Water Drain, Cleaning
WARNING: This page does not describe the selected car, but rather 18 other vehicles, including the 2016 Audi S4, 2016 Audi A4 Quattro, 2016 Audi A4, 2015 Audi S4, and 2015 Audi A4 Quattro. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Leaves, tree needles, etc. inside the plenum chamber can block the water drain. This causes the water to collect (for example in a car wash or heavy rain) and the water then can get into the inside of the vehicle through the grommets or through the fresh air intake housing.
NOTE:
Cleaning is a separate charge.
-- Remove any heavy debris inside the plenum chamber and in the water drain grommets with a flexible grip tool.
-- Remove fine deposits using a thin water hose or a suction feed spray-gun VAG 1538 and a flexible nylon tube VAG 1538/2.
-- Install the plenum chamber cover. .
