P2E94 code meaning
Charge Port Door B Open Request Switch Circuit Performance
What P2E94 means
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.
P2E94 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.3 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2E94
- 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
Common causes of P2E94
- Most likelyDeformed or recessed flap B keeping the request button pressed
- PossibleSensor of flap B shifted or not seated correctly
- Less likelyIce or dirt acting on the sensor area
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E94 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 94 | The exact fault in that area. |
What to do next
- Note P2E94 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2E94
What does P2E94 mean?
P2E94 means "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. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E94?
P2E94 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2E94 fail an emissions test?
P2E94 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P2E94 to fix?
Difficulty: medium. A typical repair takes 0.3 to 2.5 hours of work. This is a job for a workshop.
Will P2E94 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
