On the 2020-2024 Audi A6 allroad, audi TSB 2067906/5 explains that the 48V battery can enter low-state-of-charge protection and open its internal relays. P0A7D00 can accompany this condition. When measured 48V state of charge is 5%-15%, Audi directs a controlled recharge through the 12V electrical system and says the 48V battery must not be replaced for that condition. P0B2900 alone is also not a reason to replace the battery. This is a guided service procedure, not proof of battery degradation.

Common Symptoms

  • 48V battery state of charge at 5%-15%
  • 48V low-state-of-charge protection active

How to Fix

Have an Audi-trained technician measure both battery states of charge and follow the current guided procedure. For a 48V battery at 5%-15%, TSB 2067906/5 requires an approved high-capacity 12V charger and the ODIS charging-contactor test plan; it is not a consumer battery-maintainer procedure. Audi permits replacement only when the 48V state of charge is below 5% or guided fault finding directs replacement. Do not buy a 48V battery, 12V battery, charger, tape, wire loom or connector kit from this diagnostic card.

On the 2020-2024 Audi A6 allroad, audi Service Action 27BQ includes certain 2020-2024 A6 allroad vehicles equipped with a 48V belt starter-alternator. Audi states that an affected unit can inhibit the start-stop function and increase emissions while the vehicle is stopped, while emissions remain within legal limits. Model year alone does not establish eligibility: the VIN must show 27BQ open in Audi Elsa. A general electrical-system warning or a stored communication code does not by itself prove that the starter-alternator has failed.

Common Symptoms

  • Start-stop function unavailable on a VIN with Service Action 27BQ open
  • Electrical-system warning requiring Audi guided diagnosis

How to Fix

Check the VIN and current open-action status with an Audi dealer. If 27BQ is open, Audi directs the dealer to replace the 48V belt starter-alternator at no cost under the service action. If the action is not open, use Audi guided diagnostics before replacing parts: TSB 2058831/15 ties replacement to its defined C29/B200096 test result, while TSB 2073284/3 identifies sensor and CAN faults for which starter-alternator replacement will not fix the concern. Do not buy a starter, alternator, 12V battery or charger from this campaign card.
