One or two years: During the warranty period, the car is in its peak period in the first two years, basically without any problems. At least within two years, most of the cars have to replace the battery. The golf uses a maintenance-free battery. That is, starting from the electrolyte filling into the battery, the battery life begins to count down, usually for two years. Although there is an "observation window" on the battery, you can continue to use it as long as it is green, but there are those who look very "green" but do not say hello to give you a "car park", but do not worry too much, generally the battery The failure occurs when you start after parking and will not give you a direct throw in the middle of the road.
Aluminum Die Casting Engine Cylinder is a metal forming process in which molten aluminum metal is put under pressure and injected into a die. Aluminum Die Casting Engine Cylinder are lightweight alloys that have good corrosion resistance, mechanical properties, high thermal and electrical conductivity and strength at high temperatures. Aluminum alloys possess high dimensional stability for complex shapes and thin walls.
Aluminum Die Casting Engine Cylinder is efficient and economical and offers a wide range of durable shapes and components. Little or no machining is required after a part is die cast, because the process provides very close tolerances for even complex shapes. Aluminum die castings can also be easily plated or finished. Aluminum die castings are dimensionally stable and heat resistant.

Failure performance is that although the whole car has electricity (light, sound, instrument), but can not start the engine, the starter can not turn at the moment of ignition, then all warning lights on the instrument panel mad flash! Don't worry too much. It's because of current instability. They are not bad yet. You have no other way to use the battery of other vehicles to “hook†the car directly to the repair shop for a new one.
In addition, the two-year compulsory brake fluid replacement period. Brake fluid (also called brake oil) is a very easy to absorb oil. If there is moisture entering the oil circuit system, the high temperature generated during braking will vaporize this part of water. When you step on the brake, it will only compress. This part of the air, while the brake pads can not rub with the disc accurately and forcefully.
Two or three years: Replace brake pads and fuel pump. Those who like to step on a lot of oil and then slam on the brakes at the critical moment, the wear of the brake pads must be more severe and the life span is shorter. The common name is "brake disc/brake pad". The brake pads are used more on bicycle tricycles. The brake system is one of the most important parts of a car and is a "safety item." If the engine fails, you can't walk, but if the brake fails, you can be in trouble. You must always check it carefully. Usually in the use of pay attention to the wear of the four front and rear brake discs, whether the surface is smooth, if you find a groove in the brake disc, immediately repair and replacement, brake disc certainly failed, brake disc light To "disc" is to polish it, but also to replace it.
Three or four years: When the car runs up, it may find that it is not as smooth as a new car. If this happens, it is time to check the shock absorber of the car. If the spring of the shock absorber is no longer flexible, it will shake violently at high speeds, and it will be particularly dangerous on rainy days. My understanding is that shock absorbers and springs are two different things. In the suspension system of the vehicle, the main supportive functions of the vehicle are the spring and the leaf spring, and the shock absorber is actually a “damping structure†that absorbs or suppresses the vibration or impact force and is filled with oil. Piston barrel.
To put it plainly, if there were only springs and the shock absorbers were broken, the performance of the breakdown was very typical. It was not a flutter at high speeds, but a "flicker." A little uneven place. The body was just like a boat with bumpy water. All of a sudden, nodded, completely no past calm. If, in turn, the shock absorber is not broken and the spring is broken, the weight on that side of the body will fall directly on that side of the shock absorber, compressing it directly to the head, and that movement can be disastrous, like riding on a stone on.
In fact, it is very simple to check whether the shock absorber is ineffective. Press the four corners of the car body by hand. If the body does not shake back more than once or twice, it will be normal. If it is flexible, it will be bad.
Four or five years: In the case of general family cars, notice whether the timing belt should be replaced. If it is not replaced in time, the car suddenly breaks when it travels halfway, and the maintenance cost to be paid back is relatively high. The main parameter of the timing belt replacement is the mileage (Gallery Forum) instead of the time. It is advisable to replace it slightly within the prescribed mileage.
Five years later: Many people change cars at this time. After all, after five years of racing, the problems will be more. I am not an expert. It is not easy to explain these issues here. If you have a car for more than five years and you want to know more about the maintenance information, you may wish to ask someone in person.
