Can some plz tell me what “WMJ6” refers to? Was interested in a CPO 2020 C2S and this shows up on the Carfax report.

Also why is Carfax not showing any history prior to 2021? I mean it’s a 2020 model and the first one that shows up is

11/11/2021

• Porsche Cars North America

• Manufacturer Voluntary Service Action issued
  • Program #WMJ6 RE-PROGRAMMING AND/OR CODING SEAT
  • CONTROL UNIT.

Could this be a dealer buy-back? Thanks in advance.
