Hi Paul

Its a new van to me so I don't know how it ran before I have noticed that the starter is quite sluggish aswell and van has done 220k do these vans 2008 reg 2.2 have a dual mass I've been reading somewhere that the clutch and dual mass dust goes into starter and messes with the Gubbins

It will be a dual mass. i would be pulling the egr valve out and either replace or clean it as it sounds like it sticking open a bit and it will affect the starting

A search on P2635 comes back as low fuel flow. Maybe the fuel filter needs replacing or one of its connections has an air leak so the fuel drains back. If there is a hand primer pump try using this before starting to see if it makes a difference.

 

You could also check the battery voltage, it should be about 12.5 volts before starting and once running about 14.4 volts.
