VAG OBC (On-Board Charger) Specialist
The on-board charger converts AC power into DC to charge the high-voltage battery. When it fails, the vehicle may show “charging not possible”, refuse to charge at home or public AC points, or log internal charger fault codes.
We specialise in VAG group OBC diagnostics and repair across London, covering Volkswagen, Audi, Skoda and Seat electric and plug-in hybrid models.
- AC charging not working
- “Charging not possible” messages
- OBC internal fault codes
- Charger communication and isolation faults
- Post-repair coding and adaptation
Why Repair the OBC Instead of Replacing It?
VAG dealers often recommend full on-board charger replacement. That can cost thousands and involve long delays.
We use a traditional diagnostic approach — confirm power, cooling, communication and internal charger faults, then repair or restore the unit where possible.
