Turbo engines are always sooty at the pipe.
Check and see if the plugs are clean. If black, thats an important piece of knowledge. If clean, no mixture problems.
If the cat has failed, sometimes there is a stink, but you would have a CEL to prove it.
So if no cel, sometimes a cat will stink for no reason at all, but not continuously. So perhaps its the fuel.
But to smell it in the cab? I would check under the hood for a self descructing belt or rubber near the turbo, down pipe, cat, exhaust etc.
If a PCV hose has popped off etc, that can cause smells, but not that of sulfur.
