Peugeot Expert 2.0hdi 160km - 5ff internal fault bsi the wiper goes crazy

Hello
I need help with my peugot expert 2010, after turning off the screens, they get some impulse as if they want to start and it moves slightly.
After connecting to the computer, an internal error bsi 5ff appears

Thanks in advance for the hints

Parameters you watched ?. Can you only read errors, check if the bsi sends a request for the wipers to work and then it is a commune to the bsm and from the bsm to the motor.

Or maybe it is simply obliterated

The wipers work, but when you turn them off, i.e. position 0, they still have an impulse and vibrate

Hi!
The wiper motor is probably not, but not for sure. I would take out the PSF and BSI, check for the presence of water, it will not hurt to dry it, after unplugging the connectors it is worth checking if it is green somewhere. Disconnect the battery 5 minutes before this operation and connect 5 minutes after. Internal BSI error may be related to the wipers but not necessarily, sometimes it is and everything works ok. Check if the error appears after turning on the wipers, because I understand that it can be deleted.
