How to use VAG COM for Passat 3C ABS coding

A c3/passat 2007 came into my place and the ABS module lost its coding without any reason.
Initially the code was 000001, I did some research and tried several codes copied from autoscans but none of them worked, (control module incorrectly coded).

The best and fastest way to find a solution is doing the SVM directly with a dealer but if you don’t want this, Rosstech has support for licenced interfaces.

So I did an autoscan of the passat (which is attached), and was told the coding: 46523

The “control module incorrectly coded” was gone but now the module was asking for a vacuum sensor “02543 Vacuum sensor for brake booster” but my passat wasnt equipped with that sensor.

The 46523 in binary would be 1011010110111011
The most significant bit in that binary number is 32768, not 8192….. so the correct would be 46523-32768=13755

decimal to binary
46523d=1011010110111011b

each digit has its value (check binary to decimal conversion). the one at the very right is the least significant bit and the one at the very left is the most significan bit (MSB)

The image ends with 8th digit = 128 but the 16th digit would equal 32768….. and disable it would mean change the binary number to 0 0 1 1 0 1 0 1 1 0 1 1 1 0 1 1… and than number in decimal is 13755

13755 worked perfectly, so for sure the most significant bit enables or disables the needing of that sensor.

Hope it helps
