Sounds like your heater hose going to the heater core is stopped up some where along the way, Or your thermostat is broken. Otherwise if there is hot water getting to the core then it WILL blow warm air.

You have a 2000 Beetle you can drive it up to 35mph then it starts to overheat if you slow back down under 40 mph it cools back off what is the problem?

First thing that comes to my mind is that the air fans on the radiator are "reversed" this blowing instead of pulling the air in. To check it: Once the engine has warmed up and the fans are blowing, place your hand on the tail of the passenger side head light (where you would adjust the wind and elevation of your head light) Make sure you keep your hands AWAY from moving parts! If you hear the fans, put you dont feel the air blown toward the inside, the polarity on the fans is reversed andthey are blowing airtowards tha outside. BE VERY CAREFULL WITH MOVING PARTS!
