1999.5 model year cars, New Beetle, Passat, Audi

Method
Coding
1 · Before you start
Run a full Auto-Scan and save it. Write down the current coding number of 46 Central Convenience (power-window cars) or 35 Central Locking (manual-window cars) so you can put it back.
2 · VCDS
Open 46 Cent. Conv. (or 35 Cent. Locking on manual-window cars) > Coding - 07 and write down the current code.
If the code is even (selective unlock), add 1 and save (e.g. Gen 3 46: 00258 to 00259). Change nothing else.
Don't copy a code from a table unless it matches your module generation and equipment exactly (see notes).
What this changes
The same coding number also stores door count, number of power windows and memory seats. Adding 1 to the car's own code changes only the unlock mode. Typing a code from a table for the wrong generation or equipment replaces those settings. For example, 00258 on a Gen 2 comfort module means '2 power windows + memory seats', not '4 doors / 4 windows'.
