POWERSTROKE
Top Post Dawg
The vacuum can is in good condition and adjusted properly. About two months ago I went into limo mode, and it was from overboost. I believe the vanes are slightly sticky. I started to drive more aggressively and it seems to have gone away for a couple months. Took several 1000 mile round trips. Car was running like a top doing 70-100mph on a 800-1000 mile trip this past weekend. On my way back home I felt it go i to limp while accelerating in 3rd in a traffic slowdown. Restarted the car and was fine for the rest of the 160 miles back. My question is what is causing this very random and far spaced out overboost. I could drive aggressively now for two thousand miles and it could be perfect and then boom. It happens. 2002 Golf tdi.
