Abarth 124 Spider airbag control unit repair⁽¹⁾

What should I know about Abarth 124 Spider airbag control units?

The airbag control unit of the Abarth 124 Spider evaluates the crash sensors, triggers the airbags and belt tensioners, and monitors the entire airbag system. If it detects a fault, the airbag warning light on the dashboard comes on. Airbag24 repairs your own control unit that you send in.

After an accident, the control unit stores crash data and locks itself. A defective control unit can impair the function of the entire airbag system. The airbag system is safety-critical, so any work on it should be left to a specialist workshop.

The repair takes place in our workshop in Berlin. There we check the control unit, delete the stored crash data and repair the unit.

Which Abarth 124 Spider generations are there?

Our vehicle data lists the Abarth 124 Spider with series 348, built from 2017 to 2019. The series helps to classify the vehicle and its control unit.

The Abarth 124 Spider is a convertible roadster. The series designation 348 identifies the version recorded in our data. The construction period given is taken from our vehicle data.

• 348 (2017–2019) – series of the Abarth 124 Spider, to be checked together with the model year and part number when assigning the unit.

How do I identify my Abarth 124 Spider airbag control unit?

The part number on the label of the control unit determines the exact version. In addition, check the model year and equipment of your vehicle before you send the unit in.

The part number is on the label of the control unit and shows which version is fitted. Model year and equipment help with classification but do not replace the part number. Our product data lists the following part numbers for the Abarth 124 Spider. The list is not complete:

• N243-57K30
• NA1J-57K30

Our data lists Bosch as the supplier. As examples of fault messages we cite U0151 (communication with the airbag control unit lost) and B0001 (driver airbag: ignition circuit interrupted). A single fault code, however, does not prove a defect; only a diagnosis shows the cause.

What airbag equipment does the Abarth 124 Spider have?

The Abarth 124 Spider is fitted with front airbags for driver and front passenger, plus side airbags. Whether it also has head or curtain airbags is not clearly documented.

The driver airbag sits in the steering wheel, the front passenger airbag in the dashboard. The control unit coordinates all airbags in the vehicle; if the warning light shows a fault, the cause may lie in the control unit, but it does not have to. The exact equipment of your vehicle is listed in the vehicle documents and the owner's manual.

To have your control unit repaired, first have the fault memory read out. The battery is disconnected before removal, and a specialist workshop should carry out the removal. Then create a repair order online and send the unit to us by parcel. Processing usually takes 3–4 working days: we check, repair and test the unit. The repaired control unit comes back with all vehicle data and is ready for use immediately after reinstallation — no coding or programming is required.
