That's figment, btw.

I don't know if the troubleshooting my Indy did built up some carbon or now with all the fuel going to the cylinders instead of leaking out at the IP its easier to burn carbon out. Either way on the way home it ran great.

If the high pressure to one or more injectors had been being sapped
for awhile then atomization would have compromised, and there easily
could have been carbon build-up.  Based on the symptoms it sure
sounds like what's going on.

The 240D has never belched smoke like that even though when I got
it it could hardly move and I've flogged it hard ever since.

Every Mercedes diesel I've ever owned (12 or 13 of them) would occasionally belch a black cloud after being driven gently in the city for weeks or months or after idling for a LONG period.
