- Dust and pollen filter for contamination
- Forced ventilation vents for passenger compartment
- Ingress of water into passenger compartment
- Fresh-air intake from plenum chamber and plenum chamber water drain
- Seals between individual components of fresh air intake and vehicle for damage and leaks
- Activation of air conditioner compressor regulating valve N280 and operation of air conditioner Checking cooling output [Note: Under certain operating conditions, residual moisture in the refrigerant circuit may lead to the formation of ice at N280 (and at the expansion valve). Such ice formation impedes the control of the air conditioner compressor. The evaporator is cooled down too much and ices up. Icing-up of the evaporator may be the cause of the windows misting up.]

Who makes these pages, and how
TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.
The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.
Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
