Hi all

I have a Uk spec 2007 E70 30.D

The remote fob which does not have comfort option, will not work. I have tried a new Diversity att, of another model, but the same Part number to no avail
The key works inside to start, and the central locking working when pressed.

Has anybody have any experience of maybe replacing the Key ecu ?
Or any further advice. This is a used motor which I picked up for the Mrs.

Ta
