Default soot

hi from england
Is your MB a straight 6 or a v or a v8 twin or single turbo you might expect to get the odd soot mark up the rear but not to the extent you discribe it could be down to a faulty injector or a turbo fault or a blocked air filter go to the exhaust and get someone to rev the engine when hot check that the exhaust is not kicking out a lot of black smoke if it is then the engine is overfueling I dont know how old your engine is or even if it is the latest electronic injection engine what is the engine like for power and economy does it have an exhaust brake fitted and if so is it partially stuck closed in extream circumstances I have known the silencer box to be full of oil and soot but you would only expect this from a worn out engine with high mileage
regards.
