P2E97 Charge Port Door B Open Request Switch Circuit Intermittent/Erratic

P2E97 points to a request signal from charge flap B that briefly vanishes or jumps, while no permanent fault can be found. A real case with the same sensor type comes from Porsche: on the Macan Electric of model years 2023 to 2025 the optional electric flaps open when a flat hand rests on the rear third, and bulletin WRP7 explains that production tolerances could make the gesture go undetected now and then; the fix replaces the adhesive strips that hold the sensors on both flaps. No manufacturer links that case or any other to P2E97 publicly. Electrically, loose terminals, a harness bent by the flap and a poorly fixed sensor are the usual reasons. Permanent faults are coded as P2E93, P2E95 and P2E96. Drivers notice a flap B that responds only sometimes.

Likely causes

Symptoms

• Flap B opens only on some attempts
• Code stored without a lasting fault in the workshop

Repair estimate

Typical range across vehicles; the real cost depends on what the testing finds.
