Bmw 335i white smoke

[Andymac2215]

Hi my Bmw 335i e93 has Developed a white smoke problem,it hasn’t been bad at all,but seems to be getting worse now,no water problems,or oil use,had the car three months and haven’t had to top either of them up,and still has all the ponies,so not sure about the turbos!!,please help👊🏻👍🏻

White is generally water and blue is oil. Does it start normally with no misfires?

Coolant contamination?

[Saleen836]

Are you only doing short trips? if the engine isn't getting up to temperature there will be excess moisture in the exhaust etc that isnt getting evaporated by heat

My E92 335i does this too. I think it's just moisture in the system taking it's time to evaporate off. Mine uses no oil or coolant either so can't find any faults with it.

I've owned the car for 2 years but known it from new (bought from my FiL) so been around it for a while.

The laws of physics apply, burning any hydrocarbon produces water which (due to the heat of combustion) comes out as a vapour (steam) if you are not using any water you don't have a problem, it is just more visible in colder weather.

Is this only while the car is warming up?

My 335i seems to produce more water vapour while warming up than my older cars, can sometimes still have vapour out of the exhausts after a 10 mile drive.

No water usage or signs of contamination, i think it just takes a while for the exhausts to heat up all the way through and boil off any condensation in the pipework.

If you don't have any other issues and the coolant isn't dropping then I wouldn't worry
