Aircon issue. Wont switch on

[Pando99]

Hello all
Went out in the 2014 RS4 for the first time in 3 weeks.
Switched on aircon and light comes on but goes out straight away as it something is not latching.
Was working nice n cold before i went away
Any one experienced this before, google now really bringing up anything
Thanks

Has it got any gas in it?

Check gas, and check fault codes of pressure sensor

I had this a a few weeks ago on my 2014 RS4, thinking it woudl be what others have mentioned before (gas, pressure sensor etc.). Turns out it simply needed a new switch and all was back in order!
