Good to know
Fault codes follow Bosch's standard numeric format (e.g., 430, 503, 504); the sources reference Bosch's official error code documentation but do not provide a full table specific to the PX — common codes like 503 (speed sensor error) and 504 (manipulation of speed signal) apply across Smart System drives.

Same number, different meaning. Error codes are not standardized between manufacturers — the same number can point to different faults on other systems. Always confirm your drive system first, or compare all systems.
