I have a 1985 Jetta diesel. What I did since the car has no way of bleeding the air out of the system via bleeder screw I parked the car on a slight incline leaving the tank for the fluid at a higher level. I ran the car until the thermostat opened (The thermostat is on the bottom of my engine) I kept topping off the antifreeze. I also kept a jug of anti freeze and water in my car for the next few day. Whenever I got done driving the car and the car cooled off I would check it to see if I needed to top it off. I finally got the air out of it. You could call the vw dealer to see if there is a bleeder on the engine, if so open the bleeder and fill until antifreeze/water comes out, then close the bleeder and top it off to the full level. Just to be safe check the level after you drive the car. Air can still get trapped.
as stated, gotta be the thermostat... when the water reaches a certain temp this valve must open to allow coolant to flow thru the radiator or the water in the engine will get too hot and cause significant long term damage. It's good that you pull over immediately and let your engine cool off. A good emergency remedy to get the car to a safe place or a repair facility, is to run the heater at full blast. effectively using your heater core as a radiator. not ideal but will get a you a few more miles down the road.
Hi Lori . Sorry but it sounds like your water pump inpeller (The internal part that circulates the water) has broken off or come lose . But i would recomend changing the cambelt and tensioner as well . Regards VW Audi tech
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.
