ℹ️ Always cross-check the exact figure against your vehicle's factory manual before final tightening — a wrong torque can damage the engine. These values are extracted from workshop data and may not cover every variant or revision.
📋 Procedure
- Remove heater and air conditioning unit .
- Remove coolant pipes from heat exchanger .
- Unplug electrical connector at fresh air and air recirculation flap control motor and move wiring harness clear.
- Remove bolts (2).
- Release retaining tabs (1 and 3).
- Swivel air distribution housing (4) to rear (arrow), disengage and detach from evaporator housing (5). [Note: Even minute leakage at the tongue-and-groove joint between the air distribution housing and the evaporator housing can lead to whistling noise as a result of escaping air. For this reason, lubricate the connection points lightly with silicone grease or similar to completely seal the connection points. For silicone grease, refer to Electronic parts catalogue]

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.
