Good driving habits to prolong the service life of the battery

On the basis of the daily maintenance, but also to develop good driving habits, as follows:

1, do not frequent starting vehicles
Do not exceed 5S at the start of the engine, if the first start fails, don't rush to start again. From the working principle of the car, at this time, a continuous starting motor will certainly cause the battery over discharge and damage. So the time interval should be more than 15s. If the 3 time is still a failure, use the Auto Diagnostic Tool to find out the reasons, troubleshooting.

2, under flameout state Do not use electrical equipment inside the car for a long time
This is often encountered in the daily use of cars, but also easy to overlook the problem. For example, sit in the car to rest, et al, to fuel many drivers turn off the engine and sat in the car listening to the radio or watch DVDs, so do the purpose of fuel is reached, but deeply hurt your battery. Correct method of use is stalled in a state of continuous listening to the radio to no more than 30 min, at the same time do not recommend use equipment such as car DVD in stall condition.

3, under flameout state try not to use external power supplies
External power equipment such as dust suction machine, a portable air pump, avoid by all means not to use in vehicle flameout state. As the power of these devices is bigger, use in a stall condition for a long time can easily consume battery power, and thus affect the normal starting of the vehicle. Can be used to Launch X431 V Pro or Launch X431 IV GX4 tool test battery working condition.

4, parking must turn off the lights and the car with electrical appliances
When parking stall, forget to turn off the lights, which is a lot of new car owners easy to make mistakes. After a night of consumption of the battery, at any time may not have electricity, can not start the car. Try not to use CD, cigarette lighter and other electrical equipment in the vehicle did not start. In the course of driving, the vehicle is also less used variety of automotive electrical appliances.

5, first close the air before flameout
Most of the owners are not accustomed to air-conditioning or allow air conditioning with the vehicle starting automatically after the start, which will cause the vehicle ignition switch every time, the air conditioning system will automatically start work, the consequences are directly lead to the vehicle instantaneous power load is too high, a long time will cause a certain loss of battery. Correct habits should be, every time to reach the destination, the first switch off the A/C keys, let the wind blow for a few minutes, to ensure that the air conditioning system internal drying, reducing the breeding of bacteria. Then turn off the air conditioner before the stall. Every time after restarting a car, air conditioning.

In short, general automotive battery life in 2 years or so, if the use of Autel MaxiDas DS708 or Xtool PS2 tools to maintain proper maintenance, up to 3-4 years. We understand its function, on the basis of proper maintenance, and can develop good driving habits.

Regularly check car shock absorber to ensure driving safety

Automobile shock absorber is one of the key parts of the car body, for driving safety is very important. With a period of time, be sure to use OBD Diagnostic Tool to check the shock absorber, timely repair and maintenance.

Car shock absorber if there has a leakage phenomenon, for the shock absorber is concerned, is undoubtedly a very dangerous thing. So, once the discovery of oil spills, we must make timely remedial measures. Focus of the inspection items in the oil seal, seal gasket rupture damage, storage cylinder cover, check the failure of these parts of the nut loose.

If discover leak, first tighten nut cylinder lid, but if shock absorber still leak oil, may be damage of oil seal, seal gasket failure, a new seals should be replaced. If still can't eliminate the oil spill, should pull out of the damping rod, if feel the hairpin or weight, reuse Launch X-431 PADII or Launch X431 IV GX4 tool to check whether the clearance between the piston and cylinder is too large, with or without shock absorber piston rod bending the piston connecting rod surface and the cylinder have scratches or marks.

If the damper does not leak phenomenon, should check the damper connecting pins, connecting rods, connecting hole, rubber bushings and other damage, sealing off, break or fall off place. If these were normal, should be further decomposed damper, check with the gap between the piston and cylinder is too large, cylinder with or without injury, the valve seal is good, whether the valve flap and the valve seat fitting closely, and whether the presence of shock absorber spring is too soft, or broken, grinding according to the circumstance or change a way to repair.

In addition, the shock absorber in the actual use of the sound of the failure, which is mainly due to shock absorber and leaf springs, frame or axle, rubber pad damage or fall off as well as the shock absorber tube deformation, oil shortage and other reasons, should identify the reasons, to be repaired.

Shock absorber in the inspection after repair, then use the AUTOBOSS V30 Elite or Xtool PS2 tool to check shock absorber performance, in order to ensure the maintenance effect is good, to ensure the normal use.

How to buy automotive air conditioning filter and refrigerant

Some owners for air-conditioning system maintenance, how to choose the right accessories to do air conditioning maintenance will encounter many problems. Due to the owners of vehicles are not familiar with, and don't want to use Auto Diagnostic Tool to check, so here we give you a introduction to buy these accessories:

1. How to buy air filters?
Air filter: quality of original brand quality long-term air conditioning filter with respect to the poor quality of ordinary Deputy plant air filter, in the service life and impurity filtration efficiency to far wins a chip. Can guarantee the higher impurity filtration efficiency and extend the maintenance cycle.

2. Refrigerant How to choose?
Refrigerant: Pure brand R134a environmental refrigerant, it can ensure 2--3 years of life. Currently on the market of the refrigerant uneven, some good and some bad, media have exposed automotive air conditioning refrigerant sample test pass rate is currently less than 10%. If you use of counterfeit refrigerant in a short time can refrigeration, but long-term use, light will produce refrigerant leakage, resulting in automotive air conditioning and refrigeration effect is not good, will lead to serious damage to the air conditioning compressor, if use Launch X431 V Pro or Launch X431 IV GX4 tool to check in advance, can quickly check out the fault. So when buying refrigerant, must pay attention to choose the high quality brand pure refrigerant.

