The dry weight of the M 48.50 engine according to the catalog is 253 kg. The engine number M48.50 is located at the junction of the block and the oil pan, facing downwards. The main problem with this turbo unit is the formation of scoring in the cylinders. Poor fuel or oil, as well as driving with a cold engine, are often to blame. Leaks of coolant due to burst pipes and expansion tank are not uncommon. With very active use, the hot part of the turbine can crack before reaching 100,000 km. Weak points also include ignition coils, starter, thermostat, and water pump.
