What is the reason for the sudden stalling of the Audi A42 0 driving?

Hello, there are many possibilities: 1. Excessive carbon deposition in the throttle, idle motor, air intake tract and combustion chamber will cause the engine to stall. Excessive carbon and dirt deposits in the intake tract and changes in the cross-sectional area of the air passage make it impossible for the control unit to accurately control the amount of air intake at idle speed, resulting in the mixture being too thick or too thin, and causing the engine to not start.

Second, because of the poor performance of the electronic control system to maintain constant pressure and low fuel pressure, the fuel injection atomization is poor, resulting in difficult starting. Third, the engine should be turned off during the hot car, first of all, check the carbon deposition of the throttle body, and secondly, the crankshaft position sensor itself has abnormal resistance, resulting in the disappearance of the crankshaft speed signal after the hot car, resulting in the engine stalling; Fourth, the gasoline pump itself is faulty, and the resistance value changes after a long working time, which cannot provide normal fuel pressure for normal operation, causing the engine to heat up and stall; 5. The ignition system is faulty, the ignition module is overheated and cannot work normally, the ignition voltage fails, and the engine stalls; 6. Abnormal throttle signal voltage and abnormal engine computer control will cause the vehicle to stall while driving; 7. There is a virtual connection phenomenon in the line, resulting in occasional engine stalling, and this kind of fault needs to be comprehensively inspected.

Hello, can you still fight when the fire is turned off?

The reasons for the sudden stalling of the car are:

1. Driving skills are not skilled;

2. The oil used is unqualified;

3. The oil circuit is not smooth;

4. The engine idle speed is too low;

5. Lubrication or circuit problems;

6. Low pressure; 7. Device failure;

8. Oil circuit failure.

Flameout troubleshooting method:

1. For novices, turning off halfway is not a new topic, and the main elimination method is to improve their driving skills after rapid running-in.

2. Use high-standard, high-quality and qualified fuel.

3. Clean the oil circuit thoroughly, including fuel injectors, throttles, fuel tanks, etc. It may be that the quality of the oil you add is not up to par, there is too much grease, the oil path is blocked, and the oil supply is not smooth.

4. The main reason for the failure of the car to stall in the idle state is due to too much dust in the air, and there is a lot of dirt deposited at the valve core of the idle motor and the throttle seat when the engine is running. The solution to this problem is simple: just clean the idle motor.

5. Long-term parking of the car is not used. In fact, it is important not to park it for a long time. In case of a long parking time, you should do a thorough maintenance before re-use, change the oil, filter, etc., and check the fuel, electrical circuit, etc. as appropriate.

It is possible that your vehicle is due to lubrication or electrical problems due to prolonged parking.

6. If the ignition is out due to low-voltage power failure, you can mainly check the ignition and starter switches and fuse boxes at this time.

7. The sudden shutdown of the car while driving may be a device failure, and the problem is generally the ignition coil, capacitance electric, and electronic ignition module. It starts at the beginning, turns off after a while, and then starts again and turns off again.

8. The sudden shutdown of the car while driving may be a fault of the oil circuit, the gasoline pump is damaged, the oil pipe is broken, the oil inlet of the carburetor is blocked, and the fuel tank is out of oil. But in this case the car can be restarted, but it is difficult. Ignition system, engine overheating and detonation system will turn off if there is a problem. Hope!

The 2017 Audi A4L emits a very loud alarm sound when it is parked normally, which means that the vehicle's electronic anti-theft system is malfunctioning, and the Audi A4L electronic anti-theft system needs to be re-matched to eliminate this problem.

The specific steps are as follows:

1. Open the door on the driver's side of the car.

2. Press the brake pedal of the car to prepare to start the engine.

3. Press the car's one-button start button.

Fourth, the car's instrument lights are all lit, which proves that the car engine has started.

5. Press and hold the lock button of the driver's door without releasing it, and continue to press and hold for more than 10 seconds to complete the matching.

Hello, any of the four doors and the lid and trunk lid will alarm if they are not closed. Damage to the electrical parts of the lock blocks of the four doors, the lid lock and the trunk lock block will also cause the alarm to be called when the car is locked.

Generally, in addition to the lack of driving skills, it is a problem with the car engine or oil circuit. Audi A4L suddenly turns off when driving, remember not to hit the direction, press the double flashing indicator to prompt the car coming from behind, and then stop slowly on the side of the road to check the vehicle condition.

