MED9.5 I believe, similar to Audi RS6 and TT-RS ecu's, quite different in some ways from the earlier MED9.1 stuff.

Golf R uses the same ECU as ANY other 2.0 TFSI with MED9.1.

TT-RS and RS6 ECUs are also not 100% the same and not compatible, and they are MED9.1.2, not MED9.5.

Not necessarily, there are some differences in SOFTWARE that will not work directly, as well as hardware on the specific car, Dash, Sensors, Turbo, etc.....

Thanks for clearing that up.
Don't remember all the denominations, but TT-RS and RS6 both had a different MPC chip inside IIRC and some of the torque control was different. Some traces of MED17 were present too.
Been a bit now since I had either of those on the table.

You shouldn't do that. The ecu won't brick, but the software is very chassis specific.
