Car stays cold!

[fitch303]

Ok so yesterday I was driving to work and my windows were fogged so I turned on my air to clear it up. Thats when I noticed my temp gauge was still on cold after 20 mins of driving, and no hot air would come through the vents. So I got out and felt the engine and it was still cool to the touch which was weird. So I sat in my car and noticed the temp needle would go move between cold, and the first 1/4 mark. I changed my radiator 3 weeks ago and thought I bled it for air enough. Any ideas?

probably still have air in the lines somewhere....although your engine should get hotter if you have air as there would be no liquid cooling it down....maybe your thermostate got crap in it and is now stuck open.

do you hear the fans constantly on? mine is doing htat now. it's at the shop and they dont know what the issue is. they already replaced the ect which is the normal fix for these things but it did it again and so they replace another unit somehwer by the radiator and that worked for like a few days but then the fan is now on again at full on this time eveyrtime i start the car :(

well if I hold the rpm at 3k for a minute the temp goes up to normal, but when I turn on the heater or lay off the gas the temp goes back down. I didn't notice the fan working incorrectly, but I will check again.

I had the same problem last year. It ended up needing a new thermostat.

WTF, 60k miles on this thing problems already surfacing. Audi/vw = pos reliability.
