Outside Temperature Sensor

[JW2020]

Pretty much since day one I’ve had issues with the temperature being incorrect, often off by multiple degrees. It appears as if the temperature is between 65 and 75 it’s fairly accurate, but when it’s really cold or really hot, the temperature reads 10 degrees higher than reality. It’s really annoying and the dealership has replaced the temperature probe 3 times now with no success. Anyone else experiencing something similar? Hoping there’s a fix or resolution to this. Thanks!

Your outside air temp is going to be off around 5 degrees if the cabin temp is a lot different than the outside environment.  The problem is the cabin air gets pulled into the mirror due to pressure differences.  Cabin air mixes with outside air and you get a delta.  There is not a fix out there for it.
