No heat at idle after some soft of coolant flush/drain/change/treatment? Here is fix
#11
I just started replacing my core yesterday. I did flush several times over the past year or two, but now I can smell coolant when running heat and the windows get foggy very easily, both signs of a bad core. So, I said what the hell. Turns out, it's not very difficult at all to disassemble the entire dash, but it does take time. If you have a little confidence and aren't afraid, it's not so bad.
I'm waiting for the new core for ECS tuning, then putting it back together may be a different story.

BTDT...well, I did the AC evaporator anyway. Too bad about your core; they are usually a low failure item.
Agreed about the difficulty. Lots of parts, but not really a terrible job. Following Bentley makes it much easier.

Here are some things you'll need:
1. A warm garage that provides room on each side of car.
2. A shop to discharge your AC
3. New coolant to fill when your done
4. For tools, you'll need a ratchet set, Allen set, triple square set (or whatever it's called)
5. Patience
6. Plan for a good three to four days without your car.
Enjoy it!

how did you do this exactly, as far as pushing coolant through with compressed air.

Hi - I just bought a 2002 allroad and the heat worked when I test drove it. Yesterday when I was trying out the heat to see how it worked, it was blowing only cold air. I have the heat setting all the way up to high and the car was idle for 20 minutes.
I then shut the car off and let it sit for about 40 minutes, then started it up and it blew heat for the forst 30 seconds, then cold again. Does this sound like the air pocket issue above? The coolant was replaced when the car was services just before I bough it.
Also, do you happen to still have the photo mentioned above showing the bleeded line? I think I will try bleeding the line first.
Thanks!
