Default AC Behavior

Hi. I've got a 2014 A6. Now that the weather is starting to warm up, I'm going to try to take on an issue that has been going on for as long as I can remember. Ambient temperature is around 68-71 degrees. Internal temp is set to 73 on Auto and Synced across all individual temp settings. The AC comes on strong, blasting really cold air even though the temperature is close to, but below the settings of the internal cabin temp. This is after the car has been running a bit, just in case anyone might be thinking that it's trying to turn on heat before the engine is warm.

Is there any sort of internal cabin temp sensor that could need some attention? Anyone got any ideas? The car is on extended warranty, so if something needs some fixing, I'd like to get on that quickly. Thanks.

Check in MMI, under car settings for the AC mode intensity setting.

That would have been awesome. But when I choose the AC settings on MMI, I don't have one for AC intensity...

Check this thread on the D4: https://www.audiworld.com/forums/a8-...t-mmi-2986212/ The A6 setup (at least in my car is identical)

My car has that menu and I have 4 zone. Maybe someone that doesn't have 4-zone can chime in on whether it can be enabled via VCDS/Green menu.

I do have 4 zone, but I don't have that last menu choice for the intensity of the AC. I only have the first three...rear cabin settings, recirculation, and footwell temp...

I'm seeing some vague references to it being Prestige only? Either way I suspect it isn't something more than a combination of bits to flip in VCDS in 5F and a setting or two under the green menu. At least that's where I would start messing around (after making a backup scan).

Don’t think it’s a matter of being Prestige as all 4-zones should be the same depending on the market and yours may just be active because it’s Canadian spec. Do you have access to VCDS? Can you post your coding in 5F, 08, & 28?
