Solved! VVDI2 Skoda Superb 2012 24C64 No Key Found After Programming


I have s Skoda supreb 2012 which has one working smart key (orignal key MEGAMOS ID48), car push start button. Customer need another key so i program xhorse vvdi smart key with vvdi2 vag but end process in cluster dispalys 0-2.  0-2 mean no key learned still in programming mode. Key not program with near push start & original key only remote work, not ignition & not start.  I have saved original immo data from vvdi.

Than i remove odo & read nec24c64 eeprom & autel do automatic service mode & then write eeprom via obd & make cs, pin , mac. but end of same key not program.

Read 24c64 direct in PCB in a programer.
Put dump in service mode in vvdi2 and write back in the eeprom in programer.
it vvdi2 read the eeprom and then write the original eeprom previously read it the programer.
read the immo data and them write the backup you have of the immo data.

Need to learn 2 keys.
Original and new key.
You put key quantity 2
Reset instrument cluster
If it works this will allow you to restore the cluster to its original state!
You need original brand new keys or xhorse proximity key to the this job.
If vvdi prepare new dealer key them you have to add both key original and new using immo data option.

Connect the cluster on the bench with vvdi2 and do the steps above.
vvdi 2 allow direct connection to the cluster, only need connect power and ground to the cluster and CAN  lines.
