In plain English: The small locking pin that secures your charging flap (fuel filler flap for hybrids) isn't working correctly. It may be stuck open, stuck closed, or failing to latch.

The description points to the "Message Fuel Cap Lock Status." Basically, the car is confused about whether the fuel door is locked or unlocked, and I’m getting a warning on the dash. I’ve checked the fuel cap itself and it seems tight, but the error keeps popping up.

Symptoms you may encounter

• Intermittent or permanent warning lights on the dash (ABS, airbag, service messages, or general warning).
• Loss of specific functions (central locking, keyless start, windows, seat memory, ADAS features, or multimedia failures).
• CAN-bus communication errors, modules going to “sleep”, or modules not responding to diagnostic tools.
• Errors appearing after battery replacement, jump start, or after installing third-party equipment.
