I was just wondering if this happens or happened to anyone else and if its a big deal or not or even if someone knows what it is and how to fix it.... Basically when im driving and my car is at normal tempature, I will blast the head (I live in Seattle so its always freezing here!) then I well keep driving and look at my gauges and my temp gauge will drop, so i turn it off and after about five minutes of driving it goes back up???? any ideas? i appricate the help in advanced....

 

your heater core is working as a radiator.. and your fan is helping displace the heat that is on the heater core therefor cooling the temps yadda yadda yadda..

thanks man, should i worry about it or is it no big deal? also it my engine gets WAY louder when the heat is on... should i try to fix somethin or leave it be? Again thanks for the quick response

 

Its really nothing to be concerned with. If it raises or drops rapidly or sporadically I would think youre having thermostat problems, but if it just drops when your pumping out heat that would be a normal response.

 

awesome man thank you so much i appricate it, it does kinda seem like it drops real low but its prob cause i blast it w/ the heated seats on haha.

 

Well.. the heated seats are electronic, not related to the heater core.

 

just make sure your running dead center on the temp guage when your car is at its peak of hotness..

 

Yeah i have and it does i just wanted to make sure. .thanks a lot

 

oh hhaha see good things to know. I am really new to the whole audi thing, i used to have a type r so i have no clue about a4's or audi's in general haha
