The VAG MQB All keys lost immo and sync data services slowly shut shop as VAG crack down.
Reached out to one of the sellers of MQB sync data and it seems they don’t have access to it anymore. Now they are asking to give them the ECU CS.
If CAR is without keyless wich means No elv on car you can read ECU TCU AND DASH and Make key .
If keyless go it have ESL wich means there is no tool to read ESL and you will not be able to make dealer key and to learn to the car.
This is at this moment.
Launch X431 IMMO Plus/IMMO Elite can calculate sync from CS of the various modules has been possible for quite some time. There’s even PC-based calculators out there once you have the CS from all the modules. It’s also a lot of bloody work, getting at the TCU in the car is an absolute pain, and removing it even worse because you’ve got to drain the transmission to do it. Also they haven’t addressed the issue of keyless vehicles where the ELV is also immo related and must be read, and no tool supports recovering the CS of the ELV.
We need CS from each cluster, ecu , gearbox (if automatic ), kessy (if keyless )
Input
Instrument panel CS code 16 bytes
Ecu 16 bytes CS code
Tcu 16 bytes CS code
ELV 16 bytes CS (if present)
Then you will get sync data for free.
We have been told by unreliable sources that if you have all the other modules CS it is possible to recover the ELV by calculation but we don’t know how long that takes having never seen the procedure.
