Hi, interesting views of someone who needs to know. But some of them were already clear before. Quotation: Thomas Schuster, testing engineer of the expert organization KÜS, says about the causes of the increasing engine damage: “Increasing cost pressure at manufacturers and more and more electronics obviously lead to a reduction in long-term quality. Downsizing and the striving for ever higher efficiency, i.e. reduction of the cylinder capacity and the number of cylinders, coupled with increased Einsa tz of turbochargers, have a high probability effect on the service life of the engines.”
