I'm from Denmark and proud owner of this '95 GTI:

I'm also joined on the axownersclub.com and have asked the same question on their forum.
The problem is that Denmark is a very strict country when it comes to cars and tuning them and I really really want a 16v lump in my beast

Here in Denmark I need an approval/certificate from Citroën before I can do my project. Citroën has denied me this approval and now I'm searching for this certifcate other places. So afterwards I can say to Citroën, that other Citroën dealers (or similar places) in other countries have approved this project, and maybe they will approve my project.
Do any of you have such an approval lying around ?? And be willing to scan it onto your pc and send it to me. I would be VERY thankful !!
I've almost given up so this is my last idea sadly.
Not fun to live in this car-hating-country

Thanks, Johan, Denmark
