On the 2024-2026 Audi Q8 e-tron Electric, the Q8 e-tron can experience excessive 12V auxiliary battery drain when parked for extended periods. Despite having a large HV battery, the 12V system powers control modules, security systems, and connectivity features that remain active. A software bug can prevent modules from entering sleep mode, draining the 12V battery in 3-5 days of sitting. This leaves the vehicle unable to be unlocked or started.

This issue also affects: Audi Q4 e-tron, Porsche Taycan, Volkswagen ID.4

Common Symptoms

  • Vehicle will not unlock with key fob after sitting 3-5 days
  • Dashboard shows 12V battery warning on startup
  • Multiple module fault codes after jump-starting
  • Connected services (myAudi app) show vehicle offline
  • Clock resets to incorrect time

How to Fix

Update the vehicle software to the latest version which includes revised module sleep timing. If the 12V battery has been deeply discharged multiple times, it may need replacement as lead-acid batteries are damaged by deep discharge cycles. Connect a 12V trickle charger if the vehicle will sit for more than a week.

Typical repair cost:$0 - $400

On the 2024-2026 Audi Q8 e-tron Electric, the motorized charge port door and its locking mechanism can fail, preventing the charge port from opening or properly latching a charging cable. The electric actuator motor or the latch solenoid can fail in cold weather or after repeated use. Some owners report the charge cable becoming locked in the port and unable to be released after a charging session.

This issue also affects: CUPRA Born, SEAT Mii

Common Symptoms

  • Charge port door will not open when pressed
  • Charging cable locked in port and cannot be removed
  • Charge port door opens but will not stay closed
  • Clicking noise from charge port without door movement
  • App shows charge port error when attempting remote open

How to Fix

Replace the charge port door actuator and/or latch mechanism. In an emergency, there is a manual cable release in the cargo area to free a stuck charging cable. The actuator replacement is a straightforward repair that can be done by an independent shop if comfortable with the charge port housing.
