2011 Jetta. Need to add key. Do I need to delete immo ?

I know Tcode allows you to add 1 key with out erasing others. So erase all is Not required.

Is that what your asking?

Yes. But I'd I want to add more keys for example than I need to erase immobilizer ?

Id say safer to just add one at a time unless all keys lost.

You can add 8 keys total to VW (VDO NEC).

No....

Service mode if using AVDI. Takes 60 seconds, or the car never starts again. One of the two.


Never used TCode for these.

I wasnt thinking of it being nec cluster but in that case:
tcode does have new cable for them to enter service mode and add keys But I havent tried it yet.


id reccomend saving abs coding with vcds and eeprom a backup up from 24c64 first.
