Ok so i have a 2001 tt quattro and while racing i loose all boost in third gear till about 6rpm's. Boost works in all other gears just fine. Can anybody explain to me whats going on? Stock turbo aftermarket piping and intercooler.

 

thanks for the help

 

The only thing anybody could tell you to do is systematically start at one end and go to the other. Sorry man but that's a very broad symptom. As a troubleshooter there are many different areas I would start but you never know until you get elbow deep into it.

 

see ive checked all the hoses my dv and im about to replace my stock boost controller to an manual one and hope that helps. Cause i went from runing 15 psi to 10 psi sometimes lower. sorry bout being an *** but if someone would have just said that it would have helped.

 

I understand. It's no biggie. I guess something else I was considering as well was the wastegate actuator or intercooler piping but if it only occurs in that particular gear between a specific RPM range then I can't see how that would be it either of those.

 

ya ive got no clue and it only happens when i speed shift. as long as i dont dump the clutch its fine. I think my boost controler is messed up cause some days ill be running 15 to 18 psi and the next day ill be running 6 to 8 psi... any clue?

 

probably going into limp mode. without a a VAG com your flying blind. Possibly bad MAF sensor. Unplug it at the connector and see if it runs ok.

If you have a dual mass flywheel/clutch and

ya ive got no clue and it only happens when i speed shift. as long as i dont dump the clutch its fine

you might be changing that out when it dies........it's fun.
