Replacement

• Run and save a complete Auto-Scan and save it prior to module removal. See the Online Manual Auto-Scan.
  
• Code the new module with the Coding from the original module found in the Auto-Scan.
  
• Clear fault codes and verify all functions are working as per design.
  

Note, If the replacement module uses a longer coding length you cannot copy and paste the original coding directly into the replacement module. This example is from a 2006 Passat:

Original module

Address 09: Cent. Elect.        Labels: 3C0-937-049-23-H.lbl
  Part No SW: 3C0 937 049 Q    HW: 3C0 937 049 Q
  Component: Bordnetz-SG     H46 1501  
  Coding: 14848F0340041A00470A00000F00000000285D435C0000

Replacement Module

Address 09: Cent. Elect.        Labels:. 3C0-937-049-30-H.lbl
  Part No SW: 3C8 937 049 AC    HW: 3C8 937 049 AC
  Component: Bordnetz-SG     H64 3205
   Coding: 008C0F000004100040000000000000000000FF0F5C004800000000000000

In that example, you would use the original coding and add 14 zeros to the end. That will convert the original 23 Byte (46 digit) to the new 30 Byte (60 digit) coding format needed for the replacement module.

14848F0340041A00470A00000F00000000285D435C0000
14848F0340041A00470A00000F00000000285D435C000000000000000000

The last coding string in the above example would be accepted by the 3C8 937 049 AC module.
