MG 5 airbag control unit repair⁽¹⁾

What should be considered with MG 5 airbag control units?

The MG 5 airbag control unit evaluates the signals from the crash sensors, triggers the airbags and belt tensioners and reports faults via the airbag warning light. After an accident it stores crash data and locks itself, so the unit should be checked by a specialist workshop.

The control unit monitors the entire restraint system, including airbags, belt tensioners and crash sensors. A fault shows up as a lit airbag warning light in the instrument cluster. The system is safety-relevant, so you should not work on the airbag system yourself.

Airbag24 offers repair of the MG 5 airbag control unit by mail-in service. The control unit you send in is repaired, the crash data is erased and the unit is tested after the repair.

Which MG 5 generations are there?

The MG 5 is built in its 1st generation. This model series has been on the market since 2021 and is still in production.

For identification, the model name alone is not enough. The model year and the control unit itself also count.

• 1. Generation (since 2021) – current MG 5 series, still in production

How do I identify my MG 5 airbag control unit?

You recognise your MG 5 airbag control unit by the part number on its label. Together with the model year and the vehicle identification number (VIN), this number determines the exact version.

The part number is the most important reference point; model year and equipment should also be checked. The following part number is recorded for the 1st generation of the MG 5. The list does not claim to be complete:

• 11040809

Fault codes help with classification. These examples come from the recorded fault codes of this series:

• B1932: frontal trigger data recording stored, crash data in the control unit
• U0151: communication with the airbag control unit lost
• B0001: driver front airbag stage 1, firing circuit faulty

A single fault code does not prove a defect. The workshop determines the cause during testing.

What airbag equipment does the MG 5 have?

According to manufacturer information for the British market, the MG 5 comes with driver and front passenger airbags, front side airbags and curtain airbags as standard. Equipment may vary by market and trim level.

This information comes from manufacturer material and dealer specifications for the United Kingdom. The vehicle papers and the equipment list show whether a car from another country is equipped the same way.

Your route to repair: have the fault memory read at a specialist workshop. The workshop disconnects the battery and removes the control unit. Then create a repair order online with Airbag24 and send in the unit.

Processing usually takes 3–4 working days and covers testing, repairing and checking the unit. The repaired control unit returns with all vehicle data and is ready for use immediately after reinstallation — no coding or programming is needed.
