Hello. First I got the light on when noone was sitting in the seat, then when someone was sitting in it the light turned off.. So I disconnected the seat and opened it to see the sensor and it was cracked. Ordered a new one from Benz immediately, was driving with passanger seat completely disconnected for 2 weeks. Today I received my new sensor and installed it, connected it but light is still on. But this time permanent, regardless if there is a passenger or not. Do you have any idea what that can be? Do I need some sort of calibration because the sensor is new ? I have not tried to disconnect the battery, just parked the car smoked a cigarette and started the work. Today after the installation the seat was connected to power for the first time in 2 weeks. Thank you for the video and possible advice.
Hi, did you disconnect the battery when you unplugged the seat sensor? If you unplug any part of the srs system the ecu logs it as an srs system fault which needs to be cleared by someone with the correct obd tool. Any time you work on the srs system always disconnect the battery. After fitting the new sensor on my car I had no warning lights, it's been about 6 months now and still all good.
@andybowie8590 Thanks for quick answer ! No I did not disconnect the battery, just unplugged all seat connectors and took the occupancy sensor out. It strange that with a faulty sensor the srs light came on and off depending on if where was a passanger or not, and now with a brand new sensor it's permanent regardless...
Great video. Thanks for posting. Very Insightful!

@@Monkeyz60593you need to clear the fault code with diagnostic tool
Andy where do you get the part from ?
Ebay. Any mercedes breakers should be able to help as long as they guarantee it works.