You can turn on the ignition switch of the car, observe whether the indication of the gasoline gauge is normal, and then see if there is still oil in the mailbox, if the remaining oil in the fuel tank is too little, it will also cause the engine to fail to start normally, because the fuel consumption of the engine is very large, the fuel consumption will be quickly exhausted.

In addition, the fuel gauge of some cars is not very accurate, and the fuel tank may be out of gas, but the fuel gauge still shows that there is oil, which should also be considered.

Disposal:

If the vehicle suddenly turns off during driving, first of all, of course, do not panic, try your best to stabilize the car and do not play the direction, turn on the double flash, with a little braking depending on the situation, the manual transmission vehicle first turn on the double flash to remind the passing vehicle to pay attention to avoid, step on the clutch, control the foot brake, use inertia to slide slowly, and control the direction to stop on the right as much as possible.

If the engine stalls due to the operation of the shift discomfort and the force is too small, the engine can be started again, and the driving can continue after starting; Do not start the engine again if the engine is stalled for non-operating reasons, and check the cause of the stall to avoid causing greater engine damage.

If it is an automatic transmission car, turn on the double flash, stop on the right as much as possible, pull up the hand brake, and set up a fault triangle in front of the car, 50 meters (daytime) and 100 meters away from the car to remind passing vehicles to pay attention to avoidance, get out of the car to check and turn off.

Summary. In the second case, because the Audi A4L has an ultrasonic alarm function in the car, as long as the car is locked, the car will automatically alarm when there is ultrasonic or sound in the car. For example, after getting out of the car, if there are children in the car, pets in the car, or even flies and mosquitoes in the car, the car will call the police by itself, prompting the driver that there are creatures in the car, pay attention to take them out, and prevent heat stroke or suffocation of creatures in the cockpit caused by overheating in summer.

If the vehicle is changed to a police use, it is important to check the vehicle for living organisms. Or go to a 4S store for help.

One is the main driver's door, the passenger door, two rear doors, the front cover lock, and the trunk lock. After parking, due to improper closing or broken lock switch resulting in poor contact, the car alarm system will call the alarm. If you encounter alarm problems after locking the car, first check the four doors, engine cover, and rear bush trunk cover, and then switch to see if it has been closed in place.

In the second case, because the Audi A4L has an ultrasonic alarm function in the car, as long as the car is locked, the car will automatically alarm when there is ultrasonic or sound in the car. For example, after getting out of the car, if there are children, pets, or even flies and mosquitoes in the car, the car will call the police to remind the driver that there are creatures in the car, and pay attention to taking them out to prevent heat stroke or suffocation from overheating in the cockpit. If the vehicle is replaced by a police officer, it is necessary to focus on checking whether there are any creatures in the car.

Or go to the No Regrets 4S store for help.

It should be that the anti-theft device is too sensitive.

Audi A4 uses a key start to realize the start and start operation of the vehicle, the driver only needs to wear the vehicle's smart key on the body, the specific operation steps are as follows:

1. Open the driver's door.

2. Press the brake pedal of the vehicle.

3. Press the one-button start button of the car.

4. At this time, the instrument lights up and the vehicle starts.

5. Press the one-button start button again to turn off the engine.

Notes:1. The smart key should be in the car.

2. The brake pedal must be pressed when starting.

The reason for the sudden flameout.

1. Engine stalling is one of the common reasons:

a. Engine stalling is one of the common reasons for land wind stalling, which is manifested as the unstable operation of the engine when idling, and the exhaust pipe makes a purring and purring sound.

Solution: The main cause of the fault of the car stalling in the idle state is due to too much dust in the air, which can be solved by cleaning the idle motor.

b. The engine is shaking, followed by stalling, and the second start will be normal!

Solution: Replace the gasoline filter, clean the throttle, and check the spark plug combustion. Or you can turn the ignition switch to the power-on self-test state first, stay for dozens of seconds, let the oil, oil pump or something run for a while, and then ignite.

2. Troubleshooting method for automatic transmission car shutdown:

Pay attention to the place: for the phenomenon of automatic transmission car stalling, it is mainly caused by the use of inferior fuel.

