my check engine light started coming on last winter, i had it tested by a local garage(closest audi dealer is over an hour away) he said it came back as a faulty code and he couldnt really do much, long story short... after some research I decided that it had to be a bad ect sensor, called and had one delivered, it was the correct one, so i changed it, well 2 weeks later my check engine light is still on and my temp guage is still eratic, i heard somewhere that there are actually 2 ect's on the 12v but i hope that isnt true cuz the first one took me 2 days to find(no bentley manual) and almost 2 hours to change(very tight quarters). Any thoughts?

The code should tell you what the problem is. It could be your thermostat. It could be anything unless you find out what the code is.

a local garage ran it and i dont know the exact code, although he said it had something to do with the coolant temp. i decided to change the ect sensor after reading several posts about how common the ect senosr failure is and the symptoms that the car would have if it did fail-ie. eratic coolant temperature and check engine light on and off

There is a list of people that have VAG-COM that can help you out but I forgot where the list is, if you are in austin, tx, I can help u.

Your car apparently has more than 1 more trouble codes, IMO. That's the thing that you want to make sure.

Good luck.

I'm not sure but I think you also need to reset the MIL...
