So i have been away for 2 weeks and now that i'm back i took the car for a ride, and guess what ? The smoke is still there, present like a shadow ! And i am very worried, because i have told you that when the temperature rise above 10 degrees C (50 F) the smoke does not see, and now outside there are 16 degrees C (61 F) and still smoky. I guess my problem got worse.

Hy guys. I don`t want to be rude or something like that, but as you are all is220d owners (or former owners) with more or little experience in this car, can you take a look on my problem in this post. I am open to any suggestion because i am very sick of this white smoke.

Hy everyone ! Sorry for the late reply. Finally i got the additive and no luke, i still have the same smoke coming out with the same symptoms. Now i have to try the DPF foam cleaner from Wurth witch Shepherd suggested. In the meantime the weather is getting warmer past 10 degrees celsius, and the smoke will not be visible anymore, this will not solve the problem, but it will be very hard for me to know what is happening if i can see the smoke. If you have any other suggestions i am very open for everything.

Ok. Thank you .

I check all over the place but i didn`t find this additive, so i make a order on Ebay, it will arive in 1 week. Until then other suggestions ? I am open for everything.

Thanks i will check it out.

Hy guys ! So i have done cleaning the rubber hoses and the problem is still there. No change whatsoever. What should i do next ? I am very stressed about this problem.

Ok. I will try this firt time in the morning.

Ok i will do that, but the rubber hoses go in some metal pipes, do i blow air in those pipes as well, or just in the hoses ?

ok. I will start searching myself. I searched like crazy and i didn't find anything

ok. I will start searching myself.

I made some pics. The first one i guess is the differential pressure sensor with the rubber pips, if that is true it means that the "pressure regulator" is somethung else, located between the engine block and the rear wall. How can i cleen the sensor ? I have to go to the service or can i do it myself ? http://imageshack.com/a/img34/5374/dky6.jpg http://imageshack.com/a/img600/6522/kqft.jpg http://imageshack.com/a/img203/8985/gxcg.jpg

As you probably guessed it i am from a country that is not a nativ english speaker, so i might be wrong about some tehnicall terms like the "pressure regulator", this is why I asked above if the "differential pressure sensor pipe" is the same with "pressure regulator". But i will take a look and make some pics to put here. In other order of ideeas i have cleand the EGR valve. Now my MPG is between 18 to 20. I have see the diagram and i guess that is not the same thing ("pressure regulator" - "differential pressure sensor pipe"). I will put some pics soon.

Guys thanks for the advices ! I am glad that someone have am ideea about this problem, so far it was like an alien problem, every body heard about it but nobody knew how to resolve this. I will take it by steps. To start with i will go and see what is with this differential pressure sensor pipe (by any chance the "differential pressure sensor pipe" is the same with "pressure regulator") it is blocked or not. Second i what to try the cleaner additive for the DPF that "Shepherd" recommended. Thirdly i whant to see if my injectors are working properly (i guess there is a method to check that). Now i have some questions : how do you clean the dpf filter, is this a process that you can do it yourself or you have to go to the service ? How do i use this DPF ceaning additive, like a normal fuell additive, i put this in the tank with full diesel and i go for a long drive ?

This occurs when i accelerate even at low speed and when i stay at triffic lights or stuck in traffic jam. I guess it happens more at high revs but at low speed. If i accelerate hard for a short distance and then i stop at a traffic light for example until it turns green i am covered in smoke.
