The engine compartment of any motor vehicle is a hazardous area .
The engine compartment should be cleaned by a qualified workshop. Corrosion protection could be removed and electrical components damaged if the compartment is cleaned incorrectly. Furthermore, water could enter the vehicle interior directly via the plenum chamber .
If the engine compartment is very dirty, we recommend that you always go to a qualified workshop to have it cleaned by a professional mechanic. Volkswagen recommends using a Volkswagen dealership for this purpose.
Plenum chamber
The plenum chamber is located in the engine compartment between the windscreen and the engine and has a perforated cover. Air from outside is drawn in from the plenum chamber and is passed into the vehicle interior via the heating and fresh air system and the air conditioning system.
Leaves and other loose objects must be removed from the cover of the plenum chamber at regular intervals using a vacuum cleaner or by hand.
