2021-2024 Audi e-tron Ghost DTCs in HV Charger ECU

Frequently Asked Questions

What are "ghost DTCs" in my Audi e-tron?

Ghost DTCs are Diagnostic Trouble Codes (DTCs) that are erroneously stored in the high-voltage battery charger control module (J1050) due to a software diagnosis issue. These codes, such as B200000, P0CA400, and U112100, do not indicate an actual fault with your 2021-2024 Audi e-tron or e-tron Sportback and are considered normal.

Should I be concerned if my Audi e-tron has DTC B200000 or P0CA400?

No, if you are not experiencing any actual charging issues, these DTCs are considered ghost codes and can be ignored. Audi TSB 2062631/5 clarifies that these codes are a result of a diagnostic software issue and do not require any repair or part replacement.

What should I do if my Audi e-tron has actual charging problems?

If you are experiencing genuine charging concerns, this TSB does not apply. You should have your vehicle diagnosed by a qualified technician following the Guided Fault Finding procedure to address the actual problem. Do not assume the issue is a ghost DTC if you have noticeable symptoms.

Does this TSB 2062631/5 cover warranty repairs?

No, Audi Technical Service Bulletin 2062631/5 is informational only. It clarifies that the presence of these ghost DTCs is a normal condition and therefore not applicable to any Audi Warranty claim.
