Does it do this first thing when its cold out ?? if so, fill the coolant res to the max line when cold, if light still comes on, it could be either the coolant leven sensor (my guess) or the temp sensor for the engine- these are known to go bad every few years

2003 vw 18.t temp lights goes on but temp gauges read normal


If your coolant overflow is bubbling then regardless of what your gauge says you are having overheating issues. If your coolant is missing with no aparent leaks then you need to check your oil for a milky consistency and apearance which would most likely point to a blown head gasket. This would also explain overheating. Hope this helps

Temp. gauge don't move past half on 1996 VW Jetta


Sounds normal. If the gauge moved further over, it would indicate an overheating problem, wouldn't it? Check that engine is at normal operating temperature after it warms up. If it is running too cold, your thermostat might be stuck open.

Temp light flashing after starting.outside temp.-17


Extreme cold weather is causing coolant to contract and fluid level is reading low level ... After starting with the engine warm the temp light should go off due to expansion of the coolant ... Solution: Add a small amount of coolant to compensate for cold weather contraction. Good luck!

Car temp gauge/heat


TDIs can take a while to heat up in cold weather. Sometime 10 minutes or more.

If it is taking longer than 10 mins for your temp gauge to hit 190, you may need a new temp sensor, which is pretty cheap and just pops into the engine block, almost right next to the battery.

My mechanic in our town did a quick computer check. Car computer indicated a low level of antifreeze, he topped it up, cleared all messages off the car computer and said to watch the the heat guage for any further irregularities. I'll keep an eye on it, love the car, great mileage fun to drive.
