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.

[Save]

Providing the value was accepted by the controller the new battery coding is complete.
