Instructions. The cabin filter is available in various designs (without or with activated carbon filter insert). On vehicles with climate control. performance installation "Komfort" Currently, a cabin filter with activated carbon is installed on vehicles with climate control, installation version "Basis" A cabin filter without activated carbon is currently being installed. Clean around the cabin filter in the air conditioning duct before installing a new filter. On vehicles equipped with driving training equipment, additional pedals must be removed if necessary (depending on the version for additional The pedals have places for service disconnection.
Move the passenger seat to the rearmost position. Remove the screw clamp -A- and the soundproofing mat -B-.
Cover the floor covering in the area under the cabin filter with paper.
Release clamps -B-, move cover -A- in direction of arrow -arrow- and remove cover.
The cover -A- can be secured with bolts -D- at the mounting points -C- if the latches -B- no longer hold it in place. Remove the cabin filter -A- from the air conditioning duct -B-.
Installation
Installation in reverse order: after removing the cabin filter -A-, clean the air conditioner through channel -B- (for example, a vacuum cleaner). Install the cabin filter -A- (straight, bevel -C- to supply fan side -D-). For the cabin filter -A-, intended for this vehicle, the flow direction is not defined. The cabin filter is available in various versions: without filter insert with activated carbon or with it, pay attention to the correct version (with and without activated carbon filter insert).
Possible causes of odors
The smell of burnt oil in most cases occurs in the engine. compartment due to a leak in the engine or gearbox. Sulfuric exhaust smell. Consequence of a leak in the exhaust system. Consequence of exhaust gas entering the cabin when reversing (when moving through an exhaust cloud). The coolant smells like fish. A consequence of a leak in the engine cooling system or air conditioner heat exchanger. If depending on the selected temperature (under regime "Cooling" weaker than under regime "Heating") a smell reminiscent of fish appears, check the air conditioner heat exchanger for leaks (the heat exchanger is sometimes purged with air).
Burnt clutch smell. Fumes from the foot mat, additionally installed seat covers, etc. Rotten and stale smell from the plenum box. A consequence of the accumulation and deposition of various contaminants, such as leaves, pine needles, etc. A consequence of stagnation of water in the drainage box. Check the drainage box drains.
Air conditioner smell. Odors arising in the climate of the installation are felt both in the supply ventilation mode and in the air recirculation mode. If the smell appears only in the supply air mode or only in the recirculation air mode, then in most cases the cause is not in the air conditioner. If the heat exchanger is leaking, the smell of escaping coolant often depends on the set temperature; when the temperature is set "Cold" the heat exchanger is not blown through with air and the smell is not so strong. A consequence of too much condensation in the air conditioner. Check both air conditioner condensate drains.
Consequence of unsuitability or severe contamination of the cabin filter. Check the cabin filter. A consequence of the formation of deposits on the evaporator plates. Clean the evaporator using the ultrasonic cleaner -VAS 6189-.
