Golf Rline, 1 4T, squeak

1. The engine has abnormal noise.

Symptom description: There is a lot of abnormal noise in the engine compartment, and most people also judge it to be the abnormal noise of the engine compartment by the sound**, which is usually a metal screeching sound or a howling sound.

Solution: The abnormal engine noise indicates that the technical status of a certain mechanism of the engine has changed. It is mainly caused by excessive wear and tear of some parts or improper assembly and adjustment.

Some abnormal noises can still predict that the engine will be damaged accidentally, so when the engine has abnormal noise, it should be repaired in time to prevent the fault from expanding.

It should be reminded that if it is an abnormal noise in the engine, most of the owners will not be able to solve it by themselves, and it is best to send it to the factory for maintenance.

2. There is abnormal noise in the gearbox.

Symptom description: If there is a "rustle" sound inside the gearbox while the car is driving, and there is no more after pressing the clutch or accelerator, there will be a whistle-like sound when changing gears.

Solution: There are many transmission parts, and the reasons for the sound are more complex, so we should pay attention to whether it is related to a specific speed, such as some planetary teeth that sound at about 50km h.

Whether it is related to certain gears, which is very important for judging the failure of the transmission, if a certain gear sounds, it must be related to the components that affect the transmission of the gear; If all gears sound, it is often a common meshing shaft failure or a lack of oil in the transmission. Whether it is related to specific actions, such as increasing and decreasing gears, starting, rapid acceleration, sharp deceleration, turning, etc., are effective means to judge abnormal noise, among them, changing speed and direction are particularly important for judging the rear axle fault.

If the abnormal noise of the transmission is obvious, it is recommended to send it to a professional repair shop to check the faulty parts, and then replace them.

3. There is abnormal sound of wear.

Symptom description: When driving on the accelerator or brake, there is always some abnormal noise in a certain part of the body, the sound is not loud, and it does not affect normal driving, but it always makes people worry a little about the failure of the body.

Solution: The abnormal noise of the door is mainly caused by the lack of lubrication, but it is necessary to judge whether it is the position of the door hinge or the glass regulator, door lock mechanism, handle mechanism, etc. inside the door. In the case of door hinges or limiters, special door hinges and slide grease can be used, while special door attachment grease is used for lubrication of glass regulators, door locking mechanisms, handle mechanisms, etc. inside the door.

In terms of brand selection, try to choose the commonly used brands in 4S stores, such as German Marty, Kluber, Tiger Head Hotolube, Fox, etc. It is not advisable to use engine oil or ordinary butter, it will freeze in winter, and the harmful smell will affect your health.

Product design, poor reliability, and poor technology of car companies will have this problem.

I'm still a little confused, can you be more detailed?

1.Causes of abnormal noise: In most cases, the Golf 44 generation 1...

8. Automatic squeak is caused by insufficient engine oil or poor oil quality. 2.Solution: Hit the vertical:

First of all, it should be checked whether the engine oil meets the specified oil volume, if not, the oil volume should be replenished in time; Secondly, the engine oil quality should be checked to meet the specified standards, and if the hail ignition does not meet the standard, the oil quality should be replaced in time. 3.Tips for a laughing adult:

It is recommended to check whether the engine oil meets the specified oil quantity and whether the oil quality meets the specified standards before each driving to avoid abnormal engine noise.

The reasons for the noise in the gear are improper operation, clutch failure, sprocket wear, and chain looseness.

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 were really faulty. 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 they lack their own understanding of mechanical knowledge, so they can distinguish the abnormal noise of the car and avoid wasting time and energy.

Second, the identification method of car noise:

In practice, due to the limitations of working conditions, it is difficult to use special instruments to measure the sound of the car, and the sound of the car can only be described and compared with the judgment of 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 make 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 sound. The normal vibration sound of each cluster system component (such as the noise on the engine surface), the impact sound of the gear when shifting, the air intake sound and exhaust sound of 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 loss of the grinding belt of the machine is not large, and there is no significant change for a long time, and this kind of fault can still maintain the normal driving 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 screw or other metal rod as a stestological instrument to contact the sound part to amplify the sound, or use a single cylinder fire off to reduce the sound, so as to meet the needs of this diagnosis. The auscultation site should be kept quiet to minimize interference from human factors.

There is a clicking sound in the gear shift of the golf gearbox, and there is a big guess in the driver's seat, how can the situation be solved? 4s says it's normal.? There is a click and abnormal sound in the gear shift of the golf gearbox, is there a rider who has such a situation, how can it be solved?

4s says it's normal.? It's only been 1 year, that's it, depressed, how long is the DSG warranty, 3 years, wow? If you want to change a word, you must be broken to change the structure of the dsg is decided, the front is very cool, after wearing, there will be some whimsical and the like Don't mind, go to the west, change one within the warranty It seems that it is a common problem only ......... timeCan't this be solved?

