Fresh Air Intake Duct Temperature Sensor

On the Audi R8, the Fresh Air Intake Duct Temperature Sensor (G89) is installed in the air intake unit but is not included in the electrical evaluation.

Removing

- Switch off ignition.

- Remove the air intake unit, refer to => [ Air Intake Unit ] Air Intake Unit.

- Remove the air intake unit upper cover, refer to => [ Air Intake Unit Upper Cover ] Air Intake Unit Upper Cover.

- Disconnect the electrical connector - A - on the fresh air intake duct temperature sensor - B -.





- Turn the fresh air intake duct temperature sensor approximately 90° in the - direction of the arrow - and remove it from the intake shroud.

Installing

To installed, perform the steps done during removal in reverse order. Note the following:

- Install the temperature sensor - B -.

- Connect the connector - A - on the temperature sensor - B -.

- Before installing the air intake unit upper cover, make sure the connector - A - is seated correctly and the wiring harness is routed correctly.

- Install the air intake unit, refer to => [ Air Intake Unit ] Air Intake Unit.

After finishing the repairs, perform the following work on the Climatronic Control Module (J255) using Vehicle diagnosis, testing and information system VAS 5051/ in the "Guided Fault Finding" function:

- Check the DTC memory and erase any malfunctions shown.
