According to the temperature replace oil

Most of the car owners are maintenance according to their car driving mileage, for some owners, if not achieve the required mileage and also maintenance, but also need to use the OBD diagnostic tools for vehicle maintenance, especially the temperature low special attention to.

Some people may ask, why did not achieve mileage also need to do maintenance. This is one of the main secret lies in the oil. Maybe the maintenance on the car we usually do not notice, regardless of what kind of brand of oil drums on top will have some numbers. For example 5W / 40,0W / 30,10W / 30 and so on. In fact, these labels and seasonal changes have a direct relationship.

W represents a numeral of Winter (Winter) Abbreviation, digital W before the smaller, the smaller the low-temperature viscosity, the better the low temperature fluidity, the lower most suitable temperature. And behind the figures in general are: 20,30,40,50, the larger the number the greater the viscosity.

5W oil winter low temperature can reach minus 30 degrees Celsius, the degree of resistance to low temperature oil 0W label can reach minus 40 degrees Celsius, these two labels to meet the basic situation in most parts of hypothermia. But some of China's northeastern extreme cold areas, hypothermia usually can reach minus 30 degrees or lower. If the last oil change labels for 5W or 10W oil then we would re-replacement, or cause severe wear in winter oil illiquid car's engine will shorten life. If you do not know when to change the oil, you can use the Launch Diagnostic Tool OR Autel Diagnostic Tool, to help you diagnose any problems with the car.

Audi automobile safety airbag use guide

FAW Volkswagen production Audi A6 sedan, airbags as standard. For the repair of the system failure, not only need OBD diagnostic tools, but also need to grasp the system composition, working principle and correct detection method.

Detection method and the matters needing attention in the process of maintenance Airbag system installed on the Audi A6 sedan with a self-test function; every time the car will perform a self-test of the system; once the system detects a fault, the red light on the instrument AIR BAG will be president of the light. If the light is not on when you turn on the ignition switch, or in motion lights flashing, were indicative of a system failure, then the system needs to speak the line fault detection. Fault diagnosis of the system can only use special diagnostic VAG1551, VA G1552, V AS5051 or other Autel Diagnostic Tool and Launch Diagnostic Tool diagnosis.

Further, the system and other electronic control Audi vehicle systems, by using a dedicated diagnostic equipment, can be queried, part number and fault diagnosis system software version of its system, the implementation of the final element, clear fault code, and to read the data block The control unit encoding functions, the system address code is 15.

In the maintenance of the system needs attention to some of the following items.
1) prohibits the trigger line for testing, namely the driver and passenger side airbags, front and rear seat side airbags, and seatbelt tensioners trigger directly measure its resistance.

2) removable front driver and passenger side airbags, you must turn off the ignition, remove the negative battery cable. Driver's side airbag folded down, should be properly placed, prohibiting anti-put throw with touch.

3) airbag control unit must be replaced in the following cases: the driver or passenger side airbag is triggered after the first; front seat belt tensioner or side airbag is triggered three times; electrical lines under normal circumstances, Launch X-431 PAD and Launch X431 IV GX4 Master diagnostic system can not enter or fault code is displayed as 65535. In addition, the replacement of the control unit should be encoded.

No matter what the car is on the airbag, just as a safety auxiliary devices exist, can not use it as personal safety is guaranteed. Therefore, in daily driving, we should pay more attention to driving safety, be sure to use a seat belt device, or car diagnostic tools add a layer of security protection key.

Four ways for maintaining automobile safe airbag

Airbags, as the name suggests is to protect drivers and passengers safe, safe driving, the airbag will not play a role, especially in the frontal crash once an emergency occurs, it will play a role to ensure the safety of your life. Therefore, understanding and careful maintenance of the car's airbags is one thing you can not be ignored.

