What do you think Chris on this?
I can tell you that i can't beat my car more. I push her to 120 mph EACH day, i go to the dragstrip, make 1 mile race, have JBD à 100% and my car is
at the garage since 3 week for severe carbon build up New head, intake, injectors +++

Your car only have +- 30,000 miles so its normal that you dont have carbon build up. My car run like a champ until 60,000 miles... You can beat it, put whatever you want (tune, additive, etc) you will have carbon build up as soon as you approche the 60,000 miles mark

The mecanical advisor tell me its a bad design egr/emission system and and the carbon build up is inevitable. Its bad, but its the reality.
i am certain that each 335d will suffer from carbon build up before the 100,000 miles mark.
