VW Golf (1J) Brake Electronics (MK20)

Coding

• Due to all of the Coding MK20 variants, it is recommended to use the coding from the original module when replacing the ABS module. Save the complete Auto-Scan before repairs.
• If you are having trouble finding/calculating the proper Coding please:
  • Refer to the Factory Repair Manual for Coding information.
  • Registered users that need assistance configuring the Coding can send the before and after replacement Auto-Scans to Support for assistance.
