GLC SRS Light On Airbag System Failure

My 2023 Mercedes GLC with a gasoline engine is showing an SRS light on the dash. The airbag warning lamp is constantly lit in the speedometer. Diagnostics point to a likely cable or plug connection issue with a crash sensor. Has anyone experienced something similar? Mileage is at 152659 km. This is not related to any airbag recall, or airbag deployment.

I had a similar issue with my Mercedes a while back. The SRS light kept coming on. Was it a specific crash sensor that the diagnostics flagged? Knowing that might help narrow down the possibilities. Could also be related to the seat occupancy sensor. Airbag repair can be tricky.

The diagnostic report specifically mentions a faulty connection to a crash sensor. Is this something you'd recommend attempting to fix myself, or is it best left to a workshop?

I'd advise against DIY airbag repair. My issue ended up being a corroded connector, but it took a specialist to diagnose it properly and ensure the airbag system was functioning correctly afterward. Better safe than sorry when it comes to airbag deployment. A defective cable could have unintended consequences.

Thanks for the advice. Took it to a workshop and they found a defective plug connection as suspected. Repair cost was 95€. At least the SRS light is gone now.
