What are the main problems of diesel Prado?

What are the main faults of Desai Prado that the landlord is concerned about? The following is my personal opinion:

Prado's faults mainly include loud noise, excessive vibration, high maintenance cost and bad exhaust gas. The filter of diesel engine is easily blocked and needs to be replaced in time. Especially, the high-pressure pump and injector of high-pressure rail diesel engine are more prone to failure, because those impurities and water can easily damage these two parts. Under normal circumstances, it is necessary to clean the throttle and EGR valve when driving about 70 thousand kilometers on urban roads. If the mileage reaches 6.5438+10,000 kilometers, it is necessary to remove all the components and clean them, or directly replace the EGR valve. If you often drive on the expressway, you should clean it every 65,438+10,000 kilometers.
