Hi guys new to this forum thing. Also new to Germany originally from Ireland. So I just want to know what is the procedure with modification. I understand when buying aftermarket parts you can get a TÜV certification with it. And Iv read into something called Dakra. So what I want to know is my car is currently standard I have looked at some parts that come with the cert some dont. The car has tüv will be out soon. If I install the parts and bring the certs with me will it pass. And what about other parts that don’t come with certification. I’m use to Ireland’s system where it’s do what you want and see what you get away with. Any help would be much appreciated. I’m living near brake so even any places to send me to I would greatly appreciate thanks.
