Fitting location of remote control receiver for auxiliary/supplementary heater
Note
A remote control for the auxiliary heater is currently only available for vehicles without high-voltage system, and not for vehicles with high-voltage system (Audi A3 e-tron). As an optional extra on vehicles with high-voltage system, the auxiliary heater / auxiliary ventilation can be switched on and off using

(via a mobile phone and
control unit 1 for information electronics

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.
