2006 NB TDI, 60k miles, no modifications whatsoever. Car starts and runs normally.
Climate - Eastern North Carolina, warm and humid.
About 2 months ago I started getting occasional flashing red temperature light after driving 2-4 miles. No apparent pattern of occurrence. Temperatures were very warm day/night. Only once did it flash after the car had been driven any distance, when it flashed/beeped then stopped. A check of the coolant reservoir shows good levels but not all the way to the top. I added approx. 1 cup of distilled water. Light stops for a few weeks. I bought a new green sensor from vw dealer as this forum indicates its only a matter of time with the black sensor. This past sunday I changed the sensor and due to the tremendous advice on this site, using the quick replace method, everything went smoothly. I did add some dielectric paste to the electrical connections before replacing. The replacement was done on sunday. Monday and tuesday no issues. Wednesday evening after driving less than 4 miles the red blinking, beeping warning light goes on again. Stops and does not reoccur during the rest of the trip (short duration). Coolant levels are fine, I added approx 1 1/2 cups of distilled water on sunday due to sensor change so resevoir levels are good. Based on what I've seen on this forum the next best guess is the resevoir being at fault or the probes. I will try the probe scrubbing remedy next. Any further advice/thoughts appreciated.
