so since i got my vrs wrc i have been having a recurring fault and engine management issue. keep getting the above fault code and blippy power delivery. have read numerous posts and i'm wondering whats the best option is to fix it? n75 valve keeps popping up as does - Pressure Drop between Turbo and Throttle Valve (check D.V.!).

Has anyone experienced this or have a solution to it?

 

thanks
