Answer 1

Already read the question, and had no idea ready. But since you've asked me to check it out, I'm going to give it a shot. You send the command 09 02 right?

You can check with command 09 00 which commands in the VIN-mode (09 xx) are supported. You will get this bit-encoded answer from the car, and with that answer you can check if 09 02 is supported. (If you need help with the bit-encoding, please ask help, but it's not very hard with some googling). Looking forward if this match with your 09 02 reports.

Most likely it will not be supported, and that will be the problem.

I believe there is no AT command available to get the VIN, you need to use mode 09.

Edit 1: Now I'm thinking about it, and it could be protocol related, but I have to do way much google-work to find that out. Might be an option to find out which protocols work for your VIN-reading.
