About this repair

Specialist Fiat Punto Airbag ECU Repair

Fiat Punto airbag ECU repair from Blackstone covers the black plastic Continental airbag control module used in compatible Fiat Punto models. An internal failure can cause complete loss of diagnostic communication, a permanent airbag warning light, flashing mileage and secondary dashboard messages such as “Fuel Cut-Off Not Available”. Other vehicle systems may store U172687 / U1726, 0042281, B10AA4A or B105386 because they can no longer communicate correctly with the airbag ECU.

First, we inspect the ECU and confirm the covered internal fault. Next, we repair it at component level and fully test communication and operation. We then return the same module, so its original vehicle data is retained. After refitting, a Proxi alignment may be required. Suitable diagnostic equipment will confirm whether this vehicle-side procedure is needed.

Before booking

Common Symptoms Associated with This Fault

  • SRS airbag warning light permanently illuminated
  • Airbag fault message displayed in the instrument cluster
  • Mileage display flashing in the instrument cluster
  • “Fuel Cut-Off Not Available” warning displayed
  • No diagnostic communication with the airbag ECU
  • Fault code U172687 / U1726, 0042281, B10AA4A or B105386 stored in another vehicle system
Important: Because the failed airbag ECU may be completely unresponsive, these communication codes are usually stored in other control modules rather than inside the airbag ECU itself. Confirm the unit type, power supply, wiring and connector condition before sending the ECU.
Compatibility check

Is This Repair Right for Your Vehicle?

Choose this Fiat Punto airbag ECU repair when the vehicle has the black plastic Continental airbag control module and the covered internal no-communication fault. This listing is for the later Fiat Punto type 199 with the compatible Continental module; it does not cover the earlier Punto type 188. Before booking, check each point below:

  • Confirm that the vehicle is a Fiat Punto fitted with the matching black plastic Continental airbag ECU.
  • Confirm loss of communication with the airbag ECU and/or one of the listed communication or configuration fault codes.
  • Check the ECU power supply, grounds, wiring, connectors and relevant vehicle-side network faults.
  • Remove the airbag ECU from the vehicle and send the module only.

Need help? Send us the complete part number, a clear photograph of the unit and any stored fault codes through our contact page or by email. We will then help confirm suitability before you order.

Simple process. Fast turnaround. Fully tracked.

How to Get Your Unit Repaired

Book online

Select Book Repair and complete checkout securely on our website.

Pack and send your unit

Remove the airbag ECU from the vehicle, protect the electrical connector and casing, then package the module securely using suitable protective material and the prepaid Royal Mail label. Please send the airbag ECU only and do not include brackets, bolts or other vehicle parts.

We repair and fully test it

Once received, the ECU is inspected, the covered internal no-communication fault is repaired, and communication and module operation are tested using dedicated bench equipment. Repair, testing and dispatch are completed within 48 hours of receipt at our workshop, excluding weekends and bank holidays — normally sooner.

We return it fast

Your original airbag ECU is carefully packed and returned by Royal Mail Tracked 24. Because the same module is repaired, its original vehicle data is retained. After refitting, a Proxi alignment may be required using suitable diagnostic equipment. This procedure is carried out on the vehicle and is not included as part of the postal repair service.
Please use the label we provide so your parcel remains fully tracked and qualifies for free postage.

Useful information

Frequently Asked Questions

What does the Fiat Punto airbag ECU repair cover?
This repair fixes the covered internal failure in the customer’s original Continental airbag ECU. It restores diagnostic communication and module operation. Unrelated wiring, supply, network, sensor or vehicle-side faults require a separate diagnosis.
My diagnostic tool cannot see the airbag ECU — can you still repair it?
Yes. Complete loss of diagnostic communication is the primary symptom this service is designed to resolve, provided the vehicle-side power supply, grounds, wiring and connectors have been checked.
Which fault codes are associated with this repair?
Common associated codes include U172687 / U1726, 0042281, B10AA4A and B105386. Because the airbag ECU may be unresponsive, these codes are normally stored in other vehicle control modules.
Will a Proxi alignment be required after repair?
A Proxi alignment may be required after refitting. Suitable diagnostic equipment will confirm whether it is needed. This is a vehicle-side procedure and is not included in the postal repair service.
How long does the repair take?
We start the 48-hour workshop turnaround when the airbag ECU reaches our workshop. The timeframe excludes weekends and bank holidays. In many cases, we finish sooner.
What happens if the unit cannot be repaired?
If we cannot repair the unit, we contact you and arrange a full refund under our No Repair, No Fee commitment. Every completed repair includes a 2-year warranty, subject to our warranty terms.
