Has anyone got any experience with a pcv delete on a audi 2tfsi petrol b7 .

Thanks ,I have not had it gased. this morning the temperature reading was minus 9 ,i have read posts that the ambient temperature sender sensor might stop the aircon working if faulty.

Just purchased a A4 cabriolet and the aircon doesn't work also the mgs is reading - 9 ,i have read it could be the ambient temperature sender sensor has anyone got any thoughts, it's a 2tfsi 2007
