Cooling System Performance CODE
So I got this code today P2181 it says cooling system performance. I have a 2003 Jetta 2.0 My temp gauge never goes past 190 which is center it in-fact doesn't even get to 190 it just before that. I've replaced my Thermostat last year as well as my coolant temp sensor on the side of the block where the coolant flange is. I've replaces my timing belt and water-pump about 2 years ago. The water pump has only 7-10K miles on it. What else could it be? is there a second Coolant temp sensor? could my water-pump be bad already? Or my thermostat bad after a year? is it possible that I need to change my coolant as It is winter now and getting into the low 30's? could that cause it come on?
Thanks
