Looking for the best engine guru for help to stop our madness.
We have a MkIV GTi that we track. Lately it has been giving an overboost code and goes into limp mode, It is a stock AWP with a K04 turbo and a stage one APR tune.
It generates 24 lbs of boost and will run for a while and then randomly go into limp mode. We get and overboost code, P0299. A quick reset (master switch on and on) and it is fine for a while. I can't figure out what sets it off. We just want consistency. Also this time a brand new stock VW turbo relief valve got two pins holes in the housing after running an hour and lost a lot of power...took us a while to figure it out. Help
