The AGU engine assembly weighs 150 kg. The AGU engine number is located at the junction of the block and the gearbox. The turbocharger can quickly fail when the catalyst is clogged. The VKG system causes many problems, especially its frequently cracking pipes. The engine speed constantly fluctuates due to air suction in the intake manifold. The oil pump and the timing chain tensioner have a very limited lifespan here. Unstable engine operation is often caused by failures of the DMRV or DTOS.
