Hello first of all…. Have a big problem! On the rear axle of the Audi tt quattro is the spring from the suspension and right of the shock absorbers. if you want to remove the spring now you have to unload the scraper below, which connects the damper the brake suspension and so on. So now I had my winch adjusted in a workshop a few months ago, or I even had the counternuts removed from the rear. (had no experience and no experience at that time.) Now they have to take the nut out, also have to open this screw. and then they have put the screw back in again with such an electric impact wrench (looked at it) so now I have installed the counter nut again today because of winter and so, and had to determine the back left this screw had sat very loosely. well nothing at thought, track widening removed, suspension turned up and then I want the screw wied I thought to myself ok, holste am montag ne screw, which is two cm longer and packs on the other side so ne awlbataichernde mother, so long will it still hold where I drove around with it for a few months. but shit was it, after 50m the screw has jumped out. what should it do now??? hope the nothing has been broken. can you take a long time to make it. re screw take and make a nut on the other side? space is enough.if then also both sides, not that of the tüv meckert. must the workshop stick for it? because such a new suspension is certainly not cheap! please help mfg nax
