Thanks guys yes it's the EGR valve if I can find someone to renew it for around £100 well worth while for peace of mind , it's a Ducato 2007 2.3 only done 40,000 problem may be when I bought it at 4 years old it had only done 10,000 and most diesels do like to work .

an egr valve only works on start up for a limited time it reintroduces exhaust gasses into the inlet manifold to enable a quick warm up of the engine and helps with emissions, if your egr valve is clogged with carbon it will stick and under certain conditions will make the engine cut out,
i havnt heard about using oven cleaner before but a litre of meths from homebase works wonders, remove egr valve pour meths into bucket throw in the egr and leave overnight keep some meths back for a bit of rinsing the following day before refitting, 95% of egr valves will turn by 120 degrees to internally block off this also keeps the electronics connected so ecu is fooled into correct emission status, so if you are stuck in middle of knowwhere and need to sort it out undo the mounting bolts turn it through 120degrees and using one bolt refit.

Unfortunately my problem with EGR valve occur when the engine is well heated up, so should I be looking elsewhere?
Again this has been a great post
Yes i think they open and close quite a bit under different driving conditions i know on my vw lt when i hook it up to my computer it shows its duty cycle. I stripped mine down and cleaned it all and the inlet manifold last month when doing my timing belts also blocked it off at the exhaust manifold. Has been ok no warning lights as mine is vacuum operated. Here is a picture of my valve and inlet at 30k miles not too bad but still a lot of sticky black mess in the inlet manifold.View attachment 23391View attachment 23392

Quite a common mod is to blank the EGR valve using a solid plate.
People doing so report better MPG and power (not massive, but noticeable)
However, with some engines it can throw up the engine management light.
Searching on vehicle/badge specific forums may well yield the answers you're looking for.
