Hmmm, not really having any of that. Exhaust stinks, but more 'diesel dirty' than rotten eggs, nothing visible.

Acceleration is good, no detectable mis-firing at speed, although it sounds a bit off at idle.

When starting while warm/hot, CEL will stay lit for several seconds. Once it goes out, engine will surge briefly before smoothing out, then run fine. If shifted into gear while CEL is on, engine will stall, but will re-start and then run fine.
