TÜV examination with expert report but without registration ?

Hello, dear community. I hope I’m right here. Actually, it’s more about law and law than about safety. The following problem: About 2-3 months ago I changed the chassis at my VW Scirocco. From series to a Bilstein B12 Pro kit. So springs and dampers new. I then had the whole thing “take off” at the TÜV Süd, which nowadays only means that an “inconvenient opinion” is created. Since my car is now not in my place of residence Stuttgart, but in my own In the home town of Celle (with my mother) I was not able to go to the registration office with the certificate issued, since according to TÜV Prüfer only the competent registration office takes place. Say: I would have to go to the ZS in Celle. Since I did not want to take a total distance of 1100km for this purpose, I sent my vehicle registration certificate and the corresponding certificate to my parents and discussed with you that they should have the registration carried out on my behalf. n. Since the car is still financed, the vehicle letter, which is additionally required, lies with the VW Bank. My mother then also requested it. But the letter then went directly to the ZS and my mother received only one letter, which she thought was advertising. In this an indication that the letter is demanded back after 3 weeks. So these 3 weeks have passed and the vehicle letter went back unchanged to the sch**** VW Bank. The whole action was then sent to me by V Olkswagen also kindly charged with 15€ postage fees. FREQUEST! Anyway, my HU is due and the conversion is still not registered. Can I get to the TÜV examiner at all (with vehicle registration + expert report), or will he reject me directly? I can’t just shut down my car because of this complication. I need it for the work journey every day. What about her???
