According to the CDHA engine catalog, its weight is 144 kg. The CDHA engine number is located at the junction with the gearbox. The most well-known issue of this turbocharged engine is high oil consumption. The manufacturer has released several versions of piston replacements, and replacement often helps. Due to excessive oil consumption, the valves quickly become clogged with carbon deposits and the engine starts to misfire. The timing chain also has a modest lifespan, sometimes stretching up to 150,000 km. Ignition coils, water pump, and fuel injection pump are also considered weak points of this unit.
