Hey everyone I'm new here, but I have a question. Just recently purchased a 2001 S4. 140,000 miles on it and the car is in mint condition. Original Florida car now it's in Michigan. The heat blows out cold. Took it to work today thinking maybe the heater core is blocked but it's circulating at 160 going in 160 coming out. Has anyone had this problem with this car at all? Is it something common I can check for instead of chasing the problem? Has a APR chip also, man does it fly. Found a few things that are kinda discouraging like a small oil leak, this heating issue, and the balljoint boots are cracked and dry rotted making noise. Not a big deal just didn't have a way to shake it down before I bought it.

Thanks
Chris

 

Welcome dude and more importantly than heat get new boots on those joints! It could be your climate control module that is reading 73, 74 degrees, whatever but not actually requesting that to the heater core and fan blower give you that. That piece that the heated seat buttons are on all come out as one thing and is simultaneously replaced the same way. Also they are decently cheap.

 

it could also be a bad air blend flap

 

Is there any way to test the control module? How about the air flap? The only way is through a scanner isn't it?
