Beijing-based Mercedes-Benz Sales Service Co., Ltd. announced recently that it will reduce its maintenance costs. The Mercedes-Benz after-sales service after the price reduction is launched in the form of “Star Emblem Maintenance Menuâ€, which includes basic A maintenance (small insurance), basic B maintenance (great insurance), and fixed-cycle parts replacement and wear parts replacement services, and all service content. The menu price is the “package price†for accessories and working hours, and is applied uniformly across the country.
Mercedes-Benz's after-sales maintenance costs have always been expensive. Today, as car prices are declining, such high maintenance costs have become the focus of complaints. After the introduction of the new standard, the average price of Mercedes-Benz vehicles can be reduced by an average of 20%. It is reported that the price reductions of some models and some of the projects can reach a maximum of 50%. I believe that many owners can break their smiles.
But even so, going back to a 4S shop can cost hundreds of dollars at a time, and it costs thousands of dollars at a time. In fact, it is just a matter of routine maintenance. This money is used in everyday life and may be able to do a lot of things. However, when used in a car, it always makes people feel that they have spent a lot of money to do small things. No way, whether it is the high working hours in the 4S store or the price of accessories that make people stunned, it is determined that the 4S shop has a friendly smile and a delicious free meal, but it is by no means there We should always visit the place where an ordinary car owner should visit. How to save money on vehicle maintenance, we have to find ways for our owners.
How to save the most money?
How can you bypass the lion's opening in the 4S shop but at the same time ensure the quality of car care? As owners, not only have to be bold and have to worry about.
Take advantage of free testing opportunities
Today's car manufacturers pay more and more attention to after-sales service, which benefits the owner as they often enjoy free testing activities. Many of these free testing activities appear to be simple and appear to the owner as having no substantive content. In fact, these free testing activities are very beneficial. Car owners can use these free testing activities to conduct a comprehensive physical examination of the car, discover potential problems in a timely manner, and eliminate these hidden troubles, eliminating the need for high maintenance costs in the future. And some of the 4S shop's free testing activities also include free maintenance content, these services are real benefits, because they are usually charged.
Accessories from the purchase price cheap
The realization of the majority of people have misunderstood the auto parts, that only 4S shop accessories are genuine parts. The parts used in the 4S shop are directly supplied by the manufacturer. However, the 4S shop is not the only distribution channel for genuine parts. For example, some dealers will purchase imported car accessories from other channels. The original factory parts of domestic cars can also be purchased through accessories manufacturers and other channels. Therefore, some 4S stores occasionally go to the accessories market to purchase their own accessories when they encounter tight fittings. The same is true factory accessories, 4S shop and the market price as much as 30% to 100% of the difference, it is not difficult to understand.
What makes people cry and laugh is that 4S stores often exaggerate the gap in the quality of genuine parts and accessories purchased from other sources in order to make high-priced accessories appear to be based on price. It is true that the quality of the factory parts is reassuring, but the accessories purchased through channels other than the 4S shop are not equivalent to inferior parts. The so-called factory parts are auto parts manufacturers authorized by their suppliers. In addition to the authorized factory parts for car manufacturers, accessory suppliers will also produce common accessories of the same type, which is often referred to as the vice factory accessories. However, the gap between the quality of the factory parts and the accessories of the vice factory produced by the same manufacturer is actually very small, and there is no gap at all.
Whether it is through physical stores or online e-commerce, as the owner or should have the most basic ability to identify. What we want to buy is quality and can replace the original qualified parts instead of fakes. There is a fundamental difference. There are several ways to identify whether it is fake or not:
First, look at the packaging. Good accessories are exquisitely packaged, and the printing specification should be marked with the title of the goods, specifications and models, units, registered trademarks, names of the factories, site and telephone number.
Second, look at the surface of the accessories. Qualified parts are printed or cast on the surface in clear and regular form, both delicate and bright. If you find that parts have metal corrosion, cracked rubber parts, or rough metal processing traces, the possibility of encountering a fake product is very high.
