This area has some problem with data, the routings are not correct. 

If I use this route it works : 
https://www.openstreetmap.org/directions?engine=fossgis_osrm_car&route=-23.62830%2C-46.87320%3B-23.63530%2C-46.86850#map=17/-23.63180/-46.87138


But it does not work for any other engine : 

https://www.openstreetmap.org/directions?engine=fossgis_osrm_foot&route=-23.62830%2C-46.87320%3B-23.63530%2C-46.86850#map=16/-23.6354/-46.8748

The area has gates, but it work fine only for  OSRM car routes