First, the airbag is a disposable product. After the collision detonated, the airbag will no longer have the ability to protect, and to be sent back to repair factory to replace a new airbag. Due to the different models, the price is not the same as the airbag. Re-installation of a new airbag system includes sensors and computer controller, generally need about 5,000 yuan to 10,000 yuan.

Second, do not balloon in front of, above or near the place items. Because the balloon will explode in an emergency situation, so do not balloon in front of, above or near the place items to prevent detonation was hurt when the airbag occupant ejections out. In addition, the installation CD, radio and other accessories in the room, to comply with the manufacturer's requirements, not free to modify parts and lines fall within the scope of the airbag system, so as not to affect the normal operation of the airbag

Third, children have to pay attention when using airbags. At present, many airbags are designed for adults, including the airbag in the car's location, height. Balloon inflated, it may cause harm to the child in the front row. Suggested that children placed in the rear center position and secure.

Fourth, pay attention to the daily maintenance of the airbag. Mounted on the dashboard of the vehicle when the airbag indicator light, under normal circumstances, the ignition switch to the ACC position or the ON position, the warning light will shine about forty-five seconds to self-check, then turns off. If the warning light stays on, it means that the airbag system failure, you should immediately repair the airbag malfunction or misuse of the situation in order to avoid the emergence of pop.

Some OBD diagnostic tools will help you test out your vehicle on your own, for example: Launch X431 GDS, Launch X431 Diagun III, Launch X-431 PAD, Autel MaxiSys MS908 and so on.

Automobile appear 3 common problems after the rain

Condition 1: driving sideslip
Rainy days is slippery, the possibility of sideslip increase in traffic, in addition to good driving habits and skills, good brake with the state of the tire was the key to safe driving. The vast majority of car braking system is dual-pipes hydraulic braking vacuum booster. The brake fluid from transfer braking is extremely strong water imbibitions. If there is water into the brake fluid, in the process of braking, the high temperature of friction produces water vapor. And gas compressibility in the brake fluid is compressed, can cause brake failure and even failure.

The solution: some serious vehicle brake fluid bibulous, in the brake fluid oil droplets can be seen on the lid. So have to check the brake fluid during maintenance, to ensure driving safety. Once found the car brake fluid bibulous serious, should send professional repair shop in addition to the water.

In addition, before the rainy season if it is found that vehicle tire wear, loss of tire, and must be replaced. Someone to reduce tire pressure every rainy season, the purpose is to make the friction between tire and ground area increases, thus increase the adhesion, actually just the opposite, it is easier to cause the tire skid, keep the normal tire pressure is very important.

Condition 2: wiper failure
If you often drive a car in the heavy rain, the line of sight is not clear is the biggest hidden danger, the importance of wipers are evident. And at this point, if the wiper conditions such as vibration or have different ring, that you be careful, because it is likely to be in it to send warning to you.

Solution: increasing the monsoon rain must let the wipers to assume more responsibility, for wiper inspection and maintenance to be more careful. Because rainy days the road and the line of sight of them are good for driving, if the wiper cannot very good brush away the rain, it will be great danger to traffic, the wiper plays an important role, so more careful inspection and maintenance of it in place.

Owners themselves put wiper switch speed of various location, pay attention to the wiper is there a vibration at work or have different ring, check whether the wipers under different speed to keep a certain velocity, the status of the wiper and wiper strut uneven whether there is a swing or leakage phenomenon. Both fault in any kind of means that the wiper blade damage. At this time can be used, with finger touch on rubber wiper blades, check for damage and elasticity. If the crack of leaf aging, hardening, or, should be timely replacement. Replacement blades work is not complicated, can do it yourself. Remember to first figure out what kind of specifications of the car wiper blade.

Condition 3: rainy day engine start
In the rainy season is the most critical for cars "heart" - the engine maintenance. The owner on a rainy day when the engine is not easy to start with, sometimes even forced up, is also a whisper.

