TÜV: What are the consequences if defects cannot be repaired within the time limit?

Hello dear A2-fans! I got into a kind of mess at the moment: We stay every year 3-4 months for family/social reasons in Finland. Now it turned out that a greeting customer service and a main inspection of the TÜV was carried out in time before the departure. To my surprise, the TÜV found a lack that had to be fixed only in order to get a badge on the license plate again for the next two years. Problem: cross handlebars, in front correctly ts, restricted by rust damage and no longer portable. The timely and necessary procurement of this transverse handlebar is currently not possible. Workshop: Could take 1-3 weeks according to experience! Fixed/fixed departure of our ferry to Finland 13.5.2018, embarkation 12.5.2018 from 22.00 h. This only to history. What does this have for me for consequences, if I would only be able to show the repaired car to the TÜV after 4 months. the/exception permits for verifiable/understood circumstances? Of course, I am still looking for target-oriented alternatives in terms of the timely procurement of crossbars. Please hold all the thumbs that you have so that we can reach the ride in time! Thank you, still much pleasure on May 1st all real A2 fans and their friends of course too! B l a c k y (alias Finn-Frank)
