Question about 2000 Volkswagen Beetle
Water pump. water pump. water pump. i am a vw dealer tech and on 2.0 and 1.8t beetles the water pump impeller is plastic, and what happens is usually another component, fans, fan control module (under battery tray), thermostat, fails and because the impeller is plastic with just one overheat the plastic becomes brittle and shatters, pull the water pump out and you will see the impeller in 3 or 4 pieces. replace water pump and make sure t stat opens, fans come on (a/c off) and proper water pump flow.

Had same problem. Taken to VW dealership. Definitely the water pump which has a plastic impeller which had disintegrated. The effect is that the coolant isn't being pumped through the motor and so it overheats regardless of the cooling fans. The pump runs off the cam belt so you it needs to come off to replace the pump.

I took the thermostat off and could see impeller, it looks metal and seems tight to the touch, started and could see impeller turning, hooked water house to rad side and watch water flow out of engine, sometimes it will go for a day or to, but it's happening every time now, any ideas appreciated.thanks Ed

You have literaly described what my car was doing. your burning yourfluid off. the reason thefluid drains when it sits is because it expands while hot.

I had the same problem, 2001 beetle turbo sport edition. I changed the sensors, and had no success,then I noticed the cooling fan not turning on at all, replaced the cooling fan assembly and problem solved. I purchased an after market clone part for 150.00 dlls at a local parts store.
Maybe this is your answer, I don't guarantee it, but check if your fan is turning on after the car is running for a few minutes, remember I changed the sensors first, I am no mechanic at all but I am just trying to help.
