ok so i know this was talked about before on a different thread but mine on my 99 a6 2.8Q is not the same as the ones people were talking about.. so i went to the dealer today to get the part and it looks like a little nipple about a inch long and gold in color and i thought, thats it? well apparently mine goes in the front somewhere according to there diagram but its to hard to access and needed to take off the radiator or seomthing..so i thought f- it its not that important.. but is it? i just replaced the colant temp sensor with ease and just wondering how hard it is for the oil temp.? is it worth the work and 30$ part?

thanks
