Fiat Ducato B0100-49 Repair – Peugeot Boxer & Citroen Relay:
Our B0100-49 repair service addresses internal Airbag Module faults that cause the airbag warning light to be illuminated. The B0100-49 fault code cannot be resolved by simply clearing or resetting the stored fault code. It is vital to repair this fault once apparent in your vehicle to ensure the correct operation of the airbag system. It should also be noted that a constant airbag light will be an MOT failure.
Whether your vehicle is a working van or a motorhome, we assess the original module and repair the internal fault and return it to you. We usually repair and dispatch your original module within 1–2 working days of receiving it.
When we return your repaired Airbag Module to you we will also include a full diagnostic report along with a VAT invoice for your records.

Frequently Asked Questions (FAQ):
What does a B0100-49 fault code mean on Fiat Ducato?
B0100-49 is commonly reported as an internal ECU fault. This fault is usually associated with a low or flat battery condition or caused by fluctuating battery voltage. A B0100-49 error may also be caused by corrosion resulting from moisture or condensation in or around the airbag module. This fault can prevent your airbag system from functioning correctly if you were to have an accident and as such should be repaired as a priority.
Do you offer Fiat Airbag Module B0100-49 repair?
Yes. Our Fiat Airbag Module B0100-49 repair service covers compatible Fiat Ducato, Peugeot Boxer & Citroen Relay Airbag Modules, including those fitted to Fiat Ducato-based vans and motorhomes.
Is B0100-49 caused by low battery voltage?
Battery voltage problems can present as either a flat battery or a fluctuation in battery voltage. These conditions are often associated with a B0100-49 fault. The issue typically occurs after the vehicle has been sitting idle for extended periods (such as over the winter). When you attempt to crank the engine with a weak or partially discharged starter battery, the massive electrical draw can cause the voltage to drop sharply which can also cause the failure and resulting B0100-49 fault code to be stored in your Airbag Module.
Will repairing the module resolve my airbag warning light fault?
Yes, usually all that is required is our quick and simple workshop repair. Your B0100-49 failure is very common and easily addressed by our technicians.
Is this the same as an airbag crash data reset?
An internal fault repair and a crash data reset address different issues with your airbag module. We will also reset and remove any stored crash data when we carry out the B0100-49 repair.
Will my module need coding after repair?
We repair and return your original module so no coding or Proxi Alignment is required.
How long will the repair take?
We will usually have your module in our workshop for 1-2 working days and then return to you by the method you select at checkout. The options are Tracked 24 or Royal Mail Special Delivery.
What warranty do you provide on a B0100-49 repair?
We give all of our B0100-49 repairs a 12-month warranty.
