What are my rights? E46 bought

Hello everyone, I urgently need your support: On 10.05 I bought a 3 BMW – 323i – 1 HD, 110tsd run – EZ: 06/1999 – Garagenfahrzeug & Chescheheftgepflegt – TÜV&AU New On 11.05 the “first” ride: 290km overpass into the Ruhr area. The following problems occurred now (which did not occur during the test drive!) 1) At a certain accelerator position it whistles out of the engine room 2) during the ride the MKL went on .. was after that 1 week, lights up since yesterday again 3 ) when getting out squeaks and snorts everywhere at the car 4) Splash protection plate for brakes at the front left, rattles abnormally loud and is very unpleasant to me, all people turn around already 🙁 5) lt. Workshop: crossbars no longer available 6) Underbody full of rust (lt dealer is the underbody completely rust-free, otherwise we would not have bought the car at all) 7) lt. Workshop: Brakes Front are due now 8) All 4 shock absorbers must be renewed, 1 shock absorber already oils, the 2 rear are completely rusty 9) when shaking on the rear wheel squeaks again the complete car 10) lt. workshop rear axle no longer ok, was painted black (?) possibly also because of rust What should I do? The dealer is 290km away! Has written in the contract: 1 year warranty on engine and transmission Should I drive to a BMW workshop again tomorrow? Can I drive by car at all 290km? MKL lights up now What are my rights with the dealer? Is this now simply m a bad luck? Can you return the car? It cost me 4350€ + transfer and registration costs (130€) PS: Car passed the Tüv on 10.05, without defects
