The short history of my question: Incidental accident (I was driven up from behind), expert opinion estimated it as economic total damage. Supposedly almost 10,000 € Reparatu costs with a vehicle value of 7,000 €. As the sum comes about, no idea. Externally very little to see, the bumper has got some scratches however completely remained. Otherwise a few decorative strips / apertures have gone to break and a taillight has leaked since then. Everything in my The biggest factor is probably the cross-carrier, which has bent very evenly inwards. More is not included in the report, for worse damages. I will probably fix the damage myself due to the not so high vehicle value. I will do without painting because of the few scratches, the bumper is still good. Now I would probably change the cross-carrier, only with regard to the upcoming TÜV (is probably a safety lack?). I am very well positioned in my craft, also with regard to the tool. In addition, my father was a car master at a young age, so there is still something ”old” know-how available. Alone the welding would be a factor in which it could fail. Therefore, the question before I build the rear more or less apart. Is such a cross-carrier to be welded? Or are they simply bolted? With an image like this looks new to my vehicle. a screw connection?https://www.myparto.com/img/…_9671246280_QQ130U613B_201905201012.jpg I would be grateful for any help! Thank you!
