Hi, I think I'm having a similar problem as you are. Mine is a 99, and whenever I turn on the car and start driving, the coolant light beeps 3 times and flashes for about 5 minutes. It goes away, but sometimes it'll come back and beep another three times at me. I have not a clue about cars, but I had my oil changed last week and he says the coolant levels and all other fluid levels are fine. When you took the sensor out, did the problem cease?

It didn't stop the problem the darn thing still beeps! I don't know what else to do. I even put in some of that powder that is for leak and so far it has not beeped in two days. So i don't really know if that has solve the porblem. I do know that for where I can see it does not seem like it may have leaks, but I'm getting a little despret, so I'm will to try anything to make it stop.

vw doesnt make 97 beetle. only 98+

could be the ect (coolant temp sensor) its a blue square 4pin connector on the coolant flange under the oil cap on side of cylinder head. THey most commonly go bad.

with the engine running check to see if there is any coolant flowing into the resivour. If there isnt any flow than your water pump is faulty.

However how do I check to see if the coolant is flowing?

Get the car up to operating temp. and put your hand on the upper and lower rad hoses, If coolant is flowing they will be hot , if not the upper will be hot only next to the head and the lower close to the thermostat housing. The little spherical tank up near the firewall under the pass. side fender is your coolant overflow and reserve tank. There is a hose coming in to the top, check for a colored waterfall. (don't open it hot !!!)

I just had this same problem , the plastic waterpump impeller was in many pieces in my case. It is driven by the timing belt so prepare for major work.Buy an aftermarket pump with a cast iron impeller and a new timing belt and belt tensioner if you are really rich(I didn't change mine)
You need a special tool or circlip pliers (good ones) to reset the tensioner) Get a manual like a Haynes because the job is much better accomplished with pictures and instructions, I was under the car for 7 hours.
