ducato 2.0 jtd still running rough ,so decided to drop it off to a friends who live close to the dealer i bought it off as the dealer has now had a quick look and said hell connect up to a diagnostic machine tomorrow . but on way to friends, ducato is now also reving extremley high, knocking and belching out black diesel fumes even though i am not depressing the acelarator pedal, if i turn off and restart shes ok again apart from the feeling of misfiring , i had a similar problem with a rover tdi it turned out to be the ecu ,any ideas.
 
just found out engine oil level is about 2 inches over the full mark apparently this can cause whats called a runaway diesel where the engine revs out of control which is what im experiencing , but would this also make it run rough generally?
 
Can be very bad.

The engine runs off the oil, and burns it. So yes, it can cause rough running.

It's worth doing an oil change to start with, but then you need to check if the oil has been overfilled, or if the oil increases.
I don't know your engine that well, but in others, diesel can leak into the sump through various faults, and causes the "overfilling".
 
Definitly sniff that oil to check for diesel one of your injectors might be dumping diesel into the bore.
 
have just changed oil there was two and a bit of 5 litre oil cans that i took out just over 10 litres, only supposed to be 6.25litres , changed the fuel filter, cleaned up the egr valve ,and ran some more injector cleaner through her with fresh diesil, she is running better now ie no longer running away revs wise ,but still fluffing/misfiring on pullaway and lacking power.gonna keep eye on oil level if it increases il know its dumping diesel into the sump.
