Here is a way, how to find prokanal bits, since sometimes it's very complicated to find them) I don't know, maybe this method already exists on this forum.
For example:
Search:
?? ?? 68 41 2d 05 e6 f4 00 40 74 f4      1 CDLDP 2 CDEHFM

WinOLS will find the following:
A8 01 68 41 2d 05 e6 f4 00 40 74 f4
9C 01 68 41 2d 05 e6 f4 00 40 74 f4
CDLDP is 0x(8)181A8
CDEHFM is 0x(8)1819C

?? ?? 68 41 2d 05 e6 f4 40 00 74 f4       2 CDLASH
?? ?? 68 41 2d 04 e0 14 74 F4               last string CDSLS
?? ?? 68 41 2d 05 e6 f4 00 01 74 f4       1 CDKAT  2 CDHSVE
?? ?? 68 41 2d 05 e6 f4 10 00 74 f4       1 CDLSH
?? ?? 68 41 2d 05 e6 f4 00 20 74 f4       CDTEV
?? ?? 68 41 2d 05 e6 f4 80 00 74 f4       1 CDHSH 2 CDHSHE

This method works with most, but not all VAG ME7 ECUs! It doesn't work with some ME7.1.1, such as VW T5 3.2 V6 and some others. With 2.7T and 3.2 Touareg it works fine.
