Convenience bus to VAG car: Changes in 2015?

Hello guys, and sorry for speaking English, but my German is soooo bad.

'So, does anyone know if there were any changes made to VAG cars in the 2015 model year? I've used diagnostic interfaces (OBD devices) in several VAG cars, from the years 2009-2014, and they have always worked.'

Now I have a 2015 Seat Toledo, and most of the messages are the same, but the door lock control is different somehow.

Before it was ID 291, it had 5 databytes, and I could open doors with the code 00 AA 00 00 00 and lock them with the code 00 55 00 00 00.

Now, with this Toledo ID 291, I have 8 data bytes, and when I press the car's unlock button, I see the following sequence: 00 AA 00 00 00 1A 02 00.
But repeating that does nothing.
'Does anyone have any experience with very new cars? I would really appreciate hearing about it.'
