The weight of the AUQ engine assembly is 150 kg. The AUQ engine number is located at the junction of the block and the gearbox. The main cause of the unstable operation of the engine in constant air suction through the VKG is the numerous cracks in the crankcase ventilation system pipes. The chain tensioner has a low lifespan, which serves as a phase regulator. Coolant leaks from the cooling system manifold and failures of the DTOZH are commonly encountered. Ignition coils with built-in commutators quickly fail.
