Default Where the AIT sensor on the 2.7 engine?

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!

Default RE: Where the AIT sensor on the 2.7 engine?

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
