  1. First hand-tighten bolts (1) securing support (right-side) (2) to central tube (3). Then tighten screws to torque.
  2. ⚠ 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.]
  3. Switch on ignition.
  4. ⚠ 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. There must not be anyone in the vehicle while you are connecting the battery. — Connect battery earth wire with ignition switched on Electrical system27Battery; Disconnecting and connecting battery.
  5. If airbag warning lamp K75 indicates a fault following installation, you must interrogate, erase and then re-interrogate the fault memory .

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.
