G12 Ambient Air Temp Not Reading Correctly

The ambient air temperature for my G12 is not reading correctly and seems to be reading a higher temperature than it really is. Yesterday it was around 81°F, but it read 90°F. This is admittedly a champagne problem but the issue I’m having is when my car preconditions in the morning it thinks it’s 78°F when it’s really 67°F. I run hot so I like colder temperatures but when you’re just wearing shorts and a t-shirt, it’s already 67°F and you hop into a car that’s even colder than that, it’s quite a shock. Not sure when this issue started but I did read that for some BMW’s the ambient air temperature is around the lower part of the front bumper. I’m not sure if that’s the case with the G11/12 but I did install a front splitter a couple of months ago and I’m worried that I may have damaged the ambient sensor in doing so. Or is this a common issue with G11/12s? Any information would be absolutely appreciated!!
