Since yesterday something clapped on the back right side of the car. Sounded like a tool, which lurked somewhere in the storage compartment sideways in the trunk. No big thing so. Since I have to drive 2 blags with it through the area, I then carefully drove to A.T.U. (forgiven me) and had a chassis check done. When the car had been so far up that the wheels had been fully springed, I immediately saw that the piston rod of the shock absorber at the back right away The mechanic looked at it and explained to me that the pole at the top of the cathedral (or wherever) would always hit at road unevenness and you should change everything. Springs, dampers… at the front and at the back, because it would make no sense to install only a single new damper with the old spring in the old chassis. Okay… A.T.U. ….. one hears like this. some things. Costs would be everything with installation 995,- €. In the pre-Christmas time certainly very unpleasant. Friends told me it would be enough to install on the axle completely new dampers. One could even take standard dampers, because the lowering would be significantly influenced by the spring length. I have no idea what this is for a chassis. What no TÜV examiner noticed or criticized yet… but today the mechanic told me…. the parts are not registered in the papers. Ha Is it necessary to see how I can get it right again. Question… Do normal dampers also go? Is changing the springs really useful? Can someone recommend a suspension or perhaps advise me from another? Vehicle data is in the signature. At D&W there seems to be nothing for such old vehicles. Ebay already offers some more articles. I tend to have 4 new dampers and the existing green springs, of course not from A.T.U. until the snow is gone, I will still have to ride the Quattro. Thank you
