I'm about 1.5 hours or so from you in Derbyshire so not that close but if you have an old laptop running Windows XP you can just use this one from Aliexpress with the software included on the CD (dated from 2011 but fine for my Mk8 and definitely fine for your Mk7)

You may be able to find the same cable for cheaper I just thought i'd link to the one I have as it definitely works
There is also a way to use newer software on Windows 11 using this cable following the instructions here - apologies the thread isn't the easiest to read but there is someone in there who posted a REG file and some instructions