Buy air filters, refrigerant and air conditioning cleaning agent must pay attention to product quality, quality air filters, air conditioning refrigerant and air-conditioning cleaning agent can play a very good protection, increase of air conditioning refrigeration effect, kill in air conditioning mold and bacteria, eliminate odor, recovery and the freshness of the air inside the car, but inferior air filter, refrigerant and air conditioning cleaning agent not only can not achieve the effect, but will damage parts of the air conditioning system, use the Autel MaxiSys Pro MS908P or Autel MaxiTPMS TS601 tools to check parts of the air conditioning system performance, inferior products will reduce the service life of the air conditioner and the human health will be affected.

Audi A6 engine abnormal sound fault analysis

Audi C5A6 equipped with 1.8T engine and automatic transmission, driving mileage of 50000 km. Car owners reflect the engine in 2,3 gear acceleration have abnormal noise, the abnormal noise has lasted about half a month's time, through the OBD Diagnostic Tool to check, the sound becomes apparent.

After testing, in 2, 3 block accelerated heard engine abnormal noise, listen to the voice really like engine knock, but the power of the engine were not affected by any effect, accelerate the engine sound all normal. Combined with the failure analysis, the engine at 2,3 gear acceleration can send different sound There are several reasons:

(1) variable valve timing mechanism fault. Because in the 2,3 gear acceleration engine has entered the medium-load conditions, according to the characteristics of the engine, the valve timing should have entered the adjustment position, adjust the mode by changing the position of the chain tensioner to achieve. According Launch X431 V Pro or Launch X431 IV GX4 tool check, found that when the chain camshaft adjustment, if the chain tensioner lack of strength will make the chain in a relaxed state in the adjustment process and beep.

(2) Since the engine knock sound is generated. That there are several possibilities: ① fuel octane low lead to knock. This car's engine may be use 93 unleaded gasoline, it is best to use 95 unleaded gasoline, otherwise it will produce detonation. ② ignition timing is premature detonation. To further understand the failure, you can use Autel MaxiScan MS509 or Autel MaxiScan VAG405 tools to detect, which can quickly check out the car parts problem.

How to check the working condition of automobile shock absorber

Automobile shock absorber is mounted on an automobile chassis parts, it is used to shock absorption, simply put, is in the car through the rugged road, shock absorbers allows occupants to reduce the bumpy feeling, also can effectively keep the car running smooth. Automobile shock absorber is also have the use fixed number of year, use after a period of time may fail, you can use Auto Diagnostic Tool to check the performance of automotive shock absorbers, following will teach you how to check the car shock absorber the working conditions.

To determine if there is no damage automotive shock absorbers have a good way, that is in the ground at low speed, and then brakes, if you feel the car shake very badly, that's the shock absorber problem, or when driving in uneven road , the body feels a strong sense of bumps, it is also possible that poor shock absorber effect. In this case should go to the 4S shop, using Launch X431 IV GX4 or Launch X431 GDS professional tools overhauled.

If you want to check the shock absorber, we can first and the lower end of the shock absorber fixed in a vise, with hand drawing compressed several times, the normal shock absorber should have certain damping force, and to the tensile resistance should be greater than the compression resistance. If the unstable or no resistance may shock absorber lack of oil or damaged parts, should overhaul or replacement parts.

If only one side of the shock absorber to fail, it is suggested that the two sides of the change together, it is no use in a separately. Change is the need to use Autel AutoLink AL439 or Autel AutoLink AL609 tool to check, one can check whether automobile shock absorber has a good working, by hand Press a few bumper car, if the car can play two or three times, the automobile shock absorber works very well.

Three kinds of methods to solve the problem of car horn

The horn is a frequent use of the device while driving, if the speaker fails, it will be very difficult when driving. Sometimes honked the horn, the sound is very hoarse, and even a little voice at all. We need to use the Auto Diagnostic Tool timely detection, we take a look at how the horn works. When the horn button is pressed, the battery current will flow through the loop on the horn relay solenoid, solenoid relay attract dynamic contact switch is closed, current will flow to the speaker place. Electromagnet current work inside the horn, so that the diaphragm vibration sound.

According to the author's experience, many faults related to the speaker, problems arise fault is often the horn itself . Especially flawed speaker installation location of some design, when it rains very easy make the speaker wet in the rain, causing damage to the speaker. When the speaker does not ring, common failure parts are nothing more than 3 points, that horn itself, horn switch contacts and horn line, when a fault occurs can be used Launch X431 GDS or Launch X431 IV GX4 tool to check the following steps:

(1) sometimes does not ring. Press horn switch, if the horn is sometimes loud, sometimes does not ring, mostly inside the horn switch contact contacts well, some of them are horn itself.

(2) voice hoarse. Mostly due to poor contact plugs, especially the various contacts around the steering wheel, as a result of frequent use, easy to make contacts to wear.

(3)Completely does not ring. First check to see if the fuse is blown, then unplug the speaker plug, use Autel MaxiSys Pro MS908P or Autel Maxidiag Elite MD702 tools to detect whether horn switch is electricity. If there is no power, check the horn and horn relay harness; if there is electricity, it is the speaker itself is the problem, then you can try to adjust the adjusting nut on the horn to see if sound, if still does not ring, you need to replace the speaker.
