BCM Swap (2012 Jetta)

[Uright74]

Hello Folks,

Question. Does a BCM need to be reprgorammed like an ABS module?

2012 VW Jetta 2.5

Thanks

On an MK6 Jetta, it will need to be Coded and have Adaptation channels set. Assuming the old BCM talks, get a scan for its coding and make an Adaptation Channel Map for reference.

And do not copy/paste coding for orig, byte 18 is very important to know what to do and to Code it on those BCM.

If its a kessy Car, its needs Key programming through immobilizer

Thank you. The windows and moonroof are not responding with the new junkyard BCM, but still starts runs, and the reason for this question.

Break..why can’t you just copy and paste as long as 18 drops in?

You might not want to overwrite Byte 18.

Please post an Auto-Scan for context, and tell us what functional problems you've got with it.
