Hi everyone,

Sorry if I'm posting this question in the wrong forum I just need some help.

So I've just bought a second hand Audi A4 92,000 miles Model 2008 - 2015 range, when I press the A/C button it flashes Red once and then it turns off?, no cold air comes out the vents at all... If it needs to be regassed/recharged would this cause the button not to stay on? or is it something more sinister?

Any ideas?

many thanks
