How to identify your Delphi DCM3.4 file

How the numbers on this ECU type start:

• HW 32353… 11 of the 47 files with a HW number, 23%
• HW 30313… 8 of the 47 files with a HW number, 17%
• HW 23710… 7 of the 47 files with a HW number, 15%

A HW number alone does not pick the file: 3235373552 carries 11 SW versions here. Compare both numbers with your read.
