Not sure this part fits your car?

Click on the green button at the bottom right side of the page and send us the chassis number (VIN) of your car and information for which part we should check compatibility. We will check it against the car maker's parts database.

Before purchase please read "FOR FOLLOWING CARS" section and compare your seat mat connector and position of the wires with our photos!!!

The seat occupancy mat is a sensor mounted in the front passenger seat. The other names of the seat mat sensor are: "Automatic Child Seat Recognition", "AKSE", "Component B48", "Front Passenger Seat Occupied and Child Seat Recognition", "SA Code U18", "9025".

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 device (like Autel, Bosch, iCarsoft etc.) to remove old errors of a broken seat mat that are stored in the airbag control unit. Once you connect the emulator your diagnostic device will be able to remove 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 an OBD diagnostic device to make sure that the SRS/airbag warning is caused by a defective seat mat. These warnings can be turned on by at least 6 sensors mounted in the passenger seat. The emulator solves the problem caused by a defective seat mat only. It will not remove the warning if description of the fault code indicates "Internal Component Fault" or "Wrong Coding" or if a different sensor is defective - in such situation the SRS/airbag warning light will still be turned on after connecting the emulator and clearing the old fault code shown 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 with a 4-pin seat mat connector and 3 wires in colors: red, white, brown which are inserted in the same position as we presented on third and fourth photo. The emulator will not work if the wires are in different colors or different position (different order) because the power wire will be in different place! The emulator will not work with cars sold in the USA and Canada!

- Mercedes-Benz SLK R171 (2004-2011)


The device is for diagnostic use only. The emulator is not a factory equipment and should only be used only as a temporary solution until you replace the original sensor. We advise you to inform all users of your vehicle about the presence of the emulator. Do not not place a child seat on the front seat! Be sure that fitting this emulator is not against any law in your country. By purchasing 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 problems on your airbag system as this is a solution for a faulty passenger seat mat only. Under no circumstances, including but not limited to negligence, shall the seller be held liable for direct or indirect damages including but not limited to harm to any equipment and/or for personal injury/death arising out of the use, or the inability to use the item sold on this website.

Shipping and delivery

1. What is the shipping cost to my location? Why the shipping costs is different that shown in the table in Delivery tab?

Shipping costs depends on 4 factors: weight of items the order, dimmensions of items in your ordery, country of delivery, city/town of delivery. Carriers have their different prices depensing on these factors and location of delivery. Delivery to remote areas and islands costs more.

Delivery time depends on your exact location and delivery method you select in the checkout. Remote areas and islands usuaylly have a little longer delivery time. Delivery time is estimated because once the order leaves our warehouse, the delivery time may be affected by many factors that are beyond our control (e.g. weather conditions, public holidays in the country of destination, border situation in transit countries, operational delays of the carrier, etc.). Delivery time presented in the delivery methods is counted in working days from Monday to Friday, excluding public holidays in the country of delivery.

3. Do you offer free shipping? When I added the item to the cart your website showed me that the shipping will be free but in the checkout page it showed me that I have to pay for shipping.

No, we do not offer free shippings. Sorry :( You have seen the information about free shipping because your browser is in "Private Mode" or you use VPN or other software that masks you IP address.

Bravissimi. Assistenza pre e post vendita Top

Fantastico, dopo anni ho finalmente risolto il problema grazie a questo sensore. Di ottima qualità. Con soli 40 euro ho risolto il problema comunissimo della spia srs e il messaggio di errore sul display “recarsi in officina”. L’ho montato io ma dopo dovete far cancellare l’errore, io l’ho fatto in Mercedes per 20 euro. Consiglio a tutti. Ricevuto in pochi giorni
