The weight of the BWK engine according to the catalog is 130 kg. The BWK engine number is located at the junction of the block and the gearbox. The intake valves on the left side clog up with carbon deposits, causing a decrease in compression. Additionally, due to detonation, the pistons simply burn out and it is better to replace them with forged ones. The oil control rings often become clogged around 100,000 km, resulting in an increase in oil consumption. The timing chain has a relatively short lifespan and often requires replacement at 100,000 km. The control valve and wastegate of the turbocharger regularly fail. Owners constantly complain about coolant leaks, usually around the intercooler area. Another unpleasant feature is periodic vibrations when starting cold.
