1. What does C051F00 mean?

For certain US-market 2019–2023 Audi e-tron vehicles, C051F00 is documented by Audi as “Multi-axis Acceleration Sensor Module ‘A’ Correlation” and may be stored sporadically in the ABS control module (J104, address word 0003). Audi service communications identify software updates as the documented remedy for covered conditions.

2. Technical explanation

Audi documentation associates C051F00 with the ABS control module J104 and describes it as a multi-axis acceleration sensor module correlation fault. One 2019 Audi communication states that, on 2019–2020 e-tron quattro vehicles, a small timing window during entry into sleep mode could cause the condition. Later Audi communications state that a software update was needed to address the concern and that updated software was implemented in production.

3. What system is affected?

ABS control module J104 (address word 0003), with the DTC description referring to the multi-axis acceleration sensor module.

4. How serious is this code?

Unknown. Verified evidence does not establish a severity classification for this DTC.

5. Symptoms you may notice

  • Multiple warning lights in the instrument cluster.
  • ESC warning light on.

6. Possible causes

  • For 2019–2020 Audi e-tron quattro vehicles covered by Audi communication A4519132055702/1, Audi describes a small timing window while the vehicle enters sleep mode as the technical background.
  • Audi later documented that a software update was needed to address the concern.
  • Other causes are not yet established by verified evidence.

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 with an authorized Audi service provider or qualified repair facility.
  • Provide the stored DTC and ask the service provider to check applicable Audi software updates and service communications.
  • Do not attempt high-voltage or module repair procedures yourself.

10. Step-by-step troubleshooting

  1. Confirm whether C051F00 is stored in ABS control module J104 (address word 0003).
  2. Check whether the DTC is sporadic, as described in Audi communications.
  3. Have a service provider check applicable software version management (SVM) updates in accordance with Audi procedures.

11. When to contact service

Service is appropriate because Audi’s documented remedy involves a software update performed using Audi service procedures. Verified evidence does not establish an immediate driving or charging restriction.

12. What the service center may check

  • Scan ABS control module J104 (address word 0003) for C051F00.
  • Check for the associated warning-light condition documented by Audi.
  • Review applicable Audi software updates and SVM instructions.
  • For the 2019–2020 e-tron quattro communication, assess whether related codes C052000, C102229, C102029, or U015100 are present.

13. Possible repair or resolution

  • Audi communications state that a software update was needed to address the concern.
  • Audi instructs service personnel to follow TSB 2011732, “Software Version Management (SVM), operating instructions,” for the update process.
  • Updated software was implemented in production, according to the cited Audi communications.
