Audi EV charger’s RFID card reader intermittently fails to recognize cards, requiring multiple attempts.

Safety first: This is a low-voltage subsystem; still disconnect power before internal inspection.

• Use proper technique: Hold the RFID card flat against the marked area for a full second. Avoid moving it quickly across the reader.
• Test multiple cards: If only one card is problematic, replace that card. If all cards are intermittent, suspect the reader.
• Reduce interference: Keep high-power RF devices (e.g., Wi-Fi routers, cordless phone bases) away from the immediate vicinity of the charger.
• Reseat module: With power off, reseat the RFID module connector and ensure it is firmly attached to the front panel.

If performance does not improve, replace the RFID reader module.
