Cracked it!
This is such an easy re-code to do, literally took me 2 minutes once I found the right menu.
Made a step by step
guide if anyone is interested in doing it theirselves:
(Apologies for the crappy phone pics)
Step 1: Connect up to VCDS/VAGCOM in the usual manner, then select Instruments under the Select Control Module menu.
Step 2: Select the
Coding sub-menu
Step 3: Select Long
Coding Helper
Step 4: Select Byte 0 Bit 4.7 drop-down menu then select 10 Country: Rest of World (RoW)
Step 5: Exit Long
coding helper then hit "Do it"
That's all you have to do on VCDS/VAGCOM but now you will have to change your MFD Settings, Units menu to the correct UK format from US format (imperial to metric).
Step 6: Un-tick the Alt.speed dis to activate the "Alternative Speed Display"
Step 7: Final stage - Change your units for Consumption to MPG and Temp to ˚C.
Job Done, hope this helps!
