heater problem on 2002 Audi A4 Quattro

my audi a4 temp gauge is getting to normal range but the heater never gets hot no matter what the temp is set at in the car i know it could only be a few things but was hoping to narrow it down.

is the coolant low? do the hoses to the heater core get hot? if not, could be a flow problem. ever put stop leak crap in, could be plugged. have coolant work done recently, could be air bound. the temp flap motor should be checked using a diagnostic tester to make sure the flaps go to the "hot" setting.
