Noob question about DSG unlock on a Cobb AccessPort

[RAD GTI 1984]

Hey guys, im about to make the jump from APR to cobb AP because APR discontinued their stg 2. Problem is, I'm a complete newb to accessport, and was hoping you guys could help me answer a few questions.

Looking around for a used unit to ideally save some cash. Found one with some 5150 tunes on it (DSG and ECU), but don't know if I will be able to use them. Any general tips for me when purchasing a used unit? anything specific to look out for? Thanks everyone!

Make sure it’s been unmarried from the original vehicle. If the 5150 dsg tune doesn’t match your transmission code it won’t work but you should be able to load the Cobb files.
