Audi CAN Gateway Battery Coding (8T/8K/8R+)
General Information: Most 2009+ Audi A4 and newer models do NOT use a separate 61-Battery Manager. In these cases battery management is a slave (subsystem) under the 19-CAN-Gateway control module. This page covers those 8T/8K/8R and newer models using a CAN Protocol 19-CAN-Gateway control module.
If the vehicle in question uses a diagnostic capable 61-Battery Regulation controller this page should apply instead:
Long Adaptation
Installation of a new battery requires the use of the [Long Adaptation-0A] function under 19-CAN-Gateway control module. Follow the onscreen instructions to enter the Part Number, Vendor, and Serial Number all as one long new value.
Prerequisites:
- New Audi Battery Installed
- Aftermarket batteries may NOT have a valid Audi Part Number, Vendor code or Serial number. Ross-Tech cannot offer assistance if the necessary information is missing.
- Key On, Engine OFF

VCDS will populate instructions in the form of a pop-up balloon with the formatting. For example:
Format: NNNNNNNNNNN XXX ZZZZZZZZZZ N = Battery Part Number (11 Digits) X = Battery Vendor (3 Digits) Z = Battery Serial Number (10 Digits)
[Add to Log] Saving the original value to a log is strongly recommended.
Type the New Battery details into the New value field.
- Note, the New value must be 26 (alpha numeric) total characters including the spaces! If in doubt check the saved log for the original battery formatting details.
[Test]
[Save]
Providing the value was accepted by the controller the new battery coding is complete.
[Done, Go Back]
[Close Controller, Go Back - 06]
Note: The 10 digit serial number may be preceded by the Battery Vendor Code, for instance VA0. See examples below:
