Possible Causes

Faulty integrated kWh meter in VW wallbox, Communication failure between meter and main PCB, Loose meter connector, Firmware incompatibility after update

How to Fix / Troubleshooting

Safety first: The internal meter is connected to live conductors. Only qualified personnel should access it.

  • Check app data: In the VW wallbox app, see if historical energy data is still visible. If new sessions show 0 kWh or ‘N/A’, the meter may not be reporting.
  • Reboot charger: Turn off the wallbox breaker for 2 minutes, then restore power and wait for full boot (1–2 minutes) before testing again.
  • Disable billing features: If your model allows charging without metering for billing, temporarily disable billing or user accounting and test a simple session.

Persistent E009 usually requires replacement of the internal energy meter module or main control board. Contact Volkswagen support; provide logs or screenshots from the app to assist diagnosis.
