Cheers Freddy
Just missed out on that one though.
Update on the problem is that all seems fine again now!!!
Went back to it the following morning and had a fiddle with the wiring which seemed a bit untidy and loose. Realigned the TB with vcds after and then tried to reset the fault codes. This time they reset and my car then started up fine again? Not sure what to do now, may still buy a new TB as there must be an underlying problem somewhere.
Car still sounded a bit rougher now than it did but we think the cam follower could be the reason for that. I've not long had the cam belt done for the second time as the car has just passed the 80k mark so we're going to change the cam follower this week.
Cheers for any help given, or for any ideas what to do now. Can't see that the problem has sorted itself and it is bound to reappear at some point...
