Temp guage up, no heat

I had a strange thing happen yesterday. I was idling and the temperature guage was up about 1/4 way but only cold air was coming through the vents. I was only about a half mile from home so I figured I'd just drive it home and check it there but as soon as the car started moving again it started blowing heat again. When I got home the coolant wasn't down at all. Possibly an air lock keeping the coolant from flowing through the heater core? I've never had anything like that happen before.

Loose/splitting WP belt? maybe your WP isn't pumping enough coolant?
That's a pretty strange one since it just fixed itself

I was talking to my brother and he said he had the same problem with his Scirocco when the heater core was bad. (4c on the chart). I'm going to try to flush it out. At least I still have good heat if the rpm's are up, just not at an idle. At least it's not a big job (I put one in it already about 8 years ago).

If I'm not mistaken, it was the return line to the reservoir plugged. Yours sounds more like the heater core plugged though.

Thanks for the quick reply! Yeah i flushed the heater core with a garden hose and it flowed through okay...I think I'm going to take every hose off and flush it...I kind of think that the metal line from the heater core to the pump is the culprit.
Thanks again!
