Hi all anyone that could help now my engine management light is and won’t disappear with a code read now it’s telling me that the mass air pressure high in the intake I’ve changed the sensors could any one help 

Welcome.

I flagged so a Mod can move to the Mk2 section and hopefully someone can help. 

Check that the oem dump valve (recirculation valve) wiring is ok and it’s actually working you might be getting pressure surge because of that, also check the turbo wastegate is working and not holding boost so your getting more psi than you should I think it’s controlled by an electronic solonoid the wastegate
