Hi,

2005 X5 3.0D. 55,0000 miles Owned from new, full main dealer service history. Recent intermittant errors, fuel injection system / transfail safe. Either would not start or would start and run perfectly. Full and lengthy diagnosis by indy and then main dealer tracked to BUS errors traced to DDE. Finally replaced very costly DDE (Engine management unit). I have the old one by my desk.

Picked up today, and so far....it's back to normal but it will need a good thrash to teach the new unit who is boss!

See "3.0D Replace ECU" in the main forum for all the gory details.
