Figuring the car is not overheating because it does it even with the engine cold sounds like a defective level sensor. Like on most VW's inside the reservoir bowl the level sensor is located. First make sure the level of coolant is filled to the maximum line while the vehicle is cold. (not run for a few hours) If that's ok check the density of your coolant. Requires a coolant tester that you can pick up at any automotive store. It should be between -36 and -45 degrees C. (A good mix of coolan and water) Also make sure you use the right coolant. In 98 it should be pinkish red. And get it from the dealer. Do NOT MIX coolants as it could destroy the system. If it is unplug the connector at the level sensor on the bowl and make sure the terminals are not corroded. If they are not before starting he car jump the 2 terminals with a paper clip or wire to fool the cluster into thinking the coolant is full. Be careful not to damage the terminals or spread them. Start the car, the flashing light should not come on. If it doesn't your problem is the level sensor in the bowl. You'll have to replace the bowl to replace the sensor. They're one piece. Not very expensive. You can usually save the coolant in the bowl and reuse it if it's ok by blocking the bottom hose and putting your finger to save what's in the bowl.
