Quick answer

For certain 2022–2023 US Audi e-tron GT and RS e-tron GT vehicles, DTC P05FF00 may be stored in the ABS/ESC control module when low-speed braking produces brake-pedal vibration/pulsation or an unusual pedal feel. Audi’s documented production solution was under analysis.

This page separates verified manufacturer/regulator evidence from supporting material. Unsupported causes, repairs or safety conclusions are not guessed.

1. What does P05FF00 mean?

For certain 2022–2023 US Audi e-tron GT and RS e-tron GT vehicles, DTC P05FF00 may be stored in the ABS/ESC control module when low-speed braking produces brake-pedal vibration/pulsation or an unusual pedal feel. Audi’s documented production solution was under analysis.

2. Technical explanation

P05FF00 is identified by Audi as: “Brake pressure sensor / Sensor for brake pedal travel deviation.” The documented DTC location is the ABS/ESC Control Module J104, address word 0003. The available Audi bulletin evidence states that the complaint can be reproduced; it does not establish a specific component failure or root cause.

3. What system is affected?

ABS/ESC Control Module J104 (address word 0003), with the diagnostic description referring to the brake pressure sensor / sensor for brake pedal travel deviation.

4. How serious is this code?

Unknown. The verified evidence does not assign a severity level.

5. Symptoms you may notice

  • During low-speed braking, vibration or pulsation may be felt at the brake pedal.
  • The brake pedal may feel “different.”
  • DTC P05FF00 may be stored in the ABS/ESC Control Module J104.

6. Possible causes

  • Not yet established by verified evidence. Audi’s bulletin lists the technical background as “Not applicable” and states that the production solution was under analysis.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

Not yet established by verified evidence.

9. What you can safely do

  • Arrange diagnosis by an Audi service provider if the documented brake-pedal symptoms occur or P05FF00 is present.
  • Provide the technician with the stored code and the conditions under which the symptom occurs, including low-speed braking.
  • Do not attempt high-voltage or brake-system repair based on this information.

10. Step-by-step troubleshooting

  1. Confirm whether P05FF00 is stored in ABS/ESC Control Module J104 at address word 0003.
  2. Verify whether the customer-reported low-speed brake-pedal vibration/pulsation or changed pedal feel can be reproduced.
  3. Further diagnostic steps are not established by the supplied verified evidence.

11. When to contact service

Audi service evaluation is appropriate because the documented issue involves braking behavior and an ABS/ESC-module DTC. The evidence does not establish urgency, drivability, or a specific repair.

12. What the service center may check

  • Check the ABS/ESC Control Module J104, address word 0003, for DTC P05FF00.
  • Assess whether low-speed braking reproduces pedal vibration/pulsation or a changed pedal feel.
  • Use the applicable Audi technical service bulletin during diagnosis.

13. Possible repair or resolution

  • Not yet established by verified evidence. Audi stated that the production solution was under analysis.
