If you park under a tree at home or at work, be sure to take heed of this tip. Volkswagen recommends that you remove leaves from the plenum panel (the plenum is the area in front of the windshield and under the hood). Keeping the plenum panel clean prevents the water drain underneath from becoming blocked. Clogged drain holes can lead to water and debris entering the vehicle interior through the heating and ventilation ducts.
If water and/or debris build up due to clogged drain holes, the result can be problems with your battery, your ventilation system, or other issues. A little bit of cleaning can keep your drains open and save you trouble down the road.
