Have any of you experienced issues with your Q7's air conditioning system? My wife's 2017 Q7 all of a sudden starting blowing ambient air. I initially thought maybe it was a setting issue, however, after trying everything (Max A/C, recirc, coldest setting, etc) still no luck? I am probably going to have to take it in (dealership is a couple hours away) but thought I'd ask.

Oh, I forgot to mention.... there is a unusual slight hissing coming from the vents when "a/c" is initially cycled on.

I'm going to put my question here as it is a general discussion of the A/C:

Today I turned the heat on, the red light comes on the A/C button. I intended to turn the heating off as the engine was not warm up enough and pressed the A/C button again. The light turned off but the fan was still blowing. Honestly I couldn't find anything in the manual. Did I accidentally find the outside air switch or what? Thanks

Curious as to the resolution to this issue (AC blowing ambient air). I am having the same problem, I brought it to the dealer, they replaced a "pressure switch seal" and recharged the system, but it is happening again.

thanks

I realize this is an old thread but any insights on this ?
