By the most important change of season in the year, people on the move should not forget to take a car to the shop for a full-body examination. According to incomplete statistics, a significant proportion of traffic accidents in beijing are directly or indirectly related to the vehicle's own condition, which is similar to that of the human body. In the change season, a large number of vehicle crashes have been concentrated, as is evident from the recent frequency of traffic accidents in the city。
Car repair and maintenance was reported on 30 april to be the most important change of season in the year, and people on the run must not forget to take a car to the shop for a full-body medical examination. According to incomplete statistics, a significant proportion of traffic accidents in beijing are directly or indirectly related to the vehicle's own condition, which is similar to that of the human body. In the change season, a large number of vehicle crashes have been concentrated, as is evident from the recent frequency of traffic accidents in the city. In case of a pre-emptive situation, the current version of the plan will lead you to eight major problems in your car and see how the experts will help you to clear up your troubles。
1 engine problem
Problem expression: no fire, no noise, no noise, no glittering, oil
Typical models: shali, maeten, audi a6l, alice
The problem is solved: there are fewer problems with the real engine during the actual use of the vehicle, and the owner of the vehicle is well placed to prevent engine problems through routine maintenance. The expert advised that the oil could be changed if conditions were available, as the viscosity of the oil would vary over time。
In response to the problems that may arise in connection with the engine, the manager, sou bao-sung, after the sale of the east wind's first car, believes that if the engine fails to burn, most of the reason for the failure of the battery to start is the failure of the battery to start up; when the air-saving doors suddenly shut down after start-up are too dirty and are now electronic gas-saving doors, computers can be a reminder of problems; and when the vehicle is shaking, three factors may be responsible, including the age of the foot mat, the cracking of a tank, the poor performance of the oil-jet mouth, and the poor quality of the oil。
In response to some of the car owners ' concerns about the high noise in the car, sou bao indicated that if the noise was felt, it would probably be psychological, as some models were slightly more noised after normal maintenance。
Two gearbox problem
Problem: unsatisfactory, unsettling
Typical vehicle type: shali, swing, shido, odyssey, chang-am suzuki sx4
I don't know
Depending on the type of gearbox, the problems that often arise are different and subject to differential treatment。
After the sale of the cvt, the manager su bao concluded that, in the case of the manual block model, the problem was generally more noise-prone and unstoppable; in the case of automatic blockages, there was a greater risk of jump and frustration, but care was taken to distinguish between whether it was not a real problem or whether the model itself was less effective, for example, as a result of the impact of some old car-type shifts; in the case of cvt transformers, the problem might be oil spills or slips; and now the more advanced double-laying dsg transformers, although they were passing at a good speed, had a high noise problem。
3 chassis problem
Problem manifestations: hanging, running, chewing, shaking in the direction, revolving machines
Typical vehicle type: south east v3, freddy, tianjin, yakoh, flying cvt, koruz
I don't know
There are problems with the chassis, which generally have three aspects, including a brake system, four rounds of positioning and acoustic noise。
After the sale of the east wind's first car, the manager, sou bao-sung, believed that the brake system should be a more critical part of the chassis, and that toyota's recent recall was due to problems with brake blades。
These phenomena, such as run-off, gnawing, and gliding, involve four-wheel positioning issues, including forward positioning and the dynamic balance of tyres。
In order to prevent this malfunction, the owner of the vehicle can avoid the pit-tight road during normal driving, in particular by bypassing the large bumps, and be more careful not to crash into the four-wheeled positioning system by hitting the side of the road。
Four brakes
Problem: brakes are soft, non-functional or non-functional, they sound loud and they shake strongly
Typical vehicle type: junha, coruze, flag cloud, same jump, alice, antelope, carola, fox, flying degrees
I don't know
