ok, so it seems like everytime i drive my car lately the coolant light starts blinking as soon as i start it up. it beeps for a while and then keeps blinking for like 15 minutes, then goes away until next time i drive it.
I have checked the coolant level its fine, and the temperature runs perfectly in the middle of the gauge. How come its blinking? i even pulled codes with the vag-com and there was no codes on there. Anyone have an idea whats going on??

 

If you're certain that everything is good, then it's probably the sensor.

 

check the sensor above the bottom radiator hose

 

ok. i will check that sensor on the bottom hose.
whats the difference between that one, and the one on the back of the head?
I know i have enough fluid and its all good. Im thinking it could be related to some junk left over from when my oil cooler was leaking into the coolant. I had it flushed out, but i think there could still be some residue on the sensors messing things up. I just didnt get why it makes the light go off, but there is not a code, then again i dont get why there is the two sensors, one on the coolant flange, and one on the lower hose?
