Various Probelms Caused by Clogged Plenum Tray Drain on Volkswagen Passat W8

Problem Description and Possible Solution

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.
