The heater of the Audi A4 2005 constantly heats up even when the heater switch is turned off?

The Audi mechanic told me this is 'normal'. The heater in the 2005 models constantly heats, even when the heater switch is off, Just doesn't' blow hot air. This doesn't seem like German engineering to me. It function like a radiator and causes the cabin to heat up in hot weather.


Is there a solution to insulate the heat source?|||You could try pushing fiberglass insulation up and around the heater core. Just make sure the core doesn't get hot enough to burn the insulation.





Another idea I had, that seems like it would be a permanent solution, if it's actually doable, is to create a way to temporarily bypass the heater core.





The way it works, a hose brings hot coolant into the heater core, it cycles through the core, then out via another hose. If you were to hook up a 3rd hose between the 2 other hoses, and then place shut-off valves like this http://www.homedepot.com/Plumbing-Plumbi鈥?/a> on all three, you could, with the turning of a few knobs, switch from a bypassed heater core to a functioning one. I have created an awesome movie outlining my idea, and posted it here;

Check it out, and let me know if you have any questions!





Good luck!|||turn the heater off where it's red turn it to blue
