Faulty BMW Seat Occupancy Mat – Causes and Fixes

by Jan 15, 2023TPMS Bypass

BMW is one of the most popular car manufacturers in the world. They are known for their luxury vehicles and motorcycles. However, even with BMW’s stature and popularity, they can still experience some issues when it comes to manufacturing. 

One issue that has plagued BMW vehicles is their faulty seat occupancy mat. In 2008, BMW recalled 200,000 vehicles due to a front passenger seat electronic sensing mat failure. This was repeated in 2013 when BMW recalled over 76,000 vehicles and in 2015, when BMW also recalled over 90,000 Mini-Coopers due to a similar issue. While BMW has tried to fix these issues in their vehicles, it seems that the seat occupancy sensor malfunction in BMW vehicles is a recurring problem.

What Is the BMW Seat Occupancy Mat?

The BMW seat occupancy mat is a system that detects if someone is sitting in the passenger seat. It does this by sensing the movement of the seat and body weight on the seat. If there’s no one sitting in the passenger seat, the system disables the front airbag for this side. This is also the case if a child is on the passenger seat. If the seat occupancy sensor detects that a child is on the passenger seat, the front airbag will not deploy to prevent any serious injury on the child. 

How Does the BMW Seat Occupancy Mat Malfunction?

As with most things in life, this system isn’t perfect and can fail from time to time. Unfortunately, it sometimes fails without warning. The problem is that If the seat occupancy mat sensor malfunctions, it will disable the front air bag. This means even if there’s someone seated on the passenger seat, the air bag will not deploy. This error can lead to serious injuries or death.

What Are the Possible Causes of a Seat Occupancy Mat Malfunction?

The seat occupancy mat is located under the passenger seat. One of the possible causes of malfunction is due to water damage. If water gets into your vehicle through your windows or if you drove through some flood waters, it’s possible that there could be a water leak inside your vehicle that can damage some of your vehicle’s parts. This can lead to grounding or electrical malfunction that can affect your seat occupancy mat.

Another possible cause is if your vehicle’s battery is running low. If your battery already has low voltage, it’s possible that not enough electricity or power is reaching the passenger restraint system which may result in the seat occupancy mat malfunctioning. Low voltage can also be caused by a bad fuse or wiring.

The most common cause of a seat occupancy mat malfunction is a faulty passenger airbag sensor which is underneath the passenger seat. You will need to have the sensor replaced for it to function properly.

Lastly, it’s also possible that your seat occupancy mat has been damaged and needs replacing with a new one supplied by BMW dealerships worldwide.
