406 Coupé 3.0 V6 24V problems

Servus Löwenfreunde, I have a 1997 406 Coupé 3.0 V6 24V (Phase I). Was at the TÜV….he had a lot to complain about (significant defects…. :wall_banging: Holding tape tank – there is no longer to buy from Peugeot…Do you know what you can do there, except to look for a used one and to build it? Drive shaft bearing – buffers knocked out. Can you change it? Does this part fit?https://www.ebay.de/…/282826767757 At the rear axle left “klimperts” it when driving over from Sideways…and the brake on the rear left has a bad effect. Also the handbrake. Should I install new brake sheaths and pads or keep the old ones? I got a repair kit for the caliper, but I’m not sure if it’s broken. I think the bellows of the drive shaft are broken on the left. Is there a special trick except to get a cuff spreader? Oh yes…he has installed the BREMBO system…if that’s any And in the end: He didn’t pass the AU. Too much Co2… in idle and at 2.2k to 3.K rpm. The engine starts always and reliably, however, smells of gasoline a little bit until I go off and a maximum of 500m afterwards….then there’s nothing to smell. The examiner said that she pulls FALSE AIR….my workshop says..nix da… power loss…NEVER EVER….bubble with her regularly far stronger and NEWER AUTOS. ALPINA DX3 BiTurbo..ML 350…AUDI TT …etc. What can that be? I know, needle in a haystack…please, help me. I bought it to prepare and drive it as a vintage car. LG Fred. 😛
