weird temperature control

[Nuccadoc]

Just wondering if anyone has had this problem before?

I have my temperature control synced, meaning, both sides are at the same temperature. When both on LO, everything is just fine, but today, as it was a little cooler out (8 degrees C), I turned the knob to 19. Noticed that I had cooler air coming out of my left window vent and out of the left center vent. The right center vent and right window vent had warmer air coming out of them. The right vents seemed to be the right temperature I selected, the left still seemed quite cool.

Brought this up at my first service, and they didn't see anything. It was warmer that day. Notice it more on cooler days. Anyone else have any of these issues before?

I'm having the exact same issue. What was the cause? I have a 2013 S4 as well

Was the sun glaring into your car from the left? The sun sensor compensates for the glare and if the glare is only on one side of the car it will blow cooler air on that side.
