Depends on quite a few things but mainly how it's driven. Not a hard job to remove and check, possibly a "nice" little job to do over the Christmas break.

Mine's done 140K and is still functioning exactly as intended. Mapping out the EGR does help. Of all my cars, the DTi is the one 1 drive the least gently, it seems to go better if you don't let it dawdle about too much.

I had it remapped & egr sorted about 18mths ago. it was de-coked then. I agree about not dawdling I do push mine . if I remember the injector pipes need to be removed to get the manifold off.

If it was properly cleaned out fairly recently then unless something drastic has happened to cause a load of crap to get into the intake, then, with no recycling of exhaust related gunge I wouldn't bother to look for about 10 years, maybe more, if ever.

The last MOT smoke test on mine was 0.33 as a guide so if yours is similar then it's pretty particulate free so really no need to worry.

I just had a look & all that I got was the actual M.O.T no info on the smoke test. also checked & manifold was cleaned July 17. will be ok .
