TÜV and chassis number – bad experience with TÜV !!!

Hello, a friend of mine and I myself have had very bad experiences with the TÜV regarding chassis number in the last two months, we both did not get the badge for our classic cars, my buddy, because the number was not hit in the car but only on a sheet metal plate. With my old car, the gentleman in the coat did not find the chassis number at all, a look into the operating instructions helped him then. But on the small riveted sign, the last digit is strangely missing, which was taken by the friendly one as an opportunity to deny me the badge, he said that I was going to have trouble with a police check. I have never seen the police check the chassis number during a check. Besides, I received the badge from the same examiner already in 2011 and 2009, he apparently didn’t care about the number. Then I asked, If you want me to do that, the answer is: first use the cardboard letter to determine whether the last digit is there or not and then come over again. But that’s exactly what I won’t do! After exactly 35 years of vehicle owners, mostly of several at the same time, and estimated 25 main investigations exclusively at the TÜV, I will go to the Dekra or the GTÜ in the future.
