I knew where it was on my A4 but now I am getting a fault code for my air intake temp sensor reading being too high on my A6. I wanna try cleaning it or possibly getting a new one. Where is it and where could i get a replacement one? (And please don't say dealer, cuz i refuse to deal with the local one here, they are retards... lol)

Looks like it is down under the f-hose on the front side of the engine (the leg that goes to the PCV system). The Bentley says you need to take off the intake manifold to replace it. The connector is item 13 in this picture.

Looked a little more on AudiWorld - I think the sensor is actually installed into the bottom side of the intake manifold - I'm pretty sure it's the sensor in the upper RH corner of this picture. This was fromone of the tech articles on changing the aux coolant pump. I think the same sensor is mounted on top of the intake for the 2.8 engine. Another bonus for the 2.7T owner!

the AIT is directly underneath the intake manifold. it is actully in the inake mani itself. it is a huge pita to get to. I cleaned mine by removing the TBB (disconecting the batt) opening the trotthe body and spraying break cleaner on the sensor it self. if you open the throttle you can barely see it.

if you decide to take off the intake manifold I would just suggest replacing the sensor with a new one.

contact vastperformance they usully will beat the dealer on priceing ad help you with any questions you might afterwards . not only that but I have found that it helps to have a good relationship with a experenced tuner/aftermarket company so you can have someone to turn to in a case like this

 

Hey thanks guys, I appreciate it!

 

Great Info thanks!

I was about to give up on researching the location.

Here is one for you guys, if I look into the throttle body with a flashlight by turning the butterfly plate, I see the IAT sensor surounded and almost submerged by dark colored water, or liquid. I have recently been having throttle response issues, and turbo lag could this be the source of the problem?

 

That would most definitely be oil in your throttle body...How many miles do you have on your car? How long did you experience this sluggishness?

I'm not very familiar with the turbo models, but as far as the butterfly plate I'm pretty sure it would open a little harder fighting the viscosity of the oil - you said is submerged, right?
Do you ever need to add oil over time in between oil changes?

You may have a PCV valve problem or (hopefully not) some of your piston rings may be worn out and allow oil to get into the manifold.
Any way you look at it, oil in the throttle body isn't a good sign.

 

Need a oil catch can.

 

I swear to god I wanted to mention that, but I thought he has no idea what I am talking about!!!

 

The sluggishness has been going on and off now for the past three months now. Also I've never had to add oil in between oil changes.

Is the oil catch can a hard DIY job on the A6? I was lookin at the S4 procedures and they looked a little complicated. Is there somewhere you can go to have one profesionally installed?
