Audi 3.0 tdi white smoke… with new injectors !

[victordu26]

Hello,

My 2006 Audi A4 3.0 tdi had the white smoke problem (confirm with VCDS / out of eange for channel 72 to 77) and I changed 6 injectors with remanufactured ones.
After this, there is less smoke, but still remaining. For example, after coming down a mountain road, white smoke behind the car…
What can happen ? Bad new injectors ? In VCDS they seems to be OK.
Any other solutions ?

Thanks for your help

Usually smoke coming down a mountain while Engine breaking news valve guides .
Could be rich with thin air though

Thanks for your answer,

The smoke is clearly smell diesel, not oil. I also have smoke when accelerating after a red light stop...
Can the cat or lambda be in cause ?