Third, look at the paint. Some unscrupulous traders have sold used parts and refurbished new parts to sell them. Rough paint will expose the identity of these refurbished parts.
Fourth, see the assembly process. A part made up of many parts is pressed and glued, or riveted. It is a test process. If the assembly is not precise enough, it is probably a knockoff product.
In fact, do not be intimidated by the identification methods of these fakes, as long as it is through regular sales channels, and do not blindly covet for cheap, you should be able to buy reliable products. We need to pay attention to the specific model of the original parts, because different models or even different batches of models may use different parts, therefore, before buying, we must determine that the parts meet the needs of replacement. In addition, the expert's suggestion is that for some key components, because it may be related to the safety of driving, so try to purchase through 4S stores and other reliable channels.
Reasonably determine the maintenance cycle
The vehicle maintenance cycle is the interval or time between car maintenance. High maintenance frequency is not a bad thing and can more effectively protect the performance of the vehicle. Therefore, scientifically determining the interval between maintenance operations of various types can not only keep the car constantly in good technical condition, but also enable you to save maintenance costs and repairs. cost.
When deciding on the automobile maintenance cycle, the maintenance cycle recommended by the automobile manufacturer should be consulted. Combined with the automobile's own technical conditions and actual conditions of use, the maintenance cycle should be properly adjusted. A new car with good general automotive technology conditions can be properly extended for use under good operating conditions. However, if the condition of the automotive technology is poor or the operating conditions are poor, the maintenance cycle should be appropriately shortened.
Smart purchase of accessories can also extend the vehicle maintenance interval. Many consumables, including oil, fuel filters, and oil filters, are actually equipped with long-lasting parts. These parts can have longer use efficiency than ordinary parts, which means it has a longer time. Replacement cycle. Although the price of these spare parts may be slightly higher than ordinary spare parts, on average it is cost-effective and peace of mind.
A careful inspection of the store
Buying spare parts, you have to find a master to help replace the maintenance. How can you find a reassuring car repair shop?
First of all, look at the repair factory belongs to several types of maintenance factory, China's Ministry of Transportation's maintenance qualifications for auto repair factory is divided into three categories, a type of repair factory is an enterprise that can carry out major engine repairs, the production site and the scale of investment is large, the quality of personnel The requirements are relatively high, and the charging standard is higher than that of the second type of plant; the second type of maintenance plant cannot perform engine overhaul, the production site and investment scale is relatively small, and the charging standard is lower than that of a type of plant; the three types of maintenance plants are special maintenance plants. , Such as automotive air conditioning, audio, tires, car cleaning and more. When a car engine is overhauled, it must be repaired by a type of repair shop.
Secondly, to see if the license of the plant is complete, it mainly refers to the technical qualification certificate issued by the industry management department and the business license issued by the business administration department.
Third, see if the plant implements public service commitments, open working hours charging standards, open complaints calls, open production, work processes, etc., the general formal repair shop will also post technical staff photos and resumes, public parts prices, vehicle maintenance After the warranty period and so on.
Fourth, look at whether the plant's management system is sound and whether there are various normative criteria that the industry management department requires to implement. You can also go to the workshop to see if the staff uniform dress code and job number, whether the auto parts are scattered on the ground, etc., because the formal repair shop must strictly implement the industry management department "tools do not fall, parts do not fall, oil does not land" The requirements.
There is also an ideal way to find a rider club around you. There are many mainstream models that now have owners' clubs. Most of these clubs have maintenance facilities that serve a single model. These maintenance plants, although not necessarily highly qualified, have the heavy security of owners' clubs, so the quality of maintenance is relatively reliable. In addition, they are always engaged in the maintenance of a single model. The masters naturally also make perfect practice.
To save money by raising a new generation!
