Shaking

[stu126]

Hi All

I have an Audi A3 8V, since getting my turbo reconditioned its started shaking, it holds back then lets me go faster, ive had the mass air flow meter changed and the boost pressure sensor and valve changed, it sometimes goes into limp home mode, the error coming back relates to mass air flow, would anyone know how i could diagnose the problem or know how to fix it, theres no lights on the dash when it shakes.

You've do e a good level or diagnosis. And maf sensor change made sense. Have you considered an issue with the lambda sensor?
