Over-smuggling of the air-saving doors can lead to a decrease in engine power, a lack of speed, which can lead to a breakdown of the fire, and serious problems of consistency such as engine failure lights。
Carbon accumulation is not a problem that can be solved overnight, it is a chronic disease of the engine, which, if over-carbonized, can lead to accelerated impotence, slower speed response, higher fuel consumption, and low tank pressure and unstable engine speed at low speed. Regular carbon cleansing can restore the mist of the oil-jet mouths, maintain the flow of oil, restore engine power, remove engine cold start difficulties and slow speed failures, improve fuel economy and extend the life of spark plugs, oxygen sensors, tri-channels and engines。

The long running time of the car increases the amount of carbon accumulated in the vents, gas doors and combustion rooms, as well as the adsorption of fuel in the cars, the release of fuel in the hot cars, the lack of ease in the cars and the high consumption of fuel in the hot cars, leading to a deterioration of engine performance, as well as poor performance, such as glittering, poor acceleration, increased fuel consumption and exhaust gas. So cleaning the carbon accumulated in the combustion room can reduce the above-mentioned failures。

Most of the audi car types included in this book are new and some new high-end models in the country in recent years, and every car maintenance case recorded is classic, rich, and provides the right diagnostic thinking and solutions, with strong maintenance guidance. The aim is to ensure that these maintenance cases are applied directly to day-to-day work and effectively address the problems that arise. The book is classified according to the four main systems of engine, transmission, chassis and body, and each system is classified according to different vehicle types, with a strong sense of reason and easy to read on demand。
The book includes, inter alia, the analysis of cases of failure maintenance of various vehicle types, such as odi a4l, a6l, a8l, q5, q7. The book is suitable for use by a wide range of audi maintenance front-line technicians and may also be used in vocational colleges and audi training institutions。
