Don't miss
- Arrow points in direction of travel.
- Make sure electrical connectors are fitted correctly (as far as stop) and engage audibly.Make sure that wiring is not trapped.
- If airbag warning lamp K75 indicates a fault following installation, you must interrogate, erase and then re-interrogate the fault memory .
📋 Procedure
- ⚠ Observe safety regulations for pyrotechnic components . — Remove glove box .
- Unscrew bolts (2) securing left-side support (1) to central tube (3).
- Detach support (left-side). [Note: Arrow points in direction of travel.]
- Unscrew bolts (1) securing support (right-side) (2) to central tube (3).
- Detach support (right-side). [Note: Arrow points in direction of travel.]
- First hand-tighten bolts (1) securing support (right-side) (2) to central tube (3). Then tighten screws to torque.
- ⚠ Observe safety regulations for pyrotechnic components .Before handling pyrotechnic components (e.g. plugging in the electrical connector) the mechanic must discharge any static electricity. This can be done by briefly touching the door striker plate, or similar. — Install glove box . [Note: Make sure electrical connectors are fitted correctly (as far as stop) and engage audibly.Make sure that wiring is not trapped.]
- Switch on ignition.
- ⚠ The battery must be connected with the ignition switched on. If pyrotechnic components (e.g. airbag or belt tensioner) are inexpertly repaired, this may result in unwanted triggering after connecting the battery.

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.
