Hole in the engine after just under 80 000 km

Hello, I bought a V60 Momentum (T3 engine, manual gearbox) at the end of 2011. So far I was very satisfied with it. About a week and a half ago the gas suddenly stopped reacting, but after several start-ups it went again. Finally I drove with the last force under the supervision of the ADAC to the nearby home workshop (Volvo dealer). There is the car since then. Suspicion of the ADAC technician was a defective petrol pump. The Volvo-Werkstat t could not limit any definitive cause of error, but with very high probability tapped on the conveyor pump. This was also exchanged. On the test drive carried out by the workshop apparently strange sounds were heard suddenly before it caused a powerful blow. Result: Of something the engine was hit in two places, so that the engine has holes in two places with a diameter of about 5-6 cm. Gottlob nobody happened anything – I want to e don’t imagine what would have happened if the bonnet had been open. The warranty has definitely expired, so I hope for Volvo’s coolness now. A swap engine would probably not make sense anymore economically (as of yesterday the vehicle is worth about 10000 €. Schwacke). Did anyone of you have similar experiences or can someone give me tips on how to proceed best?
