This is how I did mine recently. If you want to check you are doing the calculation correctly try the example figures at the bottom.
VCDS
CODING
1.5F (Infotainment) module, Adaptations, channel: 'Confirmation of installation change'
2. Note your current
coding
3.Start Windows calculator and set it to 'Programming mode' and select 'HEX' option
4.Calculation: (current
coding) XOR C9D2
5.Change the adaptation channel to the new (just calculated) code
6.VCDS main screen, 'Auto-Scan'
7.Check for fault codes (generated by the update) and clear them (software version, interrupted communication, etc.)
8.Note that VCDS shows your code on the adaptation channel with a space ('xx xx' format).You have to remove the space before you calculate your new code. At the point you enter your new (calculated) code, insert the space again.
EXAMPLE (don't use these values):
•'1A 1A' (original
coding of the adaptation channel)
•1A1A XOR C9D2 equals D3C8
•Enter it as 'D3 C8' (with space) on the adaptation channel
•If your original code starts with zero(s) just remove them before calculating (if it's 0AFB for example calculate with AFB)
Thanks - Just tried it and I'm getting 4324 - doesnt look right to me - but maybe it is, I just dont want to enter something wrong,
Any chance you could verify for me
Thanks in advance
I get the same value of 43 24 using your 8A F6.
