Anyone know how to reset the outside temp reading for an S4? My car consistently reports temps about 16 degrees warmer than other outside sources (ie. banks). Your advice is appreciated!

Amount of time at a certain speed for the sensor not to be heat soaked from its surroundings. RTM, I believe it's in there.

When I have been driving for at least 5 mins.

I did see mention of the outside temp gauge in the manual, but unfortunately it focused on stuff like the icy road warning.

I've found that my temp gauge shows very high readings when I'm driving and when I'm parked, so i'm at a loss as to what the issue is. I'm hopeful I can just reset it, maybe by VAG-COM?
