How to Calculate VAG MQB AKL Sync Data with Autel IM508 IM608?

Great news! The Autel MaxiIM IM508/ IM608 now features an integrated MQB2 calculator. This means the immo software includes a built-in MQB sync data calculator, so you won’t need to rely on third-party sync data when programming all keys lost.

To calculate the sync data, you’ll need the XP400 Pro. Make sure to gather the Component Security (CS) codes from each relevant module:

Instrument Cluster: 16 bytes CS code
ECM: 16 bytes CS code
Transmission Control Unit (TCU): 16 bytes CS code (for automatic vehicles)
Kessy Module: 16 bytes CS code (if keyless entry is present)
Electronic Steering Column Lock (ESCL): 16 bytes CS code (if present)
With this information, you can obtain the sync data at no cost. Simply locate the “Calculate synchronized data” option under the MQB function in the menu.

To program VAG MQB NEC35XX or RH850/V850 keys, you’ll also need the APB131 adapter.
