First read and observe the introductory
information and safety warnings
The engine compartment of any motor
vehicle is a hazardous area
.
The engine compartment should be cleaned by a qualified workshop. An incorrect cleaning procedure could possibly remove corrosion protection and could damage electrical components. 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 following correct procedures. 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 or via the air conditioning system.
Leaves and other loose items must be removed from the cover of the plenum chamber at regular intervals using a vacuum cleaner or by hand.