Instead of spending a lot of money on repairs when it fails, it's better to spend more time thinking about doing maintenance. After all, like people, all the problems are not formed in one day.
Chassis maintenance
Chassis care is easily overlooked, but the importance of chassis maintenance in winter or wet weather is very important. Rain and snow often have silt and water stains on the chassis. There are even many roads in the north that use salt to remove ice and snow from the road. They are not only difficult to wash but also have strong corrosion to the vehicle chassis. Sex, long time, the chassis is easily eroded and rusted. Similarly, in the southern coastal areas, corrosion of the chassis is also very easy to emerge. Therefore, the first step in the maintenance of the chassis is to regularly keep the chassis of the vehicle clean.
Regular cleaning
High pressure water jets can flush out the original sediment on the chassis. If there is too much mud on the chassis, wash it with degreasing detergent to expose the chassis to its original character. In the rain and snow season, we can additionally carry out anti-rust treatment on the chassis. It should be noted that after washing, be sure to wait until the water on the plate is completely dry before carrying out anti-rust care. When performing care, it is important to maintain a uniform spray of anti-rust agent to form a layer of durable anti-rust coating. After the completion of all the natural air drying 5-10 minutes, the chassis rust treatment is completed. Do a chassis rust treatment, anti-rust effect can be maintained for three months. Basically, it only needs to be done twice a year before winter and the rainy season. After a professional chassis care, it does not mean that it is completely foolproof. There is a misunderstanding that people often add some detergents when washing cars. At this time, please be careful not to use alkaline cleaners to wash the body and chassis, otherwise it will affect Anti-rust effect and shorten anti-rust time.
Chassis armor
In order to keep the chassis rust-proof for a long time, the most fashionable of the time is of course chassis molding, which is often referred to as chassis armor. At present, in the selection of materials, a large number of professional automotive beauty shops have made major breakthroughs, and rubber sealants have been used to replace materials that originally used paint, asphalt, etc. as their main substrates. This kind of product also has high tightness, waterproof, rust-proof, non-toxic and environmental protection. Chassis armor can shock absorption and improve driving comfort. A large part of car noise comes from the noise of road noise and sand hammer. The high elasticity of chassis armor can effectively absorb and reduce these noises. At the same time, it also reduces the noise caused by the vibration of chassis steel plate, thereby achieving the purpose of noise reduction. The most important, this kind of flexible material can greatly reduce the road scratches on the chassis damage.
Chassis armor is not a small project, it takes a few hours before and after. First of all, the construction crew must lift the vehicle with a lift to remove the wheels, fenders, and brake pads; then lift the vehicle up to a person's height and thoroughly clean the bottom of the vehicle; then blow it dry. The sprayed parts are wrapped; finally, the chassis armored material is repeatedly sprayed to a certain thickness, and after the watch is dry, the tires are mounted and the wheel alignment is completed, so that the whole process of chassis armoring can be truly completed. Before the armor material is completely dry, the chassis part of the vehicle needs to be kept dry, otherwise it will affect the armor effect.
Scheduled maintenance
As one of the important parts of the chassis, the suspension plays an important role in carrying the weight and direction of the car. The regular inspection and replacement of rubber cups and hydraulic components at the joints of the suspension section and the firmness of the fixing screws are very important and are also the prerequisite for safe driving. The maintenance of the vehicle is "three points of cultivation, seven points of support." Do not use all the generous replacement, care about is a bit of careful care.
Chassis components are likely to cause deterioration of lubricating oil during wading, especially when it comes to systems such as steering and transmission. Maintenance manuals of some models also require grease to be added to chassis components after wading. Note and other maintenance work. At the same time, during the road test, listen carefully to whether there is an abnormal sound in the chassis, or carefully inspect the chassis, and perform rust prevention and lubrication in time.
