You forgot the dots.
TÜV.
If the keyboard doesn't have the appropriate key, the correct form is "TUEV". That is a pretty good approximation of how it is pronounced, too. The sound of the the "ü" (as well as the "ö" and the "ä") doesn't exist in english. It has to be learned, and after nearly 30 years here, I still don't consistently hear the difference to "u", "o" and "a".
Other than that, and the ramdon gender of articles, german is a pretty cool language. Very precise.
But yes, the TÜV, DEKRA, GTÜ and KÜS are the businesses that carry out the bi-annual inspection, and the ones the have the kittens.
The TÜV is the most common in what was formerly West Germany, and having the inspection done is commonly referred to, approximately, as "getting the TÜV".
