Hello guys, can someone tell me if this vehicle has a belt or chain? Hsn 3003 AQV bj 2012 peugeot Boxer 185,000 km And it shows a red door as a lamp with the sporadic message (I think it’s connected with gas and brake, thereby shaking the door behind ) “Back door open r Wireless remote control close press, it only flashes a few times very quickly, but does not close. Does that depend on it? I would be happy to answer about it. THANK YOU: I just read a little bit in the net and came across a video that is a green plug. If you remove it, it will be closed. (opening also before) However, the window lifters also run over it. So you put it back in again. Unfortunately, it opens on its own again and closes the door. This is not possible again. If you try to finish : See video : As link in YouTube https://youtube.com/shorts/0qyLbdYLOok?feature=share
