The sensitive piezo injectors quickly fail due to poor fuel quality. Diesel engines manufactured before 2009 suffered from a problem with the oil pump hexagon. Oil often leaks from under the plastic valve cover in the engine. According to the factory schedule, the timing belt lasts for 180,000 km, and if a valve breaks, it causes damage. The diesel particulate filter and EGR valve are a source of many problems at high mileage.