Practical operation: Hold the steering wheel with your left hand to stabilize the direction because there is no power assist, so you must stabilize it hard, press the brake with your right foot to reduce the speed as much as possible, and then quickly hit the AT gear to N gear, then take the key back one notch, and then re-ignite, and then restore the AT gear to D gear for normal driving.

3. Troubleshooting method for manual transmission car stalling:

Solution: Clean the oil circuit thoroughly, including fuel injectors, throttle valves, fuel tanks, etc. It may be that the quality of the oil you add is not up to standard, there is too much grease, the oil path is blocked, and the oil attack is not smooth.

4. Long-term parking is not used

Land breeze flameout is closely related to long-term parking and non-use, because long-term parking can lead to lubrication or electrical problems.

Solution: Do a thorough maintenance before reuse, change the oil, filter, etc., and check the fuel, circuit, etc. as appropriate.

Incorrect steering wheel operation can cause problems such as steering noise.

The main reasons for the general car stalling:

1. Use low-quality fuel. Once the automatic car stalls, the main reason is the use of inferior (not up to standard) fuel, which in turn causes the engine to depot and stall.

2. Engine computer failure. From the point of view of kilometers, after using the car for a long time, the possibility of engine computer failure will be relatively large, once the engine computer fails, it will cause the car to stall, which is a problem of control. Just like the human brain, when there is a malfunction, the body "goes out".

3. The driving skills are not proficient enough. The driver's unskilled driving skills and improper operation will also cause the car to stall.

4. Multiple cylinder failures at the same time. It is possible that due to the failure of the spark plug or the high-pressure bag, one or more cylinders will not ignite, resulting in a flameout. However, only the failure of multiple cylinders at the same time and non-ignition can cause flameout, so there is such a possibility, but the probability is not large.

5. The engine itself fails. Damage to the engine idle motor or the wiring of the idle motor, or a problem with the idle control module in the engine's electronic control unit (ECU). The possibility of the engine itself failing is extremely high among the many reasons why a car stalls.

6. Oil pump failure. The stuck oil pump or the failure of the oil pump itself will cause a sudden lack of oil supply, and no oil supply will easily cause the car to stall.

Audi A4 uses a key start to realize the start and start operation of the vehicle, the driver only needs to wear the vehicle's smart key on the body, the specific operation steps are as follows:

1. Open the driver's door.

2. Press the brake pedal of the vehicle.

2. The brake pedal must be pressed when starting.

The 2017 Audi A4L is bent and usually parked to emit a very loud alarm sound, and the occurrence of such a false skin situation indicates that the vehicle's electronic anti-theft system is faulty, and it needs to be rematched with the Audi A4L electronic anti-theft system to eliminate this problem.

The specific steps are as follows:

1. Open the door on the driver's side of the car.

2. Press the brake pedal of the car to prepare to start the engine.

3. Press the car's one-button start button.

Fourth, the car's instrument lights are all lit, which proves that the car engine has started.

5. Press and hold the lock button of the driver's door without releasing it, and continue to press and hold it for more than 10 seconds.

The reason why the Audi A4 turns off and rests in the car is that the alarm sound is caused by the failure of the car's engine.

The solution is: if it is the engine failure of the car, you need to go to the 4S shop or repair shop of the car in time to repair the engine of the car to solve the problem of engine failure of the car.

Sensors include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc., when these sensors are damaged, poor contact or signal interruption, the ECU of the car can not accurately obtain engine data, at this time it will cause the engine fault light to turn on. Poor engine maintenance is the most common cause of engine failure to light up.

Cause of failure:

1. Engine fault light.

2. The battery lamp is also one of the common fault lights.

3. Oil alarm light.

Solution: 1. If the engine fault light, yellow light - on behalf of the fault, but the vehicle can continue to drive, please go to the repair shop as soon as possible for inspection and maintenance.

Red light - means that there is a fault, please stop immediately and call for help**, at which point the vehicle cannot continue to drive to avoid occurring.

Dangerous. 2. If the battery light is on, it often indicates that the car is about to run out of power or the generator is malfunctioning. The first thing to do is to observe the color of the battery observation hole (electric eye), different colors represent different use conditions of the battery.

3. If the oil warning light is on, it means that the vehicle must have lacked a large amount of oil, in order to avoid excessive losses to the engine, please add the same type of oil as soon as possible (especially for turbocharged engines, the lack of oil will cause great damage to the turbocharger and the engine.)
