When I changed my bike on my VW-Jetta the jack slipped and caused a decent dent on the left threshold, which unfortunately can also be seen from the outside through the slightly high pressed sheet metal The opinion of my neighbour (Car-Mechanic): It is absolutely necessary to have the car repaired, because this way the next TÜV can not get through. The assessment of my bodywork workshop (where I was already a customer because of a small dent): It is absolutely necessary to have it repaired. However, the TÜV insists on it. Otherwise it refuses the plaque. Estimate: 800 – 1200 €) The assessment of my VW contract workshop: repair because of the TÜV absolutely not necessary. The dent is not contested from there. It is only important to repair the damaged underbody protection at the place, so that no rust infestation arises. Repair, if desired for optical reasons, comes to approx. 3000 €. The evaluation of a TÜV engineer, who is kindly the No reason for the TÜV to object or even refuse the badge. Can be repaired because of the optics, however, does not have to be because of the TÜV. And what do I do now?: I have covered the damaged spot on the threshold with NIGRIN long-term underbody protection (black bitumen) thickly. Now I wait how the TÜV will react on my next official visit in May next year. If the damage is not objected, the matter is settled. If it does, I will have it repaired then – and only then. Now, as a precaution or only for aesthetic reasons, spend 1000 euros or even more, I think it is unnecessary. Does any of you have any experience in this regard?
