pretty much all sorted now..SHOCKING SERVICE FROM MONDEOSPARES.CO.UK
the seal on the fuel pressure regulator needed replacing, a injector was out of code, and this is the shocker
DO NOT USE THIS INJECTOR RECONDITIONING SERVICE...
MONDEOSPARES.CO.UK from stoke on trent re conditioned my injectors they never re coded them or did a proper job at all real cowboys! and left one of the injectors re assembled and re tightened together finger tight!!! the nozzle was rattling about in the cylinder,
the car is out of limp home mode and fault codes cleared, but there is still some diesel clatter that was never there and a clicking when car comes off full boost
But car is completely use able.
ill get it tuned up and looked over a bit more thoroughly and do all the aux belts and tensioners now
