Hey guys!
I'm from Switzerland and the new owner of a Golf 5 GTI with more than 190k miles :) after seeing your diy, I decided to participate and register :)
UPDATE (07/11/2017): It has been 3 weeks and I still cannot take part to the forum. I can't reply posts since apparently my account has not been activated by a mod and is limited to two posts initially. Could any mod do it please?