Regular four-wheel alignment is also an essential process for caring for the chassis. The four wheels on the car seem to stand upright on the ground. It is not true. If you use the instrument to measure, you will find that they are all deflected by an angle in the three planes of X, Y, Z, but the value is very small. Not visible to the naked eye. Do not underestimate these three small deflection angles, they affect the car's driving and steering performance. If an accident occurs, or if it takes too long to change the four-wheel positioning parameters due to wear, the maneuverability will be greatly reduced. Therefore, if you feel strange while grasping the steering wheel, you should go to a professional repair shop to conduct the inspection and make corresponding adjustments. Not much, but it ensures safe driving and maintains optimal vehicle handling.
Interior maintenance
Relative to the engine and chassis, etc., perhaps the interior quality does not directly affect the life and performance of the vehicle. However, with the increase in the age of the car, can you have a pleasant driving experience in the face of an interior that is not well maintained and dirty? Therefore, if you want to earnestly drive your car for 10 years and 8 years, the maintenance of the interior should not be less.
Clean seats should be gentle
Mid- to high-end cars use leather seats and leather door trims, and many drivers have converted their own leather seats to provide comfort, luxury, and long life. The genuine leather is a natural thing, so it cannot be neglected when it comes to maintenance. The best leather do not use protective agents, this kind of material will make leather addictive, must be used often, otherwise the leather will be dull, no vitality. And the key is that, in addition to brightening, protective agents have no benefit to the dermis. Chemical cleaning agent can not just spray up, should use strong alkaline cleaning agent, like soapy water can be like, wash and then wipe dry with a cotton towel.
For general fleece seats, the cleaning method is to open the door first, clean the dust with a duster, and use a vacuum cleaner to suck out the dust. When using detergents, try to allow the foam to spread on the surface of the seat so that the dirt attached to it floats. When the foam gradually decreases, use a brush again. Do not use too much force when brushing. Simply brush the brush gently over the surface. This will be enough to brush off dirt that is invisible to the eye. Finally, dry the foam with a wrung wet towel. After cleaning, open the door to allow the car to be well ventilated so that the seat can dry as quickly as possible.
Seals will not seep due to maintenance
There are seals on the edges of doors, windows, and sunroofs. These inconspicuous aprons are often overlooked by car owners who care for cars in the summer. As we all know, the seal ring is because it has a glial characteristics to play a sealing role. If the seal is exposed to the sun for a long time, aging, loss of elasticity, and even cracking are likely to occur, and the sealing performance will be greatly reduced. This will not only affect the sound insulation effect of the vehicle, but also cause leakage, seepage, etc. in serious cases.
Auto-cosmetic experts pointed out that to maintain good performance of the seals, car owners must start from daily maintenance. The owner can clean the seal once every two quarters. Specifically, wipe the dust on the slide rails and grooves with a clean damp sponge, then wipe it again with a dry sponge to keep the seal ring clean. These operations are quite simple and basically do not require a dedicated car wash shop. If you use a high-pressure water gun during car washing, remember not to spray the water directly on the seal ring, otherwise it is easy to cause deformation of the seal ring under the impact of the high-pressure water column. Over time, the seal performance of the seal ring will be affected, and the car will be more Easy to seep. At the same time, the owner must pay attention to where the car is parked. When it is necessary to park outdoors for a long time, the vehicle should avoid direct exposure to the sun. If possible, it is best to cover some car-specific reflective clothing to prevent deformation of the seals on the doors and skylights due to heat or turtles. crack. If you can't avoid it, don't do physical cooling by directly splashing the water. A large temperature difference will often change the internal structure of the sealant, causing it to crack. In addition, regular maintenance of the sealant strips on the vehicle with rubber care agents also allows the seal strips to remain resilient over time.
By the same token, long-lasting sunroofs will emit awkward noise because of excessive dust and grit on the slides, and the track is seriously deficient in lubrication. The skylight maintenance work we can complete completely. We only need to open the skylight completely, wipe the dust and stones on the sunroof rail with a clean soft cloth, choose a lubricant that is not sticky and not easy to absorb, lubricate the sunroof's transmission track, and finally close the sunroof completely and open it several times. Wipe excess lubricant with a soft cloth. This simple daily maintenance is completed.
