U.S. Dealers:
Cell modules with corrosion and battery assemblies replaced during the 93F1 Service Action must be properly
recycled, see Section E of the 93F1 Service Action Circular. Dealers must use Kinsbursky Brothers Intl. (KBI) to
facilitate the recycling of damaged/corroded cell modules and battery assemblies.
Dealers will work directly with KBI to coordinate the return of any cell modules with signs of corrosion and nondamaged module assemblies related to the 93F1 Service Action. KBI will supply dealers with the necessary
shipping labels and special packaging for the return of each damaged/corroded cell module. Non-damaged battery
module assemblies must be returned in the replacement battery packaging.
After completing the 93F1 Service Action dealers should refer to Appendix G (A3 Battery Service Action Portal
User Instructions) in the circular and do the following:





Registration (One time only)
 Visit the A3 e-tron website at https://a3.evbatteryreturns.com and register the dealership with KBI
