The weight of the B284L engine according to the catalog is 215 kg. The engine number B284L is located at the junction of the block and the gearbox. The most well-known problem of this engine is the low lifespan of the timing chains. Electrical issues often cause trouble, with the ECU and oil pressure sensor being the most common failures. Overheating with gasket failure due to a stuck thermostat is not uncommon. The turbo operates normally, with only the bypass valve or wastegate occasionally failing. Weak points of the power unit include ignition coils and the fuel pump.
