Why does the Volkswagen Sagitar fail to fail? The mileage of the car is less than 40,000 kilometers
Cars can accurately grasp the movement of cars, mainly by monitoring operating data by various sensors.
The sensor can transform the various operating information information of the car, such as the speed of the car, the temperature of the various media, and the operating conditions of the engine, and transform it into an electrical signal to the ECU (the car’s “driving computer”) for analysis.
If there is a deviation, then the ECU will issue the command to automatically adjust,
However, once the ECU’s small assistant sensor is broken or faulty, the corresponding device may work abnormally, and the car cannot work normally, and the impact is still great.
Generally, the small assistant sensor of the ECU is: oxygen sensor, ABS speed sensor, water temperature sensor, electronic throttle pedal position sensor, etc.
Today we mainly talk about ABS speed sensors.
In the past two years, we often see about some car owners’ complaint platforms and car forums, and we often see about
“Volkswagen Sagitar ABS sensor failure”
The hot topic of discussion causes trouble for many car owners.
Mr. Wang’s car is the 230TSI DSG comfortable type of Volkswagen Sagitar. The number of kilometers is not long. It is less than 40,000 kilometers now.
There was a car that didn’t move much. Recently, the car was found on the dashboard, and the body was stable, the tire pressure lamp, and the steering wheel warning light was bright yellow.
Later, I opened the repair shop,
After confirming the maintenance master, it is the ABS sensor failure. The specific round must read the computer to confirm it. The probability is to change the sensor.
When he encountered this, Mr. Wang was quite depressed. Because he usually loved the car and did not do anything harmful, the failure was very troublesome.
Xiaobian asked the owner of various platforms to ask questions and found that the frequency of the sensor of ABS is quite high.
Especially 2015 to 2018 models.
Indeed, Sagitar ABS sensor failure is a common problem.
So why do Sagitar sensors frequently fail?
Let’s analyze the reasons and solutions.
What is the cause of frequent failure of Sagitar sensor?
At present, the manufacturer has not made any clear explanations of this, but it is just a common phenomenon.
However, according to the maintenance experience of most car owners, the reason for the general sensor is that after the vehicle passes through a certain kilometer, the sensor occurs in quality problems and causes failure.
How to judge whether the ABS sensor is broken?
1. Read the fault code of the fault diagnosis instrument:
If there is a problem with the sensor, the fault code will occur in the ABS computer, and the fault light on the instrument will light up.
2. On -site braking detection:
In a place where the road is good and wide, speed up the car to more than 60. It is best not to exceed 80, and then step on the brakes to the end.
If the wheels are killed and the brakes are not frustrated, it indicates that ABS fails, which is usually caused by the damage of ABS sensors.
3. Use a multimeter to measure the voltage/resistance of ABS sensor:
Rotate the wheel with a speed of 1R/s, the front wheel
The output voltage should be 790-1140mv
The rear wheel should be higher than 650mv,
If it does not meet this scope, it indicates that there is a problem with the ABS sensor.
The resistance value of the ABS sensor is generally between 1000-1300Ω. If it does not conform to this range, it indicates that the ABS sensor has problems.
The problem is, the ABS sensor is broken,
Can the car continue to drive?
The ABS sensor is broken, and you can continue to drive, but the ABS system does not work, and the wheels will be held to death during the brake. Once the wheel is hugged, it will be difficult to control the direction and easy to slip and get out of control. This is extremely dangerous.
Therefore, when the ABS fault light is on, if it fails to deal with it in time, be careful to drive to avoid sudden braking.
Timely processing to make driving safer and more at ease.
Although Sagitar’s ABS sensor failure is very troublesome,
But the problem appeared, we can only solve it,
Therefore, the sensor still needs to be replaced in time.
How much is Sagitar ABS sensor?
A ABS sensor of Sagitar is different according to the quality of the sensor and the location of the repair, and the price will change accordingly. If you replace it in the 4S shop, an ABS sensor plus working hours
About 500-800 yuan.
However, if it is replaced in the repair shop, the price is about about
Between 100-150 yuan
Essence If you change it yourself, you only need the material fee
Around 50-100 yuan
In fact, it is relatively simple to change a sensor,
If you have a little hands -on ability, you can replace it by yourself according to the following method.
1. First, fight the direction of the wheel of the vehicle to the opposite direction,
For example, if a failure appears on the right, the steering wheel is killed to the left.
2. Subsequently, the vehicle topped the vehicle with a jack configuration, and then removed the wheel hub.
3. Find the location of the sensor,
After wiping the surrounding dirt, use the inner hexagon wrench to remove the fixed screw.
4. Use a small screw knife to buckle the small buckle on the sensor,
Separate it from the thread sleeve and install the new sensor.
5. After installing the sensor, restore it according to the steps of disassembly to complete the sensor to replace it.
Although the complexity of the operation is low, if some riders are not familiar with the operation or the ability to do well, it is best to replace it to a professional repair shop or 4S shop.
# Kind tips
ABS is a very important system for cars. The role is to prevent the wheels from killing the wheels when braking the emergency brake or ice and snow, and avoid the vehicle out of control. For the failure of the sensor, you should discover and deal with it in time, and do not lose a lot.
