P2E9ECharge Port Door B Unlock Control Circuit Performance

  • Generic OBD-II code · Powertrain
How the car detects it
P2E9E is a function check: the control unit commands flap B to unlock and then expects the position sensor to confirm an open flap. GM's tables for the A flap of the Volt set P0CD2 when that report is missing after 5 seconds (2011) or 13 seconds (2013, only above minus 12 °C), skip the test while position or output codes are active, and use Type B. No manufacturer documents P2E9E publicly, but Audi bulletins show the mechanical side on two-flap cars: on the e-tron the flap lock actuator can break if the flap is forced (2080912/1), on the Q6 e-tron broken gears in the flap motor leave it rocking at one spot (2077931/1), and on the A6 e-tron software could release the second flap's lock before the first was fully shut (2079918/1). P2E9D covers the electrical circuit.
What you may notice
  • Flap B pops slightly or rocks but does not open fully
  • Flap B moves freely by hand because the actuator is broken
  • Charging flap warning, charging only on the other side
Likely causes
  • LikelyFlap B lock actuator or motor gears broken, often after force on the flap
  • PossibleFlap B frozen, dirty or binding in its housing
  • PossibleSoftware sequencing error between the two flaps
  • RarePosition sensor not reporting the opened flap
