Report: Rainwater May Accumulate in Plenum Tray Due to Clogged Drains
Audi A6 Quattro Problem
Clogged drains can allow rainwater to accumulate in the plenum tray (at the base of the windshield). The water may leak into the vehicle's interior, brake booster, or electrical components, which can lead to major problems. Our technicians recommend keeping the tray clear of leaves, pine needles, and other debris.
