I’ve been having soot covering the front half of my engine ! Seems to be either mostly at the egr cooler to egr valve flange or the spring on the egr valve .
Any other possibility or ideas of the cause? Just started not long ago. Its a ‘09 335d
It has 160k. Oil change every 5k
Intake was blasted at 98k
No lights But will get turbo under boost if I step on it to hard but even that is a intermittent light . I believe that will be the pressure boost control valves in the end.
Not sure of any other info that would help
THANKS 🙏
