What is the reason for the loud noise of the Volkswagen Tiguan engine

1. The reason for the loud noise of the Tiguan engine is: poor spark plug work; vacuum tube leakage; high-voltage line leakage; p Cv valve blocked; throttle position sensor failure; idling stepper motor failure; idling control valve failure; abnormal throttle opening; air intake system leakage.

2. The noise of the Volkswagen Touareg idling engine may be that the abnormal sound is generally more serious when the engine is hot, because when there is an abnormal sound, either there is a problem with the parts or a problem with the mechanism, which is not only troublesome to repair but also expensive.

3. You say too much. The reasons for the loud sound of the Volkswagen Touareg engine are as follows: Under normal circumstances, Volkswagen cars should be sealed or considered good. The sound of the engine is related to maintenance, such as the brand quality of the oil and the time interval of maintenance. If the oil condition does not deteriorate and there is nothing wrong with the engine, there will be no problem.

4. What is the reason for the loud noise of the SAIC Volkswagen Tiguan engine? SAIC Volkswagen Toguan (check the transaction price | detailed explanation of the model) What is the reason for the loud engine noise? The loud noise of the Tuguan engine may be that the belt is not elastic enough.

5. Hello, if the noise is relatively loud when the cold car starts, the engine sound will be normal after a while. This phenomenon is normal. The cold car idling engine speed is high, and the sound will be louder. I hope my answer can help you a little.

What should I do if the Volkswagen Touareg engine is loud and the new Luareg is noisy

1. The engine has a kicking sound, like the sound of a pencil hitting the table, and the sound increases when the engine speed increases. The possible cause is that there is dirt inside the engine. It is recommended to change the oil, filter and wash the engine. Others may be valve problems.

2. Noise reduction is mainly handled by adding sound-absorbing materials or soundproofing materials.

3. Abnormal sound of the engine compartment. The screw of the under-engine guard is loose, causing the engine to be unstable, and it will shake violently and produce noise when working. This is a common malfunction. You only need to tighten or adjust the screw of the under-engine guard; in addition, the claw tape fixing the engine is aging, and the claw pad plays a role in supporting the engine.

4. The vehicle engine is a source of noise. Some advanced sound-absorbing foam materials can be installed on the engine cover to suppress the vibration caused by the hood. Soundproofing materials can also be pasted on firewall stickers and door panels to isolate noise.

Volkswagen SpeedWhat is the reason for the loud noise of the Teng engine?

1. The reasons for the loud noise of the Volkswagen Swift engine are as follows: 1. It is not suitable for the viscosity of the new oil. After long-term use, the oil will become thinner and thinner, and more and more carbon will accumulate. After replacing the new oil, the engine cannot adapt to the viscosity of the oil, which may increase the speed, thus causing engine noise; the sound insulation effect is poor, and the seal of the car needs to be checked.

2. The reasons for the loud noise of the Volkswagen Swift engine are as follows: there is a serious carbon accumulation in the engine. Coolant, under low temperature conditions, if the coolant is insufficient, the noise of the engine will become louder, and the coolant of the car needs to be checked in time. The screws on the under-engine guard are loose.

3. Analysis of the specific reasons for the loud engine noise: 1. Step on the accelerator and find that the acceleration is not obvious, lacks power, and the engine has a hysterical sound.The most likely time to happen is when the engine is hot, or cold, or when there is a shortage of oil.

What is the cause of the loud noise of the Volkswagen Polaroid engine

1. The reasons for the loud noise of the Polaroid engine are as follows: 1. It is not suitable for the viscosity of the new oil. After long-term use, the oil will become thinner and thinner, and more and more carbon will accumulate.

2. The possible reason is dust in the engine. It is recommended to change the oil, filter the engine and clean the engine. There may also be a valve problem; there may be no problem with driving, and there will be a clicking sound when accelerating. It is recommended to check the ignition time setting. It may be that the engine is overheated, the engine has carbon accumulation, and the oil is not good, and high-grade oil needs to be added.

3. The main reasons for the loud sound of Volkswagen's engine are as follows: there will be a clicking sound when the engine is idling, as if something is knocking on the metal. Although it may not be heard during acceleration or driving, it is likely to be caused by a cylinder valve. At this time, you can adjust the valve to solve it.

4. Analysis of the specific reasons for the loud engine noise: 1. Step on the accelerator and find that the acceleration is not obvious, lacks power, and the engine has a hysterical sound. The most likely time to happen is when the engine is hot, or cold, or when there is a shortage of oil.

5. The reason for the loud noise of the car engine: Reason 1: the foot glue is aging or loose; the foot glue is the rubber block cushioned between the engine and the frame. Its function is to reduce the vibration and buffering of the engine during work, and to fix the engine.

6. There may also be a problem with the ignition time setting, which will also lead to such symptoms. As for others, it may be an internal problem with the engine, such as EGR valve blockage. When accelerating, the engine makes a hissing sound, or when it slows down, it also appears. In short, it changes with the RPM and the volume changes.

What to do if the engine of Volkswagen Touareg is loud

The engine has a kicking sound, like the sound of a pencil knocking on the table, and the sound increases when the engine speed increases. The possible cause is that there is dirt inside the engine. It is recommended to change the oil, filter and wash the engine. Others may be valve problems.

The solution is to remove the soundproof cotton first, and the originalIt's hotted up. After removing it, glue all the areas where the foam glue can stick, and put a circle on the soundproof cotton. Put the soundproof cotton on it. When we find some screws and washers at home, we will fix it with screws.

This is a relatively common small fault. Just tighten or adjust the engine lower guard screw; another type is the aging of the glue strip of the engine fixing claw machine, and the claw pad plays a role in supporting the engine. When it ages, it cannot perform normal work. At this time, it cannot be repaired, and a new machine can only be replaced. Claw pad.

The FAW Volkswagen engine is very noisy. What is the reason?

As for others, it may be internal problems of the engine, such as EGR valve blockage. 3. LaunchThere is a hissing sound, just like steam or air coming out of the engine. Generally, after hearing this sound, the engine will quickly lose power. There may be a problem. The engine is overheated. Check the cooling system.

The possible reason is dust in the engine. It is recommended to change the oil, filter the engine and clean the engine. There may also be a valve problem; there may be no problem with driving, and there will be a clicking sound when accelerating. It is recommended to check the ignition time setting. It may be that the engine is overheated, the engine has carbon accumulation, and the oil is not good, and high-grade oil needs to be added.

The common reasons for the abnormal sound of the car engine are as follows: the engine knocks on the cylinder. The phenomenon is that the engine makes a strange sound of "dang-dang". The engine knocks on the cylinder, mainly because of the sound produced by the impact of the piston skirt and the cylinder wall when the engine is running.It is generally due to poor lubrication conditions. The solution is generally to replace the four accessories of the engine.

The reason for the sound of the Langyi engine may be engine vibration. There is a fixed soundproof cotton under the engine decorative cover. The gap is large and loose. There is a collision sound on the hard edge of the soundproof cotton edge, which is the problem and the abnormal sound from the engine resonance.
