What happens when the Porsche Cayenne starts the engine and turns off and starts again, what happens

This problem should be caused by the failure of the electrical valve of the choke valve, the choke is an auxiliary equipment for cold starting, the main purpose is to increase the fuel injection of mixed gas, so that the combustion is more stable, when this component fails, there will be the situation you mentioned above, although you remove the carbon deposits of the throttle valve, the carbon deposits of the ternary, it will not help; This phenomenon is actually that when starting, the combustion is unstable, the engine shuddes and runs for a few seconds and then turns off, often after a few seconds of running, and at the same time, because of the failure of electrical components, the engine fault light will also light up, start the engine again, and the running time will be longer than the last time; But it will generally turn off, usually after starting 3 times, the temperature of the vehicle rises, at this time the engine is working normally, but the fault light is still on. Secondly, it may also be due to the unstable oil pressure caused by the failure of the fuel pump, but the probability of this occurrence is very low. It is recommended that you drive the car to 4s and check the fault** before concluding.

If a new car shakes at idle, it can be said that it is not good to burn, nor can it be said that it is carbon deposit, which will lead to carbon deposit for a long time due to poor combustion.

Poor combustion is directly related to the oil circuit. Carbon deposition does not mean that it will shake, but it will shake if it is not burned well. You can clean the oil road, don't look at your less kilometers on the oil road will be fine, this is not your decision, is the fuel company's excellent product decision.

The underground oil tank of the gas station should be cleaned regularly, not to mention the oil circuit of the car fuel tank, and what should the gasoline filter do if the fuel tank is absolutely clean. The fuel with impurities is pumped into the combustion chamber and shakes if it is not burned well. After encountering, the new car should pay attention to the moisture problem of the fuel tank and the impurities and excellent products of the oil circuit, and can be cleaned with Si Youpu additives to not let the problem continue and cause greater losses.

The reason why the car stalled and the engine still sounded:

1. Many car owners who lack experience in using the car will encounter a similar situation, thinking that the car will not work if the key is turned off, but in fact, it is not, in the case of high engine temperature, even if the car is turned off, the key is also withdrawn from the car, and the cooling system will automatically start to cool down the engine system, so it will be whirring, that is because of the sound of the electronic fan rotating at high speed.

2. After the temperature of the engine system drops, the cooling system will automatically stop working, which will last for three to five minutes. In addition to the engine, there are actually other electronic devices that will have this similar situation. Some luxury cars with sunroof ventilation systems usually continue to work for 10 to 20 minutes after the sunroof is turned off, so as to remove the overly cold or overheated air in the car and keep the temperature inside and outside the car consistent.

Summary. Hello, after the Porsche Cayenne is turned off, the horn is still buzzing, so this situation is generally a situation with electricity.

First, check whether the vehicle has any electrical equipment installed later? It is also possible that there is interference with the electrical equipment.

Second, if there is no one, then this situation belongs to the vehicle line, and the place where there is electricity needs to check the line.

Third, check the relevant body control module of the vehicle, if there is a problem, it needs to be repaired or replaced in time.

After the Porsche Cayenne turned off, the horn was still buzzing.

Hello, don't click to end, I'm textual to give you the full answer, 2-3 minutes.

Hello, after the Porsche Cayenne is turned off, the horn is still buzzing, so this situation is generally a situation with electricity. First, check whether the vehicle has any electrical equipment installed later? It is also possible that there is interference with the electrical equipment.

Second, if not, then this situation belongs to the vehicle line, where there is electricity, you need to check the line Third, check the relevant body control module of the vehicle, if there is a problem, you need to repair or replace it in time.

Turn off the stereo, the speaker is still thinking.

That's usually a line interference or a continuous practice.

It may be like what Douyin said above, the sound module in the back is flooded.

There is such a possibility.

It is necessary to replace the module or repair it.

Hello, this depends on the degree of water ingress of the module, if it is a slight water ingress, it can be repaired, if it is particularly serious, it can only be replaced.

Does the swap need to match or something?

In your experience, it's probably water in the back, right?

The possibility of water ingress in the back is the greatest.

If it is replaced, this is the corresponding match.

