Hi can anyone tell me how I can get a coc for my 2004 polo as I have just reimported it back to the UK

and want a V55 log book for it. Thanks

It might be a blind alley, because the car's over 10 years old, but I'd try VW in the first instance https://www.volkswagen.co.uk/en/owners-and-services/my-car/importing-and-exporting-a-vehicle.html

There are quite a few companies out there that help with the paperwork on importing/exporting vehicles, and they can normally get them, but it'll cost £100-200
