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:

• 61-Battery Regulation

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.

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