.

What do you suggest?

Get it mapped instead?
