Is there a diagram of 1.4 L turbo intake system? Also what is the symptom of the pink diaphram malfuntion. Have a P0299 code that sets sometimes when idling or under load ( light or heavy) and mild surging sensation also. Have checked and can see the pink nub in pcv hole on the intake. And does anyone know the voltage on the tcv ( turbo control valve)? Thinking it might be malfuntioning. Have checked the waste gate arm that shows slight wear but doesnt seem to be sticking.
