I have a 1996 Audi a4 Quattro and the heater core went on it and I changed it out and I believe that I got it all bled out but after driving it for 20 mins the oil temp is up around 275 and the coolant reservoir will be full. The heat/ac control center when you turn the car on reads 71 degrees but as soon as the blower fan comes on it reads 7.1 degrees and no heat blows out. Took a temp gun and shot the radiator hose entering the radiator was 194 and exiting the radiator was 74. Need help please

SOURCE: 2001 Audi A4 2.8 no or little heat

there is a valvve that lets the coolant thru the heater core when heat is selcted then when it is off it goes thru thur the return instead of the heater core i bet your car is running a little off if it is the vavle works of a vacuum line and the vavle has a crack in it

have the oil pressure checked as soon as you can... also have them check the wiring for the oil sending unit

Please rate this solution thanks

SOURCE: 96 audi a4 heater blows cold air

you have air in the system!! you have to unbolt the filler tank and lift it 5 inch higer first. then loose the right hose on the heater core( this hose have and hole to bleed the system) and then put antifreeze until the antifreeze will go out of the hole then re install the hose to the heater core, then ajust the level correcty
have fun

SOURCE: coolant in coolant reservoir did not fill low level in radiator

you must drain air out of system
so when engine is warmed up, just unscrew slightly the thermo time switch which is the highest sensor and unit in cooling system besides the reservoir, until alittle air releases then when antifreeze starts coming out then retighten to specs. BE VERY CAREFUL !!!! LOOSEN VERY SLOWLY AND NOT COMPLETELY REMOVE FOR THIS CAN CAUSE BURNS. MIGHT WANT TO USE A RAG AROUND SENSOR. If this doesnt solve it then make sure you have the correct rad. cap. Also that the filling hose is not clogged as well as the little port on radiator.

Could be thermostat this regulates the water flow around the engine to keep it cool sounds like it is sticking open when water gets hot!!
