Note
Failure of LEDs in additional brake lights:
The individual LEDs (light-emitting diodes) in the additional brake lights are comprised in groups of 4 LEDs and are supplied with current in groups.
The additional brake light is designed in such a way that the legal requirements are still met in the event that one LED group fails.
If a further LED group fails, these requirements are no longer met according to the legislator.
Due to the failure of one LED group, the intact LEDs are placed under increased strain; it must be anticipated that further LED groups will soon fail.
If more than 4 individual LEDs in the additional brake light have failed, the additional brake light must be renewed (repair measure).

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.
