Mercedes Airbag ECU Continental / Siemens 5WK43871 | A2129010700 – Programming / Reset / Repair Service

Mercedes Continental Airbag ECU A2129010700 / 5WK43871 Crash data reset / Cloning service

This listing is NOT to supply an airbag ECU module - This is a crash data removal / ECU cloning service!

To use this service simply remove the airbag ECU from your vehicle (Usually located in the centre console), place your order & send us your module / modules & in just a few days it will be returned to you ready for refitting - no programming will be necessary after it is fitted & in most cases, there is no need to remove fault codes with a diagnostic scanner. It is essential that the deployed airbags / seat belt pre-tensioners have been replaced in the vehicle before refitting of your unit otherwise the warning light will remain illuminated. To check if we can reset / clone your module please search our database, if you cannot find it listed then contact us with your part number on your airbag module.

• The 'Crash data reset' service option above is required when a vehicle has been involved in a collision and your airbags or seat belt pre-tensioners have been deployed - In many cases this can be used to remove an 'Internal control module error' fault code. This is NOT a repair service for an airbag module that has hardware faults or has 'No communications' with the vehicle systems or diagnostic tools. Crash data on an airbag module is logged in the fault memory of the airbag ECU and will cause the 'Airbag warning light' to be illuminated, these faults cannot be removed using diagnostic tools. We can reset Airbag module Crash Data from almost all makes and models when usually the manufacturer or dealership would advise replacing the module with a new unit saving you large amounts of money!
• The 'Cloning service only' option above is if you have a faulty airbag ECU (Electronic Control Unit) on your vehicle, for example it may be water damaged or have a blown component quite often 'No communication' with the vehicles electronic system & diagnostic tools. If you are looking to replace the ECU you may be aware that in many cases you cannot simply remove an ECU from another vehicle & install it onto yours as the ECU is 'Coded' or 'Locked' to a different vehicles electronic / immobilizer system. We have the solution! Simply send us your original (Faulty) ECU & the donor (Replacement) unit & will will transfer the data from your original to the replacement enabling the used unit to work on your vehicle with no further programming necessary. Once the donor unit has been programmed (Cloned) your vehicle will then have the airbag system working correctly again, the coding of the unit will be correct & the airbag warning light will function as it should.

*Please note for cloning services please ensure your original & donor parts have matching part numbers! We will not be held responsible for compatibility issues if you supply incorrect parts*
