Modern Vespa

Hi ,
Any idea ?

when locking is active, a very long noise for around 30-40 second than short cut noise than again 30-40 sec…

The locking system working good except noise.
Engine not limited up to 8000 RPM
thanks in advance

It is hard to see in the video, but it appears that the hydraulic reservoir is empty.

If not, check the pressure sensor. Otherwise, the fault probably lies in the motor or parking module.

thanks for response,

No, The level is full,
it is hard to see because I just flush the old DOT4 oil, and the new fresh oil is almost clear...

failure has been found, it is the potentiometer of the tilt system.

By the way, it is very easily to find it, the middle wire of the potentiometer need to be 4V or 1V between lock or unlock.

Thanks for support

Well found, and thanks for posting the solution.
