90% of times is turbo, white smoke when engine is cold and for a few seconds or some water on exhaust. And when is very cold the combustion of diesel make white smoke .

i get it when its warm engine aswell mate

the file is 100% off by switch on every car

customers wont pay until smoke disappears

any idea how to flush it out?

thanks

A PI can make a white smoke "diesel badly burned", but if ur file is working 100% , check the turbo and the EGT . if u get a high EGT maybe the car still regenerates .

Allmost turbos after some km consuming some oil .

But when the cars make white smoke , smells of burning oil, or diesel burned badly? the diesel burned badly irritates the eyes.

Hi,
looks like mechanical problem on engine.
Check turbo and injectors

3.0 TDI?
Your problem - injectors.

I have the same problem. After 9 months, began to smoke Sprinter 906 311. Only at idle. Removal of the DPF correctly on other machines no problem. The solution is not found.

its a 2.0 tdi. is there any chemical that will flush turbo

any1???????????

i think it`s not turbo, white smoke is similar for too much air or less fuel, check for injectors correction on vag (on idle).
does car goes in limp mode after 70-80mph? does accelerate good or badly? check turbo pressure with vag on 3rd gear after 3000rpm (referent and real) check MAF value (maybe maf sensor sticking on high value), maybe egr stay opened,
there is no chemical for flush turbo, only tke off and put in big ultrasonic cleaner or clean by hand, but i don`t think it`s problem with dirty turbo, it will be clean after 5min of hardly drive.

i would check the turbo mate.but ive had a few turbos were the oil seals go,andl it burns the white smoke......common as mud on v.a.g cars.

oil dripping from the pipe on turbo is a good sign,

I Had this problem on my Corsa C 1.3cdti, but only sometimes white smoke, after a change injectors all ok. See does spent oil if spent 99% is turbo

read somewhere that they have issued a recall on the diesel injectors that causes white smoke and rough idle...cant remember where phone local stealer to see if vin falls in range???
