Motor damage Forester SH

Good day I’ve been the owner of a Forester 2.0 D for 6 weeks. Motor damage! Suspected of crankshaft breakage. I applied for a certificate at Subaru Germany. Promptly came a cancellation because the car would be too old. The car has only 143000 km down and that can’t be the one that is already scrap. Now my question. Where do I get an replacement engine and you have a tip as to my right to Kulanz come could? I’d like to continue driving this great car