Solution: this problem from the ignition system is the biggest reason due to damp the leakage. Once found because of ignition system of the wet and cause adverse, engine ignition performance, can temporarily use dry paper towel or dry cloth to dry distribution plate and wire inside and outside, if because of aging leakage must be replaced immediately.

Rainy days also often wade, after wading car performance due to several water fell, serious can lead to the car can't run normally. This of course, also is most likely from the ignition system leakage caused by moisture. Because rain is the best conductor, turbid in electricity after water is likely to cause a short circuit.

If the move engine stalling doesn't repeatedly ignition start-up, should wait for a period of time or checking circuit, otherwise extremely easy to cause the engine scrap. When the car should be timely after smooth wading through the circuit equipment for maintenance, can with a paper towel or dry cloth dry circuit one by one to start again.

Here we recommend some OBD diagnostic tools can help you test your car by yourself, such as: Launch X431 V Pro, Launch X431 Diagun III, Launch X431 GDS, Autel MaxiDas DS708 and so on.

Three common problems that should be paid attention to in the summer driving

Prevention tire: tire pressure down promptly repair
The hot summer is high season car tire. Due to the high temperatures, low quality or if the tire itself tire pressure is too high, the tire after gas expansion will lead to a puncture. Therefore, we recommend that owners will be tire reduced by 10%, adjusted to 2.2 kpa.

Owners should pay more attention this season on tire maintenance, if damage is discovered, it should be promptly repaired or replaced. If you have patched the tire, it is best to put the rear wheels or as a spare tire. In addition, particular attention not to let the summer tires collision obstacle, because it is easy to make the tire sidewall injuries caused problems.

Reminder: If the tire which occurs in the driving, the driver applied the hand tightly control the steering wheel, slow step on the brake, the vehicle smooth deceleration stop. Do not be an emergency brake, because it is easy to cause the flick even rollover.

Water temperature exceeded: Timely parking thermal cooling
Summer car drivers who not only baked, vehicles will be unable to withstand high temperatures, excessive water temperature is relatively common, even "boil" boiling. Summer car owners should always pay attention to see when the water table, look at whether the water tank.

Driving, if you find the water table pointer nearing the red line, it should reduce the speed as soon as the car drove into a cool place to stop. To avoid engine damage, do not immediately turn off after stopping, but should let the engine idle for a period of time before.

If the water temperature is still not fall down, you should turn off the car, check the engine coolant. But be careful not to open the radiator cap immediately, otherwise it is easy to steam burns. If it is because of lack of coolant, it would first make up.

Reminder: If the water temperature is too high the phenomenon, do not let the car on long journeys, because for a long time with a lot of damage to the engine water temperature is not under normal circumstances; do not slow down especially not choose congested roads.

Auto ignition: Reducing modified periodically check
Prevent the car ignition; the most basic method is to periodically do maintenance to the car, check the engine, and an oil circuit, to see whether the aging and oil spills. Do not store in a non-standard vehicle repair or modification, because of some wrong operation of Luanda wires, easy to friction is not effective at a fixed, will be dangerous.

If the modified car, especially lights, sound, etc., should be comprehensive examination. In the hot summer, do not lighters, fragrances, air fresheners and other flammable items placed under prolonged exposure to high temperatures inside the car to avoid swelling caused by physical explosion sparking spontaneous combustion; After a long journey, it should be appropriate to let the car rest what to avoid overload.

When driving, vehicle owners should be aware of signs of spontaneous combustion, such as an odor, abnormal sound or vehicle electrical malfunction and so on.

Reminder: The best car standing on a fire extinguisher. Once spontaneous combustion, the first car in the right place few people pull over, turn off the heat, remove the fire extinguisher, look for fire points to the part of the cooling tank and burning fire to avoid explosion.

Here we recommend some OBD diagnostic tools can help you test your car by yourself, such as: Launch X431 Diagun III, Launch X431 Pro3, Launch X431 IV, Autel MaxiDas DS708 and so on.
