🧭 Before you start
Fits: platform code FV
Don't miss
- Make sure electrical connectors are fitted correctly (as far as stop) and engage audibly.Make sure that wiring is not trapped.
- If the airbag warning lamp K75 indicates a fault following installation, you must interrogate, erase and then re-interrogate the event memory .
📋 Procedure
- ⚠ Observe safety precautions when working on pyrotechnic components .Before handling pyrotechnic components (e.g. unplugging the electrical connector) the mechanic must discharge any static electricity. This can be done by briefly touching the door striker plate, or similar. — Move front seats as far forwards as possible and tilt backrests as far forwards as possible.
- With ignition switched on, disconnect battery earth wire Electrical system27Battery; Disconnecting and connecting battery.
- TT Roadster: Unclip back panel trim (centre) (1) with wedge T10383/1(arrow) and detach.
- TT Coupé: Remove centre console .
- Remove bolt (1) and detach crash sensor (2) for side airbag from body.
- ⚠ Before handling pyrotechnic components (e.g. unplugging the electrical connector) the mechanic must discharge any static electricity. This can be done by briefly touching the door striker plate, or similar. — Unplug electrical connector (3).
- To do so, pull out and press down connector locking element (2)(arrow) and unplug electrical connector (1) at crash sensor.
- ⚠ Observe safety precautions when working on 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. — Attach connector (1) to crash sensor (arrow) so that it engages audibly.
- Press in connector locking element (2) to secure connector. [Note: Make sure electrical connectors are fitted correctly (as far as stop) and engage audibly.Make sure that wiring is not trapped.]
- ⚠ 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. — With ignition switched on, connect battery earth wire Electrical system27Battery; Disconnecting and connecting battery. [Note: If the airbag warning lamp K75 indicates a fault following installation, you must interrogate, erase and then re-interrogate the event 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.
