Cabin Ventilation Duct: Testing and Inspection

Air Extraction Vent, Checking







- Check air guides to both air extraction vents - A - for blockage (left and right).
- Sealing lips - B - in air extraction vent - A - must move freely and close automatically.
- Clogged air guides or gummed sealing lips could cause windows to mist up.

NOTE:
- The illustration shows the air extraction vent for a Saloon with the rear bumper removed. A different type of air extraction vent is installed on the Avant.
- One air extraction vent each is installed on left and right for forced air extraction.







- To ensure proper functioning of passenger compartment ventilation, the vent openings - C - in the luggage compartment lining are never to be sealed off.
