Registering a new battery in your Audi Q5 using VCDS can be confusing. This guide clarifies the process for a 2015 Audi Q5 using a HEX-NET interface, specifically addressing challenges with missing Address 61 and adaptation channels.
Addressing Missing Module and Alternative Registration
A common issue is the absence of “Address 61 – Battery Regulation” in the installed addresses list within VCDS. While it might appear under the Drivetrain tab, accessing it often results in a timeout. This is because battery registration on this model is typically handled through the CAN gateway (Address 19).
Direct access to Address 61 is usually not necessary. Instead, the Ross-Tech Wiki suggests a workaround: modify the existing battery serial number by a single digit during registration. This method allows you to register a new battery even without manufacturer-specific codes. This process often works for aftermarket batteries like the EverStart AGM H8.
After this initial step, verify the new battery information using Measuring Blocks 017, 018, 019, and 020. These blocks display critical battery data like Amp-hours (Ah), Cold Cranking Amps (CCA), and reserve capacity. Discrepancies in values compared to the original battery are expected if the new battery has different specifications.
Adaptation Channels and Completing Registration
The next step involves adjusting adaptation channels to ensure proper charging and battery management. However, “Adaptation-10” found in some VCDS guides might not be present in the 2015 Q5’s CAN gateway. Instead, you’ll likely find “Long Adaptation-0A”.
The options within Long Adaptation-0A might differ from those shown in generic adaptation tutorials. Consult the Ross-Tech Wiki or official Audi documentation for the specific adaptation channels related to battery parameters in your 2015 Q5. Correctly adjusting these values is crucial for optimizing battery performance and lifespan.
This two-step process, using the serial number modification and adjusting Long Adaptation values, effectively registers a new battery in a 2015 Audi Q5 via VCDS. Remember to refer to official documentation for precise adaptation channel information for your specific vehicle.