The soft brakes, commonly known as the inability to be sensitive after stepping down the pedals, are usually a problem which may be smaller than the brakes used in the front drive, or where frequent brakes cause a severe heat decline in the brakes, or where severe brake hooves are worn to cause the brakes to fail, or where the brake oil is too dirty to be replaced. Experts noted that the use of smaller brakes to reduce costs, or the normal quality of brakes, had led to many models being insensitive after some time in use, leading to some tail-backing accidents。
In the case of softer brakes, less sensitive brakes and acoustic noises, care needs to be taken to check whether the brake drive has been badly worn or the brake hooves have been overwhelmed, leading to poor and effective matching of the hooves and discs, as well as to check whether the brake oil is too dirty or too thin or too thick. In addition to the above, there is a need to check the brake subpumps at specialized repair plants, which could be too tight a brake line, resulting in a quick wear and tear of brake plates and affecting the effect of brakes。
Zhang zhihong, director general of post-sales services, easted motors sales limited, indicated that the above problems required the replacement of larger, more sensitive brake plates with the help of professional maintenance staff, or replacement of original plants of guaranteed quality, professional factory brakes and brake drums, or replacement of new brake oil。
Leakage
Problem performance: leak oil, burner oil, leak in water tanks, cooling fluid, etc
Typical vehicle types: fox, bmw 320, yakoh, maiteng, benteng b70, new guinness, 307, alice, qqueen, odie a6
I don't know
The oil spill is a common problem in many vehicle types, and the owner should, in response to the alarm from the failure light, be careful to self-inspect the machine to see if there is any shortage of oil. In the summer, hot weather and oil spills have been the trigger for many spontaneous combustion incidents。
There are a number of reasons for the oil spill, and experts from the department of services, after a mass sale, have indicated that it is likely that most of the vehicles may have leaked oil as they travel on the puddles and bumps on the road, either as a result of a sharp bumping of the chassis, or as a result of a drag, leading to a break in the shell below the chassis, or tilting and easing。
The above-mentioned problems require timely self-inspection and prompt check-ups at 4s stores or specialized maintenance shops, timely replacement of damaged components such as oil casings, tightening of the bolts in various parts and timely replenishment of oil。
In addition, a number of popular vehicle types, 1. 8t and 2. 0t, as well as bmw and parts of japanese-born cars, are often burned with engine oil, i. E., adding oil is quickly depleted without a leak. The most common of these problems is the audi a6 model, with poor cylinder sealing being the main cause of these problems, which may be due to excessive wear and tear or the failure of the gas-barrel seals, as well as to congestion of roads and loss of oil lubrication. The problem could be solved by the use of additives to reduce friction resistance and enhance sealability, although the most fundamental approach would be to completely replace damaged cylinder components。
There are also water leaks in tanks due to congestion or fractures in catchment tanks or drainage pipes, and possibly to the poor quality of anti-freezing fluids or long-term corrosion resulting in the corrosion of parts of the connections。
6 electronic malfunctions
Problem performance: bad oil table, cdmp3usb does not read disks and failure lights such as car computers are frequent
Typical vehicle type: audi a4, ghilda, tianjin, lexus is200, fox, new junta, flag cloud, 307, alice
I don't know
The customer manager of the post-sales services department, gordo, stated that the oil table was not necessarily a problem for many car owners and that in many cases it was volatile, so that the 4s store could push forward, causing problems for claims and repairs. This problem is mainly due to problems with oil slicks and slide resistance in tanks, as well as failure of pumps. In general, with the exception of the quality of individual vehicles themselves, most of the models leave the plant without problems with the oil table. Problems in its use were mainly due to the addition of low-notation oils, which led to impurities in sedimentation, which affected the detection of oil floats and slide resistance; in addition, overfueling affected the internal gas pressure of the tanks, which caused the oil floats to suffer from measurement failures; not only were the pumps exposed to dissipation in the air, but the air and impurities could also cause the pumps to malfunction as gasoline entered the pipeline。
Many models now add usb-reading mp3 songs, and so on, the quality of disks, the ability of cds to correct errors have a direct impact on mp3 songs, and many car manufacturers need to improve the quality of their components if they are to use assured disks, players, etc. In addition, when the six cds are used, care should be taken to put them on a disk, and then the green light will go up and in and out of the way, and they will be vulnerable to damage。
