So as winter is coming I started trying to use the heater in my 2002 A4. However it simply decided that it didn't want to throw hot air! The fan works fine because the volume of air it does throw out is plenty, but it just not HOT even on high. Id say its no warmer than 10 degrees Celsius air coming out! The ac works fine though, cold cold air comes out when that is on. Anyone know what's wrong and/or how to fix it? I was thinking its probably the heater core. Anyone else have any issues like this?

Re: B6 A4 heater not working
Is the car heating up? Does your temperature gauge reach the 90C mark?

Re: B6 A4 heater not working
As above, if the temp comes up normally your thermostat is probably OK. Most fail in the open position. You could try flushing your system to make sure that coolant is circulating properly in order for your heater to get up to temperature.Comment

Re: B6 A4 heater not working
This is what is happenning, and have seen this many times over with the Audi's. For some reason the heater core gets clogged up and reduces the amount of coolant getting through it if any. What you need to do is pull off the two heater core hoses and stick a garden hose in one end of the heater core spout. You will need the garden hose trigger handle that is found in almost every household. its the pressure that you want from the gerden hose. Just flush it right out until you see clear water coming out the other spout of the heater core. You will have to bleed all of the air out of the cooling system after you reconnect the two hoses back onto the heater core.Originally posted by ColinAndrews View PostLast edited by vee_dubbin; 10-27-2010, 05:49 PM.TWO TON ENGINE LIFT/CRANE FOR RENT

Re: B6 A4 heater not working
Tunedub did a $150 fix on our b5 passat cause it wasnt blowing heat at a stop and it was pitiful while moving.
George kind of explained it, but i dont remember, but i know it works!Comment

Those are the symptoms of a clogged heater core.Originally posted by Eurotuner. View PostTWO TON ENGINE LIFT/CRANE FOR RENT

Re: B6 A4 heater not working
We tried flushing it with the hose and it flowed perfectly and no crap came out of it.Originally posted by vee_dubbin View PostComment

Re: B6 A4 heater not working
No problem Scott. I'm glad we could sort it before it got cold enough to really need your heat.Comment
