I dont know if you have heard already but seems sfd2 is now offered as beta. Any news from RT?
Yes, I'm aware that some companies are claiming they will introduce it shortly. However, I believe they are setting customer expectations too high.
We have the technical specifications, but use of SFD2 is restricted to cars that are type-approved and operated exclusively in the European Economic Area and Switzerland. So right now, we can't even test it here in North America.
With SFD2, every change to any data must be approved by VAG's servers. The tool has to send the VIN, the module address, the identifier, the existing data at that identifier, and the proposed change to that data to VAG's servers. Only pre-authorized changes will be approved with the signature from the server that is required for the new data to be written to the module. So even with SFD2 capability, the types of changes that are possible will be extremely limited.
