BMW E36 Rost am Dom

Hello together, I had recently posted in the BMW E36 saves, where it is mainly about the rust at the dome of my BMW e36. Since this topic is not only a special BMW problem, I would also like to know the opinion and the experiences of other motor-talklers. The question is whether one would still pass the HU test which is due in August 2018 with the rust at the dome, which is not yet through. I would also have to have at least 1000€ in tires, and longitudinal steering bearings and the rear steering wheel bearings. n to invest brakes, which would certainly be worthwhile with another two years of Tüv. But can one create the HU, if the cathedral is so rusty? Or better off into the press with it?
