Good news! Autel MaxiIM IM508/IM608 (also OTOFIX IM1/IM2) now has an integrated mqb2 calculator. There is now a MQB sync Data calculator built into to immo software. You don’t need to obtain sync data from 3rd party if program all keys lost.
You will need XP400 Pro (XP1 Pro for OTOFIX) to calculate sync data.
We need CS from each cluster, ecu, gearbox (if automatic ), kessy (if keyless )
Instrument panel CS code 16 bytes
ECM 16 bytes CS code
Tcu 16 bytes CS code
ESCL (Electonic Steering Column Lock) ELV 16 bytes CS (if present)
Then you will get sync data for free.
Find Calculate synchronized data menu under MQB function.
Menu in Autel
Menu in OTOFIX
To program VAG MQB NEC35XX or RH850/V850 key, you will need APB131 adapter.
Launch X431 also has built-in sync data calculator, see:
