Video tutorial category A:

Vehicles with pollen filter after the blower motor

 

Step-by-step instructions

  • Place the drip tray under the condensation drain (➜ Fig. 1).
  • Line the footwell in the passenger area with floor protection (➜ Fig. 2).
  • Remove the cabin air filter and remove coarse dirt, e.g. leaves, from the ventilation system (➜ Fig. 3).
  • Guide the probe through the air duct to the evaporator (➜ Fig. 4) - if necessary, adjust the probe by carefully bending it.
  • Fill the complete 994 contents into the pressure cup gun and connect on the air side.
  • Place thumb on the guide disk (fixing the spraying direction (➜ Fig. 5) and perform spray test (➜ Fig. 6). CAUTION: Ensure the correct spraying direction and check whether the liquid drains off via the drain into the collecting tray.
  • Actuate the gun and flush the evaporator with the complete contents of the pressure cup gun by moving the probe back and forth (➜ Fig. 7).
  • Spray out the pollen filter box completely with 996 (➜ Fig. 8).
  • Wipe the pollen filter box completely dry with the microfiber cleaning cloth (➜ Fig. 9).
  • Insert the new cabin air filter (not included in the set) (➜ Fig. 12).

Important notes

  • ATTENTION: When cleaning high-voltage vehicles (BEV and hybrid), the following points must be observed: Work on high-voltage vehicles may only be carried out by authorized and instructed employees with proof of expertise (observe national regulations). Before starting work, high-voltage vehicles must be disconnected from the power supply by authorized personnel in accordance with the manufacturer's specifications. If this is not done, there is a risk of serious damage to health and damage to the vehicle. Before starting work, high-voltage vehicles must be de-energized by authorized personnel in accordance with the manufacturer's specifications. Failure to do so may result in serious health hazards and damage to the vehicle!
  • WARNING! Protect electronic components located in the cleaning area reliably against moisture!
  • CAUTION! Avoid contact of the evaporator fins with the metal probe.
  • If necessary, the metal probe can be adjusted by carefully bending it.
  • Cleaning with airco well® does not require any rinsing, e.g. with water!
  • Lubricate the thread of the pressure cup and the air control piston behind the actuating lever with silicone grease (e.g. TUNAP Human Technologie 907 or MP 107) after each cleaning.
  • It is recommended to wear protective equipment (PPE) such as goggles, mask and gloves during use.
