Hi! I am using VCDS 17.8 and HEX-V2 cable on vw passat NMS 2015. Trying to code BCM, byte 18, and car just ignores coding. After I change Byte 18 in (09-Cent.Elect) I press "Do IT" then I get confirmation about coding done. Press OK, but this do not affect car at all. (all doors closed and unlocked) Tried programming with only ignition on, and with engine running.
Also, VCDS throws some errors: EV_ECM18<...>()VW41 unable to find a .ROD file.
Obviously I am trying retrofit rear tail lights, to add amber turn signals. Main question, why car just ignores coding, and software says everything is OK, coding changed.
Cheers,
