In the early years of production, the lobes of the camshaft quickly wore out in gasoline engines. The timing chain between the camshafts often stretches in 16-valve engines. The first-generation turbocharger often fails due to clogging of its filter. The 8-valve engines of the second generation are more reliable and practically have no weak points. Diesel engines here also have typical problems with the soot filter and EGR.
