Have it inspected before further driving

Quick answer

U101882 indicates that the battery management system received a message with an invalid counter from the vehicle control unit. Power is limited to a limp-home level.

What to check first

  • Read all stored fault codes with a scan tool and deal with related codes first.
  • Check whether other modules on the same network also report communication faults; one module offline can set codes in several others.

Can I still drive?

Have it inspected before further driving. If in doubt, park the car and ask a technician — a fault that limits power or shuts the high-voltage system down will not clear by itself.
