Report: Rainwater May Accumulate in Plenum Tray Due to Clogged Drains
Audi S8 Problem
Average Mileage: 85,650 mi (76,300 mi - 95,000 mi)
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.

Flooding in interior cabin 2 different times due to clogs. Car is garaged at home and carport at work. Mechanic says leaf blowers are big culprit.
