Seat Fault On McLaren 720S – Airbag Light On | GVE London – Blog

The McLaren 720S is renowned for its exceptional performance and cutting-edge technology, but like any high-performance vehicle, it can experience issues. One common concern among owners is the airbag light activation, often linked to a seat fault.

This warning light indicates a potential safety risk and can affect the vehicle’s overall functionality. In this post, we’ll explore the causes of the seat fault and the steps to resolve the issue effectively.

Possible Issues Behind McLaren 720S Airbag Light On

Even if you take your car for regular McLaren servicing, some problems will still come up from time to time and this airbag light is one of them. Here are some of the reasons that can be causing this problem in your 720S.

• Seat Occupancy Sensor Fault – A malfunctioning occupancy sensor may not detect if a passenger is present, triggering the airbag light.
• Wiring Issues – Damaged or loose wiring connections under the seat can disrupt communication between the airbag system and the control unit.
• Seat Adjustment Problems – If the seat mechanism is malfunctioning, it can affect the sensors and lead to airbag light activation.
• Faulty Airbag Module – A defect in the airbag control module can cause false warnings, indicating a problem where none exists.
• Software Glitches – Occasionally, software updates or glitches may trigger the airbag warning light, requiring a diagnostic reset.

How to Fix Airbag Light On Seat Fault on McLaren 720S?

If you ever come across an airbag light fault in your McLaren 720S, the best option is to visit a supercar service centre like GVE London to get the issue fixed properly. However, you can even tackle this issue yourself in a few simple steps. As you can see in the video, a customer brought in his 720S which had the airbag light on at the dashboard. He was quoted 2400 pounds by a car repair centre for one of the sensors underneath the seat.

As the company doesn’t sell the sensor separately, they will have to replace most of the seats. So this client asked the technicians at GVE London to check his 720S. On taking out the seat, there was a bottle stuck underneath the seat which caused one of the wires to lose connection and open the circuit. Basically, the mechanic took the bottle out, and plugged everything in, making sure everything was safe.

On scanning the car, the airbag light fault was cleared and everything was working perfectly again. Therefore, instead of getting your supercar’s parts replaced instantly, you should first get it diagnosed properly to see if there is some other solution possible. Also, you should make sure that there are no bottles underneath or behind the seat, or in the kick panel.

Conclusion

The airbag light activation on your McLaren 720S can often be attributed to simple issues, such as loose wiring or objects obstructing sensors. Always seek a proper diagnosis before considering costly repairs.

Regular checks and awareness of your car’s interior can save you time and money while ensuring optimal safety and performance.
