Mercedes-Benz CLK Airbag Control Module Replacement Parts

This is a boundary question worth treating carefully: the CLK W208 ran from 1997 to 2002, and the W209 generation replaced it from 2002 onwards, so a 2003 and a 2006 CLK are both W209 but you should confirm with the breaker that the module from the donor car matches your exact SRS system configuration before buying, as pretensioner variants can differ within a generation. The W209 generation ran through to 2009 with a facelift around 2005, and while modules from the same generation are more likely to be compatible, this cannot be guaranteed without checking your registration details against the donor part. Always have an airbag control module fitted by a qualified professional, as it is a safety-critical component.

Yes, generation is the most important factor — the first-generation CLK (W208, 1997–2002) and the second-generation CLK (W209, 2002–2009) use different SRS systems and the modules are not interchangeable between them. Within the same generation there is also a facelift to consider (the W209 was facelifted around 2005), so confirm with the breaker whether the donor module matches your specific SRS setup by providing your registration. Never attempt to fit a used airbag module yourself — this is a safety-critical part requiring professional installation.

The core airbag control module function is generally consistent across CLK trim levels such as Elegance, Avantgarde, and AMG Sport within the same generation, so trim level is not typically the primary fitment concern here. However, seat style and occupancy sensor configurations can vary between trims, which may affect SRS system behaviour, so you should confirm with the breaker that the donor module is compatible with your specific trim and seat setup using your registration. As with all airbag-related parts, professional fitting is essential.

Airbag control modules are single-use components — once the airbags in a vehicle have deployed, the module records the crash event and cannot simply be reset for reuse in most cases, so you will need a replacement unit from a non-deployed donor vehicle. A used module from a breaker is a legitimate route, but you must ensure it has not been previously triggered and that it is compatible with your exact SRS system, which is best confirmed with the breaker against your registration. Because this is a safety-critical system, fitting must be carried out by a qualified professional who can also ensure the module is correctly coded to your vehicle.

No — engine choice does not affect airbag control module fitment on the CLK, so whether you have a 1.8, 2.0, 3.2 or any other variant makes no difference to the module you need. What matters is the generation (W208 or W209), the model year, and potentially your trim level's seat and sensor configuration. Provide your registration to the breaker so they can confirm the donor module suits your specific SRS system before you commit to buying.

No — the W208 (1997–2002) and W209 (2002–2009) are entirely separate generations with different electrical architectures and SRS systems, so their airbag control modules are not interchangeable. Always source a module from the correct generation, and give the breaker your registration to verify compatibility with your specific SRS configuration, as variants can exist even within a generation. Airbag control modules are safety-critical parts and must be fitted by a qualified professional.
