Right I checked and it does have a cable on the egr so I gusse its a euro4 engine. Don't know if this helps diagnose the issue.

This weekend ill reset the ECU and see if that does anything, no got my hopes too high though.

I'm gona have a play with formidable aswell. Seeing as I have a Euro4 it should work for recoding the injectors all though I think ill need a different lead.

Also need to do a leak off test myself just to double check ...

Cheers for all your help guys.
