peugeot 206 airbag light and speedometer and stop

Hello, I have a pejo 206 1.4 xdesign 2006 model. Sometimes the airbag light comes on and the speedometer doesn't work on the road, and then the vehicle stops when I slow down. Sometimes it comes back on its own and the problem of stopping is removed, sometimes it is fixed when you stop the car and wait for a while and start it again. I mean, it's an occasional thing, but I don't understand the stopping problem, has anyone encountered this problem before? I looked at the forum and I couldn't find the problem of both the mileage indicator, the airbag light and the stopping problem at the same time, so it's something different.

Hello. Actually, the airbag light is a result, not a problem. If the speed needle goes down to zero while the vehicle is in motion, the airbag light will turn on, this is normal.

This is how we can tell if the mileage sensor is faulty. When the speed needle goes to zero, follow the odometer traveled, if the km does not progress, the km sensor is defective. For example, the needle went to zero, you are on the move, you have traveled 2 km, but the odometer does not advance, then the problem is in the km sensor.

If the km increases, the problem may be in the display or the brain.

Sir, when the speed needle goes down to zero, km does not progress, then my km sensor is faulty. Stopping occurs due to this, sir, the speed indicator goes down, the airbag light turns on, and then when you change gear or slow down, the vehicle stops. Does stopping have anything to do with it?

Then the mileage sensor is faulty.
