C100004 — ESP internal hardware fault
Quick answer
C100004 indicates that the ESP module has detected an internal hardware fault in its own electronics, so the stability system may not work when it is needed.
What to check first
- Read all stored fault codes with a scan tool and deal with related codes first.
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.
