Hey everyone,

Wondering if anyone is able to tell me if the Unitronic TCU mech swap would hypothetically work on the MK8.5 golf r?

I know the ECU is currently locked and it’s looking like it’s going to be locked for a good bit longer. As for the TCU obviously it’s locked in its current form, but would a mech swap fix this?

I know the mk8 and mk8.5 golf r share the same DQ381 Transmission, so it kind of seems like it would, but I am unsure.

If anyone knows, please let me know, as I plan on adding a JB4 onto my car and want to know if a TCU tune with a mech swap may be an option while the ECU is locked.
