I have been told by the dealership it would cost over $200 just to put a part in that cost me only $10. Does anyone know if it is simple enough for me to put it in? I have the part plus o-ring. I popped the hood open and could not find it. I just don't want to pay some one that amount of money for them to spend no more than 10 minutes putting it in. Is it something I can get to easily without taking apart the whole car? HELP, PLEASE! Also Audi said they would have to put it back on the computer to have the "check engine" light reset, is that also true. Any tips will be greatly appreciated! Also I checked out the Chilton's Repair Book, that was NO help. The person who posted the other response for the engine coolant system was great except, it's not for my car.

Email someone nearby. Or, you can just wait a few days and it'll probably clear itself after a few startup cycles. Most stealerships will charge $75 just for computer diagnostics, so if they won't clear it for free, just leave it or find someone with the VAG-COM

My buddy has an '01 Passat and just had his coolant sensor replaced, the dumbass paid $100 to have it done. No check engine light, just erratic readings.

It's a pain in the ***.

The ECT Sensor is under the air tube at the rear passenger side of the engine.

and, yes it can cause a CEL.<ul><li><a href="https://forums.audiworld.com/a4/msgs/1921565.phtml">More info</a></li></ul>

I figured it was a pain in the *** but I wanted to be cheap about it. I know there is an article out there, printed it out, compared it to mine.... thats how I how that the one in the tech section IS helpful for those who have that type of A4. I think the one in the pics is an 1.8 or a different year. I'm working with a 2000 2.8 quattro. I replaced the spark plugs, no prob. (Yes I actually did, okay so I supervised). I just need this freakin sensor to make my baby run like the time I bought it.

Wait... why do you laugh?

Don't do it!!

The 1.8 seems easy, but the 2.8 is a real PITA. I have a 98 A4 2.8Q and I spent all day this past Saturday and messed up my car. I succeeded in removing and replacing the ECT but wasn't able to properly secure it and leaked coolant as a result. I can't imagine how you could secure the ECT again without having hands of a surgeon or taking apart some other parts in the engine.

Needless to say, I bloodied up my hand, lost the use of my car this weekend, leaked coolant all over the place, and was frustrated by it all.

I finally went to a local mechanic today and he took care of it in about 30-45 minutes. Parts = $30, labor = $75, total ~$100. Should have done this from the beginning instead of spending over 5 hours on the car, bloodying up my hands, and having to take public transportation to get around this weekend.

Find a local mechanic and spend the money... you'll be much happier.
