I have a mk7.5 Golf GTI. The air conditioning doesn't work (it doesn't get cold, the blowers do work fine though), I was wondering if any of you had any ideas? It's still under manufacturer's warranty too. Symptoms: I press the physical A/C button and the little LED light on the button does not illuminate (the A/C icon in the infotainment screen on the temperature control page does highlight as checked though if the button is pressed). I have checked the F7 fuse for A/C and this is ok. When VW looked at this issue, they said the high pressure gas was low so that's why the air conditioning is not working, so they recommended that I service the A/C unit. I have had the high pressure gas filled by an independant garage and I replaced the pressure switch (which is usually the cause of non-working A/C apparantly), however, I'm still in the same place as the start? From my searches it doesn't seem to be a common issue? Any help will be appreciated.
