Repair of a German engine in Russia

I'm assembling the OM 442 engine. The engine is from the Setra 315 bus. The bus was bought in Germany in 2014, the mileage across Russia is 1,000,000 kilometers. It is not known how long the bus traveled in Germany before. I think the total mileage of this engine is 3 million kilometers.
