Hi everyone
Thanks for having me I'm from n ireland
My ducato has 50 k and have noticed a hunting noise it's hard to describe it sounds like the pump or fuel it is not the normal idle changed a few bits but no luck and no one has any knowledge
Mine also has no modern diagnostics plug any ideas welcomed

Ty for reply will try it had a new one few years back been looking at everything it's not really bad it just makes engine seem slightly uneven I was looking in electrical at pump

Change all filters, air, diesel and oil if it's not been done recently.
Also check for mice nest in the air intake ducting.
Check turbo hoses for leaks and damage.
Then an Italian tune up (drive it like you stole it) for half an hour after getting the engine up to operating temperature
BTW
