Suddenly car has a rough idle and up to 2k revs (then all good/great even) and AC has stopped working. Emissions and fuel economy normal. Problem seems to be since new throttle body fitted (plus other bits like EGR, oil pump, coils and sparks). Can’t recall as all this happened while hardly using the car, during lockdown. Just spent £400 at the garage and no joy (not been on VCDS though). Error code P2279 at the mo but apparently no air/vacuum leaks. Suspect the new TB is using invalid parameters and needs configuring properly using VCDS (have read ecu can turn off ac compressor when it reads airflow issues). Happy to pay/buy beers - just need someone in Cornwall who has VCDS and fancies helping out (please)?
