you must include subdirectories.

Replace:
cdb 0200 BMWM01S
with:
cdb 0200 BMWC01S

Replace:
Mk3 0103 BMWM01S
with:
Mk3 0103 BMWC01S
Do the same thing with directories 0116 y 0127.
You must include subdirectories.

Delete the following directories:
langMk2
Mk2C
Mk2m
V_2

IMPORTANT: Create the image, use the procedure related by KiwiJochen on the following thread:

Now load the v22 modified previously. You could see the update progress in your screen. Wait the eject of disc, remove it a press right knob on screen.

My mk3 doesn't ask for cd-key. Probably the mk3 OS is greater than v17. In your case you should probably try this:

Cheers.
