Video tutorial

In this video, see how resetting the BSI unit fixed the issue the YouTuber had with the Peugeot 107: at startup, the vehicle indicated a fault with the emissions device. To perform this operation, you need an advanced OBD11 reader to read the various error codes.

Once it was found that the problem was the wiring not connecting properly to the coils, and the connection was redone, the YouTuber proceeded with a BSI reset. Lower the driver's window, lift the bonnet, close the doors, disconnect the battery, and wait for 15 seconds.

Reconnect the battery and wait another 10 seconds. Through the window, turn on the side lights and the dashboard (opening the doors is not permitted).

Now clear all errors and take the vehicle for a drive: no errors will be returned.
