1996 2.8 quattro

So my temp sensor is out or range, so that probably means its fried. This might explain my temperature gauge never getting to the middle. I was told to buy this sensor(pics below) and replace it. So I have a question where is it located? and what is a good plan of attack for changing this guy out as well? anyone do this? Thanks!

 

I have been wondering the same thing. I think you need to unscrew the plastics in the center of the engine under the hood and find it under all that. its def not visible. I need a new 1 too, my audis a 97 a4 quattro 2.8...whered u buy the sensor n how much?

ecs tuning has these and should be the green one. Our 2.8s are a little pta.
Also a common problem on our cars.
