I think I have found someone who may be able to read the ECU
Just a quick update.
I had the 'car' shipped across to an ex Rover dealers this morning. We put some power to it and the dash lights lit up........ which was a good start. The mechanic then plugged his laptop into the diagnostics port to try and access the ECU. Things didn't go to plan though and he was unable to get the information we were looking for.
Where I go from here I don't know.
I think I'm probably going to go through all the green stolen Mini Coopers for the past few years to try and get to the bottom of this.
I will not be beaten by these thieving criminals and am determined to return the car to it's rightful owners.
