I used the Carly II for BMW to scan my car because my Service Engine Soon (yellow) light keeps intermittently coming on/off. It comes on, stays for a couple of days and just as suddenly goes off. I plugged the Carly in and I got 2 fault codes - the one that I'm really worried about is this one: Fault Code: 002AD8 ; Fault Explanation: EAC sensor monitoring.

From what I can tell - the sensor on the radiator is bad (or going bad). My question(s): Any idea if this is a BIG ticket item and is it worth fixing? - the car is otherwise in great shape with roughly 148K miles.

This is my first time posting-I tried searching for an answer, but was unable to find any questions for this. Any suggestions/advice welcomed. Thx!
