I'm posting the backup of a KOMBI CAFD from when I got my M5 last summer, before I started coding. The dealer reflashed the whole car before putting it up for sale to whatever the I-step for 7/2017.
The key you posted doesn't look like what you need, because both the M5 and my F10 550i have the same werte value. I am afraid that the 0xC8 = 200 is just a ringer.
FWIW, my guess would be that 160 vs. 200 isn't your problem. I think the KOMBI just has a PT-CAN bus connection, and no direct feed from any pulse sensor in wheels or diff, I figure it would just receive digital speed data (pulses or decoded velocity) from ICM or somewhere else. Even if the KOMBI was getting just a pulse count, the count would be based on wheel size regardless of car or M/non-M, so it could be your speedo difference is really because the M and non-M cars had different wheel sizes coded, and it is displaying the "correct" speed for that wheel size. Something to look into to chase it down.
Good luck!
