Method
Long coding + Adaptation
1 · Before you start
Run a full Auto-Scan and save it. Copy the whole long coding string of each module you change, and write down or screenshot each adaptation value before you change it.
2 · VCDS
Preferred if available: open 46 > Adaptation - 10. Set channel 004 'Auto-Lock' to 1 (0 = off) and/or channel 005 'Auto-Unlock' to 1 (0 = off), then save.
If the channels aren't available, open 46 > Coding - 07 > Long Coding Helper and tick 'Auto-Lock (automatic locking from 15 km/h)' and/or 'Auto-Unlock (unlocking after removing key from ignition)'. vag-coding.net (Golf 5) shows these as Byte 0 Bit 4 and Byte 0 Bit 3. Save.
Notes
Channel 003 on the same module is 'Selective (Single) Door Locking'. Don't change it by mistake.
