TÜV forced me to leave the original part one day! Help!

Hello everyone, I just came from the TÜV with a Polo 6n 1.4 Color Concept. No defects, but I had to have my feathers registered! They are the original springs ex factory! The Color Concept series has fitted springs of the company “Eibach” as standard. I also told the examiner several times, but he was 100% sure and did not want to give me a badge if I did not have them entered. He said that he would recognize it by any color codes (or so) on the feathers that it I can’t be dealing with original springs. Then I said that he has come over the TÜV for the last time and that you can also see that the springs have been in there for a few years (he also admitted that it is so). But he didn’t use everything and I had to pay for the accommodation. That can’t be! I’m pissed off!! What can I do? I posted once in the forum “Security” because it is a general topic. Otherwise please postpone. Rice
