TSB: Power Supply Flap (Charge Port Door) Malfunction - April 7, 2025

[Tooney]

Concerns: Electric charge port door (M-no. 2W9) Power supply flap (charge port door)

Cause: The customer complains that the charge port door cannot be opened/closed or does not open and/or close completely. The warning message“Charge port door impaired on the left” or “Charge port door impaired on the right” is displayed on the instrument cluster and the vehicle cannot be charged.

Information: Taycan vehicles are equipped with the “cross-lock” safety function.
This safety function automatically locks the opposite charge port door when a charge port door is opened, so that only one charge port door can be opened at a time.
For this reason, it is possible that a malfunction of the left charge port door may lead to the warning message
“Right charge port door impaired” in the instrument cluster and vice versa. As a result, both charge port doors
must always be checked for possible malfunctions.

Action: If there is a customer complaint, even if only one charge port door is displayed as faulty, check charge port door on the left and right.

Mine has stuck 1/2 closed about 2-3 times. The "hold it open" trick has worked to get it completely closed.
Really wish they had kept the manual charge door as an option.

Seems like the "cross-lock" safety could be accomplished by electrically disabling the port not currently in use.

Yep, I had this i January, they replaced right door module and then noticed PIWIS was also showing left side out of spec so replaced that too. Before the failure my port doors would not automatically close after being left open for about a minute. They now do.
