The hydraulic system alarm has been a pain on one of my 500s for a while now.
It seems no one else has these issues but me ( and I use the hydraulic lock very sparingly). But both 500s have this problem to some degree.
As mentioned in my previous post, I just today had the mechanics disable the alarm system, and plug the sensor ( the source of the leaking despite having new ones mounted) as all other things seemed right and it just kept honking. Piaggio didn't know what the deal was either.
Just wanted people to know that disarming it is an option if you run into trouble with it.
It will require a bit more attention from us, ( we never leave it locked and not also on the stand anyway) but the bike is back home and
I think we can get on just fine without it.
