Hi All, Not sure if anyone out there knows about this but apparently there is a problem that Audi are aware of with the Air Con Pressure Switch failing on A3's, it leaks the gas from the system so your aircon fails to work. And the parts are on back order, has anyone out htere heard of this????? Or is it just another mistake by my local audi dealership of them just not ordering the correct parts in the first place???????? Can anyone out there shed some light on this ?? Also i have had my radio turn itself off intermitently and the window button to close all 4 windows will only drop them and not bring them back up!!, this needs a new ignition barrell to slove.
