Hope you get it sorted Ash 

Replacement dv could well be the answer.

Cheers mate.
It's going back into Wessex on Tuesday so should hopefully be sorted then but I'll definitely be getting an updated DV from somewhere 'bailey' or 'Forge Motorsport' if they have any suitable.
Hopefully a custom remap after Xmas then as a different DV will mean the TMC box will have to go as they use the same connections.

 
Was woken up at 8:05 this morning to a call from Jamie at Wessex (Has to be the only member of staff that I'd recommend in the place) to tell me that the car was once again sorted.
Great, what was the problem? Bearing in mind I was also told this 3/4 weeks ago.
Split pipe!!  Funnily enough it the 1st thing I told them it could well have been when the bloody car went in a month ago! But No their tech clearly new better and was adamant it was just a loose connector.

Anyways if it is ok then I thank them for finding and fixing it in 1 day with no mention of me paying for the replaced parts
If its not then I suppose it's back to the drawing board.
