Clean doors and TÜV…

Moin, in just under two weeks I will have my polo clean (so the rear, doors and MH extension). Now I have a question excellent of the TÜV acceptance. I have heard the most surprising things, what you have to do to get doors without handles & locks over the TÜV. For example, install rope train and emergency exit stickers and such stories… Would be nice if you could tell me exactly what I have to do to get my cart over the TÜV… And another thing: M what price do I have to count (are other things that have to be registered) the following must be registered (unless ABE, it doesn’t know exactly what is now entry-free): – Front apron – Rear apron – Side skirt – Suspension – Sports seats incl. Schrothguts – Back bench – Doors clean – MH extension – Rear clean Thanks for your help Stefan
