Plenum Chamber, Checking For Debris: Notes
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2015 Audi S7, 2015 Audi RS 7, 2015 Audi A7 Quattro, 2014 Audi S7, and 2014 Audi RS 7. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Deposits in the plenum chamber such as leaves or pine needles can collect in the water drains and prevent water from draining out of the plenum chamber. This can cause the water level in the plenum chamber to increase (for example, in car washes and heavy rain). The water enter the vehicle interior through the grommets or the fresh air intake housing.
-- Remove the plenum chamber cover. Refer to PLENUM CHAMBER COVER, REMOVING AND INSTALLING .
