Even before these past few weeks of very hot weather, my wife complained that the air con in our RS6 is not very effective.   She then gave the car to Kwik Fit for an MOT and asked them to check the air con. They did so and reported that the problem has two different likely sources.     (1). Required replacing a cheap part.    (2) Required replacing an expensive part they they didn’t think that they could obtain easily.    Therefore they suggested that we take the car to an air con specialist.

Anybody got any comments on the above ?  

Hello Steve,

I think there were quite a number of posts about air con. issues associated with a ‘pressure sensor’ - possibly vacuum sensor, which seemed to solve a number of poster’s problems.

Probably well worth having a search back.

Kind regards,

Gareth,
