HI<br>I have a 2002 S60 my engine light has come on for the first time since I have had this car (it was may dads car b4 me) the car drives exactly the same, doesnt use any more fuel nothing is different. However the check engine light is on and has been on for the past 3 days. I have done a little research, checked the gas cap,oil, took out the sparkies and cleaned them, but still the light is on. The only this that I did do was park my car in high grass, now I understand that the check engine light can also indicate an emissions fault. Could I of tripped something off? I am think maybe grass against a hot exhaust wasnt the brightest thing to do. Should I consider undoing the battery to let the computer reset? Any advice would be great. Also how long should an s60 take to warm up from cold? is it normal while driving on the freeway for the temp gauge to drop under the middle?<br>or is that maybe my problem a dodgy thermostat? <br>thanks Alex