Shift gearbox? DSG is like this, oh oh, I'll go to 4S to see the specific reason, I guess there's nothing wrong with your car. Car maintenance is more complicated, and it is difficult to eliminate the occasional sound, but vice versa.

Oh, oh, when you enter the factory to report for repair, go directly to the 4S side to fill in the list or something, and after the gearbox is withdrawn, the click sound should be gone. If there is a clicking sound all the time while driving, then there must be a question and you need to enter the factory for repair. The sound is not all loud, but it's definitely not inaudible Today I saw that it was in 3rd gear which click sound has been going on all the time There is a sound in the upper gear is abnormal, and the sound from the downshift gearbox is normal, but it shouldn't be there every time, and the rolling and outgoing sound basically occurs under the condition of rapid deceleration.

Volkswagen DSG gearbox 2-3 frustration, the sound is normal, as long as there is no oil leakage, the problem should not be big. This is a flaw of Volkswagen that cannot be solved at the moment. At 23 gears, it is obvious that around 7080 depends on the speed of the mega gear, the sound that occurs in several gears, and whether it is an increase or a decrease in gear.

It depends: My Passat DQ380 gearbox 80 also sometimes makes a sound when decelerating sharply. May '16 car When is the car? @2019

First of all, the presence of common abnormal noises depends on the state of the engine's rpm.

Abnormal sounds are only present at idle or low speeds.

2) When the speed is maintained at a certain speed, the sound is disordered, and when the speed is rapidly reduced, a short sound is made one after another.

Abnormal noise occurs when the engine accelerates rapidly, and the noise persists when the engine is running at high speeds.

Second, the abnormal noise of the engine is obviously related to its load.

1) A cylinder is on fire, the sound is abnormal, there is no or decreased. The causes of noise are: piston striking the cylinder; Loose connecting rod; piston ring leakage; The piston is broken.

2) If the cylinder is closed, the sound will be aggravated, or there will be no sound, but there will be a sound at this time. The reasons for the noise are: loose piston pin copper sleeve; The piston skirt cone is too large; The piston jumped out; The connecting rod cover fixing bolt is loose, and even the connecting rod bearing alloy is burned and peeled off; The flywheel fixing bolts are too loose.

The abnormal noise caused by the misfire of two adjacent cylinders is reduced or eliminated. The cause of the noise is a loose crankshaft bearing.

3. The relationship between abnormal noise and temperature.

1) Low temperature sound, the sound weakens or even disappears when the temperature rises.

There is a sound when the temperature rises, and the sound decreases or disappears when the temperature drops.

4.Abnormal engine noise is often clearly related to the engine's duty cycle. Normally, the noise generated by clearances that are not related to the working cycle is mostly caused by the failure of engine accessories; If there is a constant metal friction sound from a part that is not related to the duty cycle, it can be considered that some rotating part is faulty.

Verb (abbreviation of verb) Relationship between abnormal noise and engine partsWhen the engine has abnormal noise, it is bound to produce a certain degree of vibration. Depending on the characteristics and location of the vibration, it can help diagnose the cause of abnormal noise.

Volkswagen Golf 7 low-speed driving squeak problem analysis.

1. The existence of common abnormal noises depends on the speed state of the engine.

The number of brigades and 1 squeaks only exist when operating at idle or low speeds.

2. The sound is disordered when maintaining a certain speed, and a brief sound is made successively when decelerating sharply.

3. Abnormal noise occurs when the engine accelerates sharply, and the sound still exists when maintaining high-speed operation.

Second, the abnormal noise of the engine has an obvious relationship with its load.

1. When a cylinder is fired, the abnormal sound is silent or reduced. The reasons for the sound are: piston knocking on the cylinder; Loose connecting rod bearings; piston ring leakage; The piston pin is broken.

2. When a cylinder is out of fire, the sound is aggravated, or there is no sound at the beginning, but there is a sound at this time. The reasons for the sound are: the piston pin copper sleeve is loose; The piston skirt cone is too large; piston pin out; The connecting rod bearing cover fixing bolt is too loose or even the connecting rod bearing alloy is burned and melted off; The flywheel retaining bolts are too loose.

3. The abnormal noise of the adjacent two cylinders is reduced or disappeared. The reason for the sound is that the crankshaft bearing is loose. Rough grip.

3. The relationship between abnormal noise and temperature.

1. The sound is low temperature, and the sound is reduced or even disappeared when the temperature rises.

2. There is a sound after the temperature rises, and the sound decreases or disappears when the temperature decreases. Yan Biqing.

Fourth, the abnormal noise fault of the engine often has an obvious relationship with the working cycle of the engine Usually, the noise caused by the gap unrelated to the working cycle is mostly faulty engine accessories; If there is a continuous metal friction sound emitted by a mechanical part that is not related to the duty cycle, it can be considered that some rotating part is faulty.

5. The relationship between abnormal noise and engine parts When abnormal noise occurs in the engine, a certain degree of vibration will inevitably occur, and the cause of abnormal noise can be assisted in diagnosing according to the characteristics and parts of vibration.
