While driving back to Wyoming from Idaho yesterday I pulled out to pass and punched it and suddenly lost power and had to pull back in. ***? I noticed 0 boost and then negative vacuum on my recently installed gauge. Very slow trip home, down to 15-20 mph at times on the passes. Went straight to TDI club forum when I got home and discovered "limp mode". Turned the car back on and my turbo is back of course. All new to me. I have an old MB Diesel and a 12V Cummins and assorted tractors without any modes but wide open balls to the wall! Mine is a neglected 2002 5 spd wagon with 250K miles which I have brought back to life in the past 6 months with a Malone 2 and new injectors and it has run perfectly, very fast and 50 mpg. Iv'e done all the usual fixes and maintenance like manifold cleaning, egr fix etc and this set me back emotionally. I see that there are many possible causes but my question is what is the MOST LIKELY CAUSE given the limp mode was triggered by trying to pass in 5th gear? So far I have just checked the vacuum tube to the actuator. Hooked up and visually OK. Actuator seems to move freely. This has never happened before and I have done a lot of throttle punching so what is the most likely cause and what checks should be done in sequence? I hate throwing new parts just to see what happens. I am starting to lose my love for this car because this is a very dangerous problem.
