Thermometer/outside temperature gauge not accurate
I just picked up my car 5 days ago and the first thing I noticed that did not work as should is the outside temperature gauge. I'ts 4 to 5 degree's off and while most people probably could'nt give a crap it annoys the hell out of me. Does anyone know if it can be adjusted? Also my widshield broke within 24hrs of owning the car. Maybe I should have kept the xA.
As the probe itself isn't really exposed to "outside" it is reading correctly. open your drivers door. About mid way up in front under the weather stripping it the probe, it sits under the stripping against the body. It's nothing special, just a thermocouple. You can't adjust it.
If it is anything like my Corolla, it is not the sensor, but the location and differences in temp. My Corolla has the same thing, but the thermal variations are too great to really say what is accurate. It is a black car, so a few minutes in the sun and it will read over 100. On average, my Corolla tends to disagree about 5 degrees depending on the location of other thermometers. Five degrees is pretty small variation, I really wouldn't worry about it. Try a thermometer in the same location as the sensor and see what it reads.
BTW, if that five degrees and little things really do cause stress, look into OCD and hypertension. Catch it early before it ruins and controls your life. I had to make some slow changes in my life to get reduce it. There is a lot of anger and stress in your posts, lol.