The reasons for the failure of the computer lights in a car are numerous, such as the fact that the engine light alerts may be due to quality problems in the oil, the failure or disruption of the circuit system, the failure to modify the circuits, the gaseous lamps, etc., or the failure or burning of the cylinders, insurance etc。
7 car windows
Problem performance: automatic fall, slow reaction, non-up or non-up of electric car windows, sound and perturbability
Typical vehicle type: flag cloud, qqq, mercedes ml 350, polo, same jump
I don't know
The automatic drop in electrical windows during the lifting process was caused mainly by two factors, one by the failure of the electrical window and the second by the error in initialization of the electrical window. Since the electric window is new, the problem is just an initialization error. The initialization of the electrical window caused the electrical window control module to fail to accurately measure the position of the glass operation, and the glass operated close to the highest point without being able to exit the handler control, resulting in the control module operating close to the highest point, initiating the handler function and lowering the glass. Therefore, the electrical window system needs to be initialized using a diagnostic device。
There are many main reasons for the slow reaction of electric windows, such as insufficient voltage of electric cylinders, the ageing of window glazing to block the tracks of glass, the distortion of the door to distort the position of the electric shaker, and poor exposure to electric window switches. There is not enough voltage, so there is not enough power in the car window. The ageing of the window tape blocks the tracks of the glass, and increases friction when the glass rises. The deformation of the door distorts the position of the electric shaker, the fixed position of the glass is not on a parallel side, and some positions are frictioned with the door as it rises. In case of poor exposure to electric window switches, it is recommended that the system be checked at the vehicle maintenance station。
Air conditioning issues
Problem performance: slow response, non-refrigeration, leaks in cars, noise
Typical vehicle type: autumn, chang ansung, mir, jedda, a5, flag cloud
I don't know
According to a maintenance expert in chire, less than optimal refrigeration is a common problem with air conditioning, and it should first be stated that the effects of car air conditioning cannot be compared with those of domestic air conditioning。
Why isn't it working? There is currently no uniform standard. Generally, when air conditioners operate at a speed of 1,000 turns/minutes at 30 minutes when the doors and windows are sealed and the body is kept warm, the temperature difference between the inside and the outside of the vehicle is 10°c or more, which may be considered ineffective。
It is possible to check whether the windmills are functioning properly, check the air conditioner control boxes if they are not, check whether fuses, relays or relays have been burned, or check whether the windmills that are not. If the wind machine works properly, it depends on whether the condenser is dirty, and if the area is covered with dust and dust, it can significantly affect heat dispersion. Wash it with fresh water and turn off the air conditioner when cleaning. It is important to note here that the condensers and the evaporation units should be regularly washed backwindows。
Also, air conditioners typically require re-added refrigerants, refrigerated oils and replacement of dry filters for one year. If you do these maintenance, you are advised to go to a professional factory or a reputable repair site. Because the price is second, it'll damage your air conditioner if you don't do it right。
If the ac switch is open and no response is received, check if the ecd fuse is intact and the wire plugs are loose. If the switch is turned on, the work is stopped shortly after, and the first check is if the condenser does not turn or if it does not. If wind machines routinely re-check the system for abnormal pressures, this is too much to indicate over-refrigerant or blocked or condenser dissipation, and too low to indicate inadequate refrigerant or system leakage. The main route of the condenser was generally missed because of the large number of connections and proximity to the ground, which made the sandstone vulnerable to damage。
If the air conditioner functions with an acoustic sound, it should immediately determine where it originates and then stop and check. The main result is a compressor suction or belt, which should be replaced and properly installed by checking whether the belts are damaged or tilted。
