Ambient temperature sensor
 

I think mine is reading about 4 degrees or so too high. Anyone else's sensor off by this much?

I know in my Audi the ambient temp was tied to the A/C so it will determine how much cold/hot air to pump out. I forgot to plug it in once and it showed something crazy like -10 degrees so unless I put the cabin to "low" it would just blast out hot air and this was in the middle of July in Miami!

IMO the ambient temp on my 2014 varies wildly if even one degree is changed

it's so odd though... Set it to 78 and it's blowing freezing cold air at a high speed... 79 and suddenly it's low speed and "warmer" air. I don't really understand the algorithm they used to calculate it, but doesn't the tech pkg version include a GPS-linked temp control?
