Not sure this item fits your car?

Click on the green button at the bottom right side of the page and send us the VIN of your car (17 characters Vehicle Identification Number also called a chassis number, item E on the European vehicle registration document). We will check compatibility.


The emulator is in developing stage, it might not work with all cars. Please check the "For following cars" section below.

The WSS seat occupancy mat is a sensor mounted in the front passenger seat. The other names of the WSS seat mat sensor are: "Weight Sensing System" or "SA Code: U10" or "FRONT PASSENGER SEAT WITH WEIGHT SENSING".

The emulator simulates a situation of a person sitting in the passenger seat with a seat belt fastened. To make the emulator work you need a diagnostic tool (like the latest models of Autel, Bosch, iCarsoft etc.) to remove old errors of a defective Weight Sensing System that are stored in the airbag control unit. Once you connect the emulator your diagnostic tool will be able to remove the old errors and turn off the SRS/airbag warning. Unfortunately, the errors related to the safety systems are not removing automatically.

Before purchase, please scan your car with a diagnostic tool to make sure your SRS/airbag warning is caused by a defective Weight Sensing System. These warnings can be turned on by at least 6 sensors mounted in the seat. The emulator solves the problem caused by a faulty Weight Sensing System only. The emulator will not solve your problem if a different sensor is faulty - the SRS/airbag warning light will still be present after connecting the emulator and removing the error present in the diagnostic tool.

This offer includes 2-in-1 device:
- seat mat emulator with original connector - it is marked as 1 on the second photo
- seat belt emulator with original connector (it switches off the unfasten seat belt sound and light) - it is marked as 2 on the second photo
- detailed installation instruction (with photos/videos, will be sent to your email address after we send the item) - also available here
- our technical support until fixing the problem
- 24 months warranty


Mercedes-Benz cars equipped with the WSS seat mat with the following number: A 213 870 00 10. Contact us if your car have a different part number, maybe we already developed an emulator for your seat mat too. Here's a video showing how to check the part number of the seat mat:

The emulator is intended for diagnostic use only. It is a diagnostic device designed to verify the correctness of the car's electrical installation and to determine whether the SRS/Airbag warning in your car is triggered by a defective seat mat sensor. The emulator is not a factory device. It should not be used as a substitute for an original sensor solution. After performing the diagnosis, you should disconnect the emulator and reconnect the original sensor. In the event of an accident, the passenger airbag will ALWAYS deploy (with or without a passenger in the seat) if the emulator is still connected. Do not place a child seat on the front passenger seat! We strongly advise informing all users of the vehicle about the presence of the emulator. Ensure that fitting this emulator for diagnostic purposes does not violate any laws in your country. By making a purchase, you agree that we are not liable for any damages or losses that may arise from the use of the emulator, and we are not responsible for any issues with your airbag system. We disclaim responsibility for direct or indirect damages or injuries caused by improper use of the device

Compatible with following part numbers: A2138700010
