Peugeot 306 Cabriolet airbag control unit repair⁽¹⁾

What should be considered for Peugeot 306 Cabriolet airbag control units?

The airbag control unit in the Peugeot 306 Cabriolet evaluates the crash sensors, triggers the airbags and belt tensioners, and monitors the entire restraint system. If it detects a fault, the airbag warning light on the dashboard comes on. Airbag24 repairs the customer's own control unit that is sent in.

After an accident, the control unit stores crash data and locks itself. A fault in the control unit can also keep the airbag warning light permanently on, even without an accident. As the airbag system is safety-critical, work on it belongs in the hands of a specialist workshop.

Whether a repair is possible in an individual case is shown by the check in our workshop in Berlin. There, the crash data is erased, the unit is checked for faults and tested after the repair.

Which Peugeot 306 Cabriolet generations are there?

The Peugeot 306 Cabriolet was built in two generations: I from 1994 to 1997 and I Facelift from 1997 to 2002. The construction year and the vehicle identification number (VIN) show which generation your vehicle belongs to.

The Cabriolet came onto the market in 1994 and is a convertible version of the Peugeot 306 range. The 1997 model update brought the facelift, which was built until 2002.

When matching the unit, the construction year and the part number are the key points. Check both before you send the unit in.

• I (1994–1997): first production phase of the Cabriolet
• I Facelift (1997–2002): revised production phase with model update

How do I recognise my Peugeot 306 Cabriolet airbag control unit?

The part number on the label of the control unit determines the exact version. Together with the construction year and equipment of your vehicle, the matching unit can be narrowed down.

The part number is printed on the label of the removed control unit. The list below does not claim to be complete, so always compare the number with the one on the unit itself.

Known part numbers include:

• 9620732580
• 9621996780
• 9636995580

Examples of fault codes are B1000, B1020 and B1040. The code B1020 stands for an internal fault in the airbag control unit. A single fault code does not prove a defect on its own; it must be checked on the vehicle.

What airbag equipment does the Peugeot 306 Cabriolet have?

According to specialist reports, the driver airbag was standard equipment from December 1994. Passenger airbags and side airbags were not standard in all production years.

According to the same reports, front and side airbags became standard equipment from May 1998. In the early production years, a passenger airbag was not standard on every vehicle, so the equipment of the vehicle in question is decisive.

Information on head or knee airbags cannot be clearly confirmed for this model; the equipment of your vehicle is decisive.

To have an airbag control unit repaired, follow these steps: have the fault memory read out, disconnect the battery and remove the control unit. As the airbag system is safety-critical, the removal must be done with great care; if in doubt, a specialist workshop should take it on. Then create a repair order online and send the unit in.

Processing usually takes 3–4 working days and covers checking, repairing and testing the unit. The repair takes place in our workshop in Berlin. The repaired control unit comes back with all vehicle data and is immediately ready for use after reinstallation — coding or programming is not necessary.
