Modern Vespa

I have a reoccuring problem that points to a fault in the front hydraulic system, when activated the horn sounds 5 times.
This seems to come and go. the last time it went into the shop as it first started 3 days out of warranty they told me that they bled the system and reset it, it was fine for around 6-8 weeks but did it again yesterday. rode it today and it was fine.

just wanted some pointer of what to look for first I am guessing I am looking for a leek somewhere.

also if I bleed the system is there a way to reset it?

Pull back the rubber end caps on the hydraulic cylinders (the ones down by the locking rods on the front end) to see if either one is wet. If one or both are wet, the wet cylinder(s) is going bad.

took off front end today and the main res is nearly full so I am guessing no leak

Could even be a duff pressure switch (or connection to it) - but that's unusual. Could be a duff pump valve allowing fluid to drain back. You don't have to leak much fluid to have the pressure drop - as it's 'incompressible'.
