Recently, many automakers have started to equip their cars with turbocharged engines. Such motors, in comparison with the usual atmospheric ones, are distinguished by greater power and efficiency. In addition, they better meet modern environmental standards. But at the same time, many motorists, especially those who prefer to buy used cars, still opt for cars with atmospheric powertrains. Why is this happening? Are today's turbo engines so unreliable?
With the advent of the Euro-5 environmental standard, more and more cars with turbocharged power units began to appear on the world market. Despite their growing popularity, it has become known over time that not all of these engines are reliable. In this case, most of the problems arise on a mileage of more than 200,000 km. Therefore, experts from the Japanese publication "Best cars" have identified motors, cars with which are not recommended to be purchased on the secondary market. Among the most common in this list are engines such as the N45 from BMW, TSI and TFSI series 1, 4, installed on cars of the brands AUDI and Volkswagen, as well as 1.0 EcoBoost from Ford. Some other turbine engines were also included in the list, but they are not so popular among Russian motorists.
The engines mentioned above have many serious problems, the solution of many of which requires a significant investment. Such power units often suffer from oil starvation or receive significant defects due to improper distribution of the lubricating fluid. In addition, many of them have proven to be incredibly demanding on fuel quality. And experts consider the main damage to such motors to be the deformation of the valves and the burnout of the pistons. To eliminate such malfunctions, complex and expensive repairs will be required. In some cases, the masters may only advise the owner to replace the power unit.
It should be noted that most often the owners of cars manufactured before 2012 face similar problems. In addition, it is believed that turbocharged engines can withstand up to 300,000 km of run without major repairs. True, this is possible only in the case of high-quality and timely service.
Therefore, those who want to buy a used car with a turbo engine should not buy too old vehicles or cars with impressive mileage. And before buying, you should definitely diagnose the engine from a reliable specialist.
