Hi all, have a 2004 A4 S-Line.
I am sure the air con needs regassing as when i put it on low its not very cold, colder than ambient but not as cold as i expect.
However if i press the centre fan button it goes colder? is this normal?
Also after using the aircon or having it on econ, when i turn the car off it makes a loudish whirring noise like a jet plane engine shutting down, it this normal?
Cheers in advance.
