c200

Hi i am new to this club and just got my 1st merc after owning a bmw, i got it off a mechanic who tells me its had lots of tuning work done, its a c200 cdi and its had a c220 engine dropped in it, its also got a larger intake manifold than standard, had the dpf removed and remapped and beleive me it is very quick im also running it on v power diesel, my question is that when i floor it there is a large cloud of black smoke is this normal ?

I personally thought the 200 and 220 engines were the same with different software, only the 250 upwards being different

Black smoke may be the fact the DPF is removed? Not sure how that removal effects what's visually coming out the exhaust

thanks for replying it had that engine cos the old one died, allthough i am the shop floor manager of a bespoke exhaust company ive never owned a diesel car, we have removed dpf's before but somebody else has done the rest of the work

220 and 250s have twin turbos on the w204s, but the same basic block. Not sure about any other differences.

black smoke = unburnt fuel, map overfuelling, may be worth a rolling road visit for a decent tune, as mentioned, dpf removal isnt going to help either.
