What this usually means
Charging faults are often charger, cable, earthing, or software handshake issues before they are onboard-charger failure. Test with another AC charger and cable first, then scan charging module faults. Do not replace the onboard charger without confirming it fails across multiple chargers.
What to ask the workshop before approving repair
- • Show the diagnostic fault codes.
- • Show photo/video proof of the failed part.
- • Give an itemised quote for parts and labour.
- • Explain why cheaper common fixes were ruled out.
- • Use/confirm: EV diagnostic scanner
- • Use/confirm: Charging cable tester
This is not a final diagnosis. It is a money-saving checklist before you go workshop.