Engine maintenance
Some cars tend to give people a brand new look. They don't open it up. As the most sophisticated part of the car, the engine is also a part that is prone to major problems. We must always wait to serve it well.
High-quality engine oil change on time
Owners are usually willing to spend money on car repairs and modifications, but they do not agree with the choice of oil. In fact, according to statistics, the fault caused by poor lubrication of vehicles accounts for 40% of the total fault. Therefore, the driver of a car should pay full attention to the role of lubricants, ensure reliable lubrication of the engine, reduce wear, reduce failures, extend vehicle service life, and avoid failures. Necessary loss. It is not enough to choose the right oil. The quality of any quality lubricant will change during use. After a certain mileage, performance deteriorates, causing various problems to the engine. In order to avoid the occurrence of faults, the oil should be regularly changed in combination with the conditions of use, and the amount of oil should be moderate. Generally speaking, it should be within the upper limit of the oil gauge. When replacing the oil, do not forget to replace the oil filter. If the filter is seriously contaminated and causes blockage, when the oil cannot pass through the filter element, it will burst the filter element or open the safety valve, pass through the bypass valve, and still bring dirt. Lubricated parts will accelerate engine wear and increase internal pollution.
Intake system often clean
The air intake system of the engine is mainly composed of an air filter and an air intake. According to different conditions of use, it is necessary to regularly clean the air filter element by blowing high pressure air from the inside out and blowing the dust out of the filter element. Since the air filter is paper, it should be noted that the air pressure should not be too high when blowing so as not to damage the filter element. The air filter must be replaced after 3 cleanings. The cleaning cycle depends on the working environment of the engine. Driving the dusty area for a long time is to shorten the cycle of cleaning the filter element. At the same time, regular cleaning of the air intake can also ensure the smooth flow of air. The intake system is very important for the normal operation of the engine. If the air intake system is dirty, it will result in a decrease in the charging efficiency, which will reduce the output power of the engine.
Fuel supply system for youth
The maintenance of the fueling system includes the regular replacement of the fuel filter, the cleaning of the carburetor or the fuel nozzle, and the oil supply line. During the combustion of fuel oil through the oil circuit to the combustion chamber, it will inevitably form colloid and carbon deposits. It will deposit in oil passages, carburetors, fuel injectors and combustion chambers, interfere with fuel flow and destroy normal air. The fuel ratio causes poor fuel atomization, causing engine performance problems such as engine vibration, knocking, unstable idling, and poor acceleration. Using fuel system cleaners to clean the fuel system will always keep the engine in top condition.
Cooling system cannot leak
People care about the maintenance of automobile engines. The main concern is the lubrication system, and little attention is paid to the cooling system. In an interview, the reporter found that the most common faults of automobile engines, such as piston pull, knock, leakage inside the cylinder punch, serious noise, deceleration of acceleration, and so on, are due to the abnormal operating temperature and pressure of the automobile engine. , caused by poor cooling system conditions. When one engine is in a good condition in other systems, whether the cooling system can effectively maintain the normal operating temperature of the engine fundamentally determines the working condition of the engine. To make the engine work at the right temperature at all times, what we need to do is to regularly maintain the tank.
Rust and scaling of engine tanks are the most common problems. Rust and scale can limit the flow of coolant in the cooling system, reduce heat dissipation, cause the engine to overheat, and even cause engine damage. Coolant oxidation also forms acidic substances that corrode the metal parts of the tank, resulting in breakage and leakage of the tank. Regular use of water tanks for powerful and efficient cleaning agents to clean water tanks to remove rust and scale from them will not only ensure normal operation of the engine, but also extend the overall life of the tank and engine.
