    I have the same problem with my 02 jetta 1.8t ... im pretty sure that it just means that the engine is too cold.. after the car warms up for a little while, if you restart the car it should shut off.

Its most likely the ETC sensor. Its located on the side of the head on the cooling flange. Very easy to replace just unplug the wire and slide the clip out of the side. You can get one from VW for about $25. Make sure to get a new o-ring with it.

I did a oil change and spark plugs on my 2002


that happens sometimes dont worry. As long as the light isnt blinking it is fine. Just drive it for a few days. If it doesnt clear itself, take it to a shop and have then clear it for free or cheap. You could also disconnect your battery for 15 minutes or so and it will reset the computer and whipe the check engine light off. Sometimes if you have a bad plug or all cyclinders arent firing it causes the check engine light to come on. now that everything is replaced just do what I said above.

I have a 2003 VW jetta tdi


You've lost engine coolant somewhere, and need to fill the engine back up with the VW special G12 coolant.

Then find the leak, which will be in one or more of the following places -
Water hoses to heater core, including any other coolant carrying hoses in the engine compartment
Radiator hoses
Plastic manifold bolted to side of engine which is known to leak (have replaced on an '01 VW Beetle, and an '02 Jetta, both members of our family in the past few years.).
Overflow reservoir cracked
Radiator leak.

Reply back what you find. If the engine got too hot, you may need to have the thermostat replaced.
