I have a B9 TDI 190 Saloon. I have done about 53,000 miles and do have the air con on as standard. Today was the first decent weather. With the ignition on, but the engine off, I can toggle the air con switch to show ON, ECO ON, and OFF lighting up. If I switch the engine on, only OFF will display, the others are greyed out. Needless to say, on OFF I can get no air con. I looked in the manual and it mentioned that I need enough battery and fuel to make air con function. As far as I know, my battery is fine, and i'm certainly not getting any warning lights. I was a bit low on fuel so filled right up. Still no joy. With the engine on, I cannot get air con to switch on. I could find nothing in the manual about re-gassing the air con. Stupid question I know, but could it be as simple as that? I have had no warning lights at all come on and nothing to alert me to a problem. Your thoughts would be welcome.
