How to change FM radio frequency range on Audi concert II head unit?

General

Hey guys,

I have a Japanese Audi TT mk1 225, and I’m looking to change the frequency range/radio region on the Audi concert II. In Japan, the FM radio frequency range is 76 to 95 MHz, which means I can only tune into that frequency range. Unfortunately, this restricts me from accessing most radio stations in my area. Does anyone know how to adjust this so I can tune into higher frequencies?

There is some radio coding you can do with vcds or obd11, but not sure if it will do that

If you can’t change the region coding with e.g. vcds, I’d suggest getting a unit from your region and fit it.

It’s tricky to find a replacement for the MK1 TT because the Audi concert head unit in it is slightly different from the Audi concerts in other models from the same time. I’ll try messing around with VCDS to see if I can sort it out.
