Should be able to check inlet tommorrow and i have checked turbo at inlet side it seems fine and yes it has dpf with fuel cap sensor but it could have been mapped out.
My list of things to do is replace cleaned egr with a blanking plate included. check turbo oil flow and check condition of inlet manifold.

If all is well i will leave blank in egr and run it for a week or two to see how it goes.
If i suspect debris and carbon build up i need a modified oil feed pipe and new strainer then run for a bit and see.

Does this sound a good plan?
Thanks again for all your help and info
Regards Brad
