I think I’d do a compression test when cold as a first step. Check the fundamentals are good.

as above or have the injectors spill tested to see if they are leaking off too much , then its refurb time

Certainly starts with 651, a lot of OM651 injectors failed around that time and were replaced under warranty (mine were as a precaution)

Hi guys sorry for the late update but had the compression test done and cylinder 2 compression was down and the mechanics say it’s either the piston ring or Conrad bent anyone no how much would this cost me to get done

No one could really say until it's apart but it won't be cheap.

Well done. At least it saved any more messing about with injectors and stuff.
