Re: 1996 audi not heating up
Hi Sounds like your thermostat needs replacing to cure the cold running.
As for the ticking sound, check your engine oil first, if its OK. its usually the hydraulic tappets, and a can of STP or Wyns oil addative in with the engine oil, can sometimes quieten them down !
Good Luck !

i would say it is the the thermostat. it makes the engine heat up to i am pretty sure 195 degrees at a fairly quick rate then opens to cool the engine once to running temperature and opens and closes as needed to keep temperature at the manufactures setting. some get stuck open so they never truly heat up.
Many things cause an engine to run hot: faulty engine thermostat, radiator or head gasket; a cooling system leak (low coolant level), inoperable cooling fan, etc. Don't throw parts at it. Have it checked out and repaired by a reputable shop in your area. The cost would be considerably more for an engine replacement.
REPLACE THERMOSTAT.MAKE SURE COOLANT SUPPLY PIPE OR COOLANT RETURN PIPE NOT STOPPED UP AND YOU HAVE ENOUGH COOLANT IN THE SYSTEM.REPLACE THERMOSTAT.CRANK ENGINE UP AND LET IDLE UNTIL WARM UP KEEP EYES ON TEMPERATURE GAUGE. WHEN ENGINE THERMOSTAT OPEN COOLANT HOSE SHOULD BE HOT.IF NOT TURN OFF ENGINE.USE LARGE RAG WAIT A WHILE BEFORE REMOVING RADIATOR CAP CHECK TO SEE IF COOLANT LEVEL DROPPING IF SO ADD MORE COOLANT.CRANK ENGINE UP UNTIL THERMOSTAT OPENS UP.HOSE WILL GET HOT.IF STILL COLD CHECK COOLANT LEVEL.ONCE YOU AIR OUT COOLANT SYSTEM RADIATOR HOSES WILL GET HOT SO YOU WILL GET HEAT.IF COOLANT LOW YOU WONT GET NO HEAT.
when you start the car and let it warm up, does it reach normal operating temp.? Does the needle stay in the middle? If not, it's time to replace the thermostat. If it's ok, then your blend door is stuck or broken and may need replacement or repair. when you move the control to hot or cold, the blend door opens accordingly allowing cold hor hot air in.
Sounds like your thermostat is sticking open, when this happens your coolant in your engine isn't given enough time to warm up and just cycles threw to your radiator, which cools the fluid not allowing it to get warm/hot. Thermostat tend to go bad, this is most likely your issue, just have your thermostat and gasket for your thermostat replaced too. Your looking at about 10 dollars in parts maybe 20 dollars in labor! If this helped give me a thumbs up please!
unless you got visable signs of leakage its not heater core, but it could be pluged with sediment. take off both heater hoses and flush it both ways until it runs clear. you can also mix a little baking soda and water and pour in core and let set for a while and then flush.
you can open the radiator cap before starting your engine and let it worms up and you can see by looking in to the rad if you have circulation maybe you will have to rev engine just a little if the new thermostat work it will circulate godd and check to make sure fan does come on new sensors but fan may be the problem be cautious as it gets hot . and also make sure there is no air in the system with the cap off and little rev if air is present it should come out good luck