If the horn sounds, it means that the button is rusted or dirty and has poor contact;

On the issue of abnormal noise of automobiles, it is difficult for ordinary car owners to distinguish which ones are abnormal noises and which ones are reasonable abnormal noises. Only nearly 20% of the vehicles that went to the repair shop to detect abnormal noises really had problems. In the case of a turbocharged engine, there is a must be a difference between the sound and the sound of a naturally aspirated engine; Models with engine guards may also make noises due to friction; After some car owners come into contact with different cars, it is likely that due to their lack of understanding of mechanical knowledge, they mistake reasonable abnormal noise as a vehicle failure.

Therefore, learn to distinguish the abnormal noise of the car and avoid wasting time and energy.

How to identify the sound of a car:

In practice, due to the limitations of working conditions, the sound of the car can only be described and compared by judging the sound in daily life. For example, the "rattle" sound caused by the dry friction of the bearing, and the "click" sound similar to the small hammer hitting the cement floor caused by the excessive valve clearance.

1. Correctly distinguish between normal and abnormal sounds.

The vibration of each mechanism in the work of the car will emit a variety of sounds, but the sound does not mean that the car is faulty, in order to avoid unnecessary disassembly, we must first distinguish between normal sound and abnormal noise. The normal vibration sound of each system component (such as the noise on the surface of the engine), the impact sound of the gear when shifting, the intake and exhaust sound of Bili using gas as the working source, and the gear meshing noise are all normal sounds. Abnormal noise (abnormal noise) can be divided into slight noise, general noise and malignant noise according to the impact on the performance of the car.

Slight noise, such as the flashover sound of high-voltage electric leakage, the slight loose sound of rolling bearings, etc., the general volume is small, the degree of wear of the parts is not large, and there is no significant change for a long time, and this kind of fault can still maintain the normal operation of the car without repair.

3. When diagnosing abnormal noise, attention should be paid to creating good auscultation conditions and trying to eliminate the interference of other noises, so as not to affect the accuracy of judgment.

It is best to consciously amplify or reduce the sound, that is, use a screwor or other metal rod as a stestological instrument to contact the sound part to amplify the sound, or use a single cylinder fire cut-off method to reduce the sound to meet the needs of diagnosis. The auscultation site should be kept quiet to minimize human interference.

The squeaky sound of the Porsche Cayenne's speakers after a power outage may be due to a number of reasons:

The power supply is not completely cut off: The power cord may not be completely cut off, resulting in the speaker still having power and generating noise.

Loose wiring: It may be that the connecting wire of the speaker is loose or in poor contact, resulting in the sound of electric current.

Damaged speakers or speakers: If a speaker or speaker is damaged, they may squeak or make noises.

To solve this problem, you can try the following steps:

Confirm that the power cord is completely cut off: Check that the power cord of the speaker is completely cut off, making sure that they do not have any connection to the speaker.

Check the cables: Check if the speaker cables are loose or in poor contact. If there is a problem, reinsert the hoppers into them and make sure the connection is tight.

Check for damage to the speaker or speaker: Check for damage to the speaker or speaker, and if damage is found, it needs to be replaced or repaired.

If the above steps do not solve the problem of sharp tremor, it is recommended to contact a professional maintenance personnel for help.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can be consulted at any time to ask the car to ask the question, 24 hours ** answer.

If it is on the face of the car, then it is the fan sound of the radiator cooling the radiator, this is because the engine temperature of the car is too high, even after you stop, the fan of the radiator cooling is automatically temperature controlled, and when the water temperature drops to a safe temperature value, the fan will automatically stop working.

This is normal, but you should pay attention to the water temperature, especially at high speeds.

There are several reasons why speakers squeak:

The problem with the speaker itself,Maybe it's stupid because something in the speaker has been scraped or there is a resonance phenomenon。

The squeak of the speaker may also be a signal interference, and if the cable is not of good quality or the microphone cable is not in good contact, it will have this sound.

It is also possible that the volume potentiometer is in the dust and the contact is not good,If it is not very serious, you can rotate the speaker volume a few more times,If the silver withered fruit is more serious, it should be removed and cleaned with alcohol。
