P2E94 Charge Port Door B Open Request Switch Circuit Performance

With P2E94 the open request input of charge flap B is electrically sound, yet its behaviour cannot be right, for example a request that stays active for far too long. Audi describes exactly this pattern for the Q6 e-tron in bulletin 2076776/1: tension in the left or right flap module can deform the flap so that it sinks into the body and the button inside the module stays pressed; the flap can then no longer be opened from outside, while the display still opens it. No manufacturer ties this to P2E94 publicly. CARB 13 CCR 1968.2 (e)(15.2.1) asks for rationality checks on inputs where feasible and for separate codes from circuit faults, which is the role of this code next to P2E93, P2E95 and P2E96. A GM patent shows the basic chain: release button, controller, latch actuator.

Likely causes

Deformed or recessed flap B keeping the request button pressed
Sensor of flap B shifted or not seated correctly
Ice or dirt acting on the sensor area

Symptoms

  • Flap B cannot be opened from outside
  • Opening via the display or charging menu still works
  • Flap B sits deeper than the surrounding body panel
