Need Advice-Used car for 5 months and Rear Differential issues
I bought a used X1 2016 from a used car dealer, within 2-3 weeks of buying noticed noise and rattling on motorway related to throttle. Dealer changed all mounts including gearbox/engine and tracking rods and alignment done. That noise did improve a bit but never went fully. Anyways 4 months forward now noise is loud, a garage checked over and they said my rear differential needs to be replaced as there was metal in diff oil so possibly differential bearings gone. Cost is £3194!!!! I do have handler protect warranty but seeing online reviews I dont know what to do. Should I do warranty route? Call dealer? Or just swallow this and pay by myself?? Please any advice would be appreciated I am desperate. Thanks
