Genuine used Volkswagen Transporter T5 Airbag Control Module / SRS ECU, part number 1C0909605A. This module is used to monitor and control the vehicle’s airbag restraint system and is documented for Transporter T5 applications from the early T5 production period.
Part Number: 1C0909605A
VW OE Number: 1C0 909 605 A
Manufacturer Reference: Siemens 5WK43122 is commonly associated with this module.
Part Type: Airbag Control Module / SRS ECU
System: Supplemental Restraint System
Application: Airbags / Crash Detection / Safety Restraint System
Compatibility:
Suitable for selected:
* Volkswagen Transporter T5 – approx. 2003–2010
* Transporter Panel Van / Kombi
* Caravelle / Multivan applications where the same module and airbag configuration are fitted
The same 1C0909605A number is also documented across several other Volkswagen Group vehicles, so the part number alone does not mean every module is interchangeable between all models.
Technical Information:
The airbag control module is the central electronic control unit for the vehicle’s Supplemental Restraint System.
Depending on the vehicle specification, it can monitor and control:
* Driver airbag
* Passenger airbag
* Side airbags
* Curtain / head airbags where fitted
* Crash sensor signals
* Airbag warning lamp
* SRS system diagnostics
The module continuously checks the restraint system for electrical faults. In the event of a qualifying collision, it processes crash information and determines whether the relevant restraint components should be activated.
Common Symptoms of a Faulty Airbag Module:
* Airbag / SRS warning light remains illuminated
* Diagnostic communication fault
* Internal control module fault codes
* Airbag system disabled
* Module damaged following a collision
* Crash data stored in the ECU
* Water or corrosion damage
* Electrical supply or CAN communication faults
Useful Diagnostic Information:
An illuminated airbag warning light does not automatically mean the control module itself is faulty.
Before replacement, it is advisable to check:
* Airbag connectors
* Under-seat wiring
* Seat belt pretensioners
* Driver and passenger airbags
* Side-airbag circuits
* Relevant fuses
* Power and ground supply
* SRS diagnostic fault codes
A proper diagnostic scan should be carried out before replacing safety-restraint components.
Programming / Coding:
A replacement airbag module may require coding or configuration to the vehicle depending on the module version and original equipment.
Used modules can also contain stored crash data from a previous vehicle. Specialist SRS services specifically offer reset services for 1C0909605A, so this should be checked before installation.
Important Compatibility Note:
Please compare all of the following with your original module before ordering:
* Full part number 1C0909605A
* Suffix letter A
* Siemens / manufacturer reference
* Software / index number
* Electrical connectors
* Number of airbags fitted to the vehicle
* Side / curtain airbag specification
* Vehicle model year
The suffix and index are particularly important, because different 1C0909605 variants can correspond to different airbag configurations.
Condition:
Used genuine Volkswagen electronic module. Normal cosmetic marks and signs of previous installation may be present. Please inspect the listing photos carefully for the exact part number, index, connectors and casing condition.
Ideal replacement for a faulty, damaged or non-communicating original Volkswagen Transporter T5 airbag control module, subject to correct diagnosis, matching and coding/reset requirements.
