Indication of achieved clamping force and dynamic deceleration
The lamp lights up with parking brake applied and ignition switched on.
The lamp stays on for approx. 30 seconds after the ignition is switched off.
If the parking brake is applied with ignition switched off, the lamp lights up for approx. 30 seconds.
The lamp should go out when the parking brake is released.

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.
