EPC light and Traction control light + limp mode

[Connorg115]

So I first noticed problems when driving and the car was lurching from time to time when setting off ( tracton control light was on and EPC would come on and go out)

After a while car went into limp mode with both lights staying permanently illuminated, turn the car off and back on no codes until you start driving or rev the car high.

Car runs perfect until the lights come on and which point idles raises to 1000rpm and sounds like it is running on 3 cylinders (however its not becasue the engine is visibly smooth no shaking

I have VCDS lite at home is there a way i can use this to help?

Sounds like maf sensor to me. Check its properly plugged in and try unplugging it, see if it runs better.

Problem sorted, dirty throttle plate, cleaned and now running perfect

Full boost no limp mode or lights on dash, result!
