How much smoke is too much?
Hi all...
I know that without a DPF, my 320d (163ps) will smoke under hard acceleration from time to time. Before I fitted my Spider, I used to see smoke occasionally (always more noticable at night of course) and after fitting, initially it didn't seem to be any worse.
Recently though, It seems to have got worse (only under hard acceleration). I know this is not an exact science but the other night it seemed to be really billowing smoke - I almost felt bad for the people behind!!
I'm not too bothered about the actual smoke itself and performance/running of the engine doesn't seem to have been affected - but does it actually damage the engine in the long run? I've done a search and there is lots of info about over-smoking just being a symptom of over fueling but I couldn't find anything to say whether or not it is actually causing any damage?
