Basically the one thing I didnt replace and ruled out was the Dem as I had it repaired by BBA-Reman. On running out of ideas and faults pointing to it I sent it off to Lukas at Volvo Diagnostic.On opening the unit it was found to have been very poorly repaired .Because the unit was not fixed correctly the can communication was far too slow and their was water damage due to poor sealing.A refurbed unit was supplied but failed to communicate properly(neither Lukas or I understand why) so another was sent and everything worked perfectly.Really annoyed that ive spent a large amount of money chasing the problem.
