Battery Replacement

A large majority of modern VW/Audi/Seat/Skoda vehicles require the configuration of replacement batteries. The diagnostic steps vary depending on the actual vehicle configuration.

Prerequisites:

• New VW/Audi Battery Installed
  • Aftermarket batteries may NOT have a valid Part Number, Vendor code or Serial number. Ross-Tech cannot offer assistance if the necessary information is missing.
• Key On, Engine OFF

Long Adaptation

Installation of a new battery requires the use of the [Long Adaptation-0A] function under 19-CAN-Gateway control module. Follow the on-screen instructions to enter the Part Number, Vendor, and Serial Number all as one long new value.

[Select]
[19 - CAN-Gateway]
[Long Adaptation-0A]
Channel 004
[Read]
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]

Special Notes

• Measuring Block groups 008, 019 and 020 should show Battery information.
• Registered users encountering difficulty can contact us via email -or- join and post in our forum. Please include the Auto-Scan, Saved Adaptation Channel 004 Log prior to modifications, the part number, serial number and vendor code located on the original battery and the details located on the brand new battery in addition to the error message details.

Notes

• Users encountering difficulty with the data shown on the battery sticker may want to:
  • Consider scanning the QR code with a smart phone app. We have had success with BB, Android and iOS platform mobile devices running i-nigma's free app.
    
  • Refer to this B8 A4 Battery Replacement - Coding thread which discusses labels in some detail.
  • We have seen some cases where (contrary to established norms) some Varta batteries have VAO (letter O) instead of VA0 (number 0). If you encounter a problem with Coding one of these, please try substituting the letter for the number or vice versa.
