Hi, guys. I am getting a grinding noise when i start up in cold weather around -15 C. It goes away after it warms up but the engine will sort of have a faint knock here andthere when idling. Sometimes it lasts just a few seconds sometimes up to a minute. It will appear every couple of minutes and the stop again. Wondering if it may be the water pump. Also i can`t get my oilchange reset light to turn off. It comes on for a few seconds everytime i start it, not a huge deal though.
