What hapend is the obd2 cpu set that back to defalt. but usually when this happens the outside temp is incorrect and keeps on changing. what you need to do is go to the dealership and tell them whats wrong, they will put there cpu up to that and correct the problem, i never heard som somebody doing it themself. But...is there something on your room like an cd antenna?? this will throw it off compleatly!!!
