Have been having trouble with my '00 Jetta 2.0 A/T w/ 98K miles. Had the water pump replaced @ a year ago (for the 2nd time, the 1st replacement died after <15K miles.) The car has had issues with rough idle when started, especially with a cold engine, since before the 2nd water pump. I've replaced the coil pack, thermostat, and coolant temperature sensor in the recent past. The gas mileage sucks, and when it's idling rough it will stall if the gas pedal is pressed with 30 secs. of starting. Otherwise it seems to run fine, with no check engine light...until now.
It's now throwing a P1296 Cooling System Malfunction. I have noticed the temperature gauge fluctuates instead of staying around the "middle" since the water pump replacement, and will run "colder" in colder weather.
Some research online says thermostat OR coolant temperature sensor.
Does anyone know if the rough idle and the cooling system malfunction CEL could be related? Any recommendations for a fix?
