MQB license works for odometer as well.
Sync data is just for IMMO of course. Sync data is for dealer key generation.
The whole dump is encrypted and the processors are locked. But for odometer you don’t need sync data. The servers of VVDI/AVDI and the other tools decrypt the dash/immo data but they cannot get the sync data which is only stored in the working key.
So currently you have one option to get the SYNC data (when key is missing) – use paid service to get it from VAG server. Soon there may be a second option – to generate the SYNC yourself by reading all the computer modules in the car (ECU, DASH, ELV, Transmission…) but for the moment there’s no tool which can read the ELV if fitted.
