On the 2023-2024 Audi Q8 e-tron, despite heavy regenerative braking, owners report faster-than-expected friction-brake wear and a returning brake vibration or pulsation under moderate braking, sometimes persisting even after rotors and pads have been replaced. The pattern points to poor rotor machining/installation or an underlying hardware/calibration issue rather than normal wear. Because the Q8 e-tron is heavy (~2.6 t), front brake components and the air-suspension are among the most expensive non-battery repairs on out-of-warranty cars. Low regen use (which leaves rotors to do more work) and rotor corrosion from infrequent friction-brake use can also contribute.

Common Symptoms

  • Steering wheel or pedal vibration under braking
  • Brake pulsation that returns after rotor replacement
  • Premature pad/rotor wear
  • Squealing or grinding from front brakes

How to Fix

Have a dealer or independent measure rotor runout/thickness variation and machine or replace rotors with correct torque and bedding-in. Verify pad hardware and caliper slides. Using a stronger regenerative-braking setting reduces friction-brake duty and corrosion. If vibration returns shortly after a full brake job, escalate for a deeper inspection of hubs/wheel bearings and calibration.

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.

On the 2023-2024 Audi Q8 e-tron, audi TSB 2071345/1 applies to 2023 e-tron and 2024 Q8 e-tron family vehicles when DC charging repeatedly fails at the same station with Plug & Charge enabled, AC charging works, the socket LED pulses white and the high-voltage charger stores U15AF00 with symptom code 2097297. Audi says some charging stations advertise Plug & Charge compatibility without the required station-side software.

Common Symptoms

  • DC charging repeatedly fails at the same station
  • Charging-socket LED pulses white
  • AC charging continues to work

How to Fix

Confirm that the failure repeats at the same station, AC charging works and U15AF00 symptom 2097297 is present. Temporarily disable Plug & Charge in the MMI or use another compatible charging station. Do not replace vehicle charging hardware solely from this symptom; follow current Audi guidance if the failure also occurs with Plug & Charge disabled or at multiple stations.

On the 2023-2024 Audi Q8 e-tron, owners report roughly a one-third loss of real-world range in winter, with in-town range dropping to around 62% of EPA figures during prolonged sub-freezing spells. When the high-voltage battery is very cold, the car limits DC fast-charge power (commonly 40-80 kW instead of the rated ~170 kW) to protect the cells until the pack warms. The large cabin's electric heater/heat pump also draws several kW in the first 10-15 minutes. This is normal lithium-ion physics plus thermal management, but it surprises owners who do not pre-condition the pack.

Common Symptoms

  • Range drops sharply in cold weather
  • DC charging limited to 40-80 kW when cold
  • High consumption (30+ kWh/100km) at highway speed in winter
  • Slower charging until battery warms

How to Fix

Use route-based battery preconditioning: enter the DC fast charger as a navigation destination so the car warms the pack en route, restoring charge speed. Precondition the cabin while still plugged in at home, use seat/steering heaters over cabin heat, and rely on Level 2 home charging (40-60A) to absorb seasonal losses overnight. No repair is needed unless range/charge limits persist in mild weather, which warrants a dealer battery-health check.

On the 2024 Audi Q8 e-tron, audi TSB 2063467/6 applies to 2024 Q8 e-tron family vehicles when a cabin noise is present only while the air-conditioning compressor runs and disappears when A/C is switched off. Audi says the supported cause may be direct contact between adjacent refrigerant lines or between a refrigerant line and the hood-release Bowden-cable clip; the bulletin does not establish universal compressor failure.

Common Symptoms

  • Noise heard in the cabin only while the A/C compressor runs
  • Noise stops when air conditioning is switched off

How to Fix

Reproduce the exact noise with the A/C compressor active and confirm that it stops when A/C is switched off. Inspect the bulletin’s refrigerant-line contact points and hood-release cable clip and perform only the branch that matches the confirmed contact. Diagnose non-reproducible noise or loss of heating/cooling separately; do not buy a battery, maintainer or portable EVSE from this card.

On the 2023-2024 Audi Q8 e-tron, owners of e-tron / Q8 e-tron vehicles equipped with the panoramic glass roof report water intrusion into the cabin, often pooling in the front or rear footwells after rain or a car wash. Documented root causes include clogged or pinched roof drain tubes (the front drain exits below the door hinge in the A-pillar), and stress cracks in the plastic water channel surrounding the roof where it meets steel-reinforced brackets that expand at a different rate. Audi issued a Technical Service Bulletin (referenced as MC-10182485-0001) covering four distinct failure modes. The issue is reported across English and German owner communities (e-tronforum, AudiWorld, the electrichasgoneaudi GitHub issue tracker, and motor-talk.de).

Common Symptoms

  • Water in front or rear footwell after rain
  • Damp or soaked carpet
  • Water dripping from headliner near the roof
  • Musty smell
  • Foggy windows / interior humidity

How to Fix

Have the dealer diagnose per the panoramic roof TSB. Repair depends on the root cause: clear or re-route clogged/pinched drain tubes, correct a pinched-shut rear drain, or replace/reseal the cracked plastic water channel. Dry out and inspect saturated carpet/underlay to prevent mold and electrical corrosion. Audi performs the repair reactively (only after water ingress is confirmed); some owners report the factory fix failing and needing a second visit.
