P0D94 is the functional check of the locking step: the wiring tests fine, yet after a lock command the feedback from the actuator does not confirm that the pin arrived in its locked position. Two makers publish it. Ford's TSBs 22-2355 and 23-2014 tie it to a broken or missing pin in the DC charge-port lock actuator of 2021–2023 Mach-E, e-Transit and Lightning models, cured with a new actuator. Audi logs P0D9400 in charger J1050 (address 00C6) of 2024–2026 Q4 e-tron models: the plug at times neither locks nor releases, the charge LED switches to red and the cluster reports restricted AC charging. Audi blames charger software, warns that a new control unit does not help and fixes it with the combined update ID.S 5.6.3 (TSB 2083187). Electrical faults are P0D91–P0D93.

Likely causes

Locking pin broken or missing (Ford)
Software fault in the on-board charger, fixed by update (Audi)
Actuator mechanism binding from dirt, ice or wear
Charge plug not fully seated, so the pin cannot engage

Symptoms

  • Charging aborts or does not start; DC fast charging unavailable
  • Charge cable cannot be removed except with the manual release
  • Charge LED changes from green to red, AC charging restricted message (Audi)
