The BMW engine is abnormal, and the BMW 5 series engine is abnormal

Aerodynamic squeak is mainly caused by the vibration of the air flow in the intake, exhaust and running fans of the engine. Squeak and squeak are related to engine speed, temperature, load and lubrication conditions.

Therefore, in order to accurately determine the cause of abnormal engine noise, it is necessary to conduct a professional inspection of the car. In addition, the situation varies depending on the model.

If the engine sound is slightly louder every time it reaches 1500 rpm, and it is normal to reach this value or exceed this value, it may be that there is something wrong with the engine's holding system. You can try to adjust the ignition time first.

Your car is burning engine oil, or leaking oil, you first look at whether there is a leakage of engine oil, if not, then you are ready to change the car, burn the engine oil to open the cylinder to see how many cylinders burn, and the imported X3 engine unit is tightly arranged, the general place will not open the cylinder for you, afraid of damage! I hope you're just leaking oil in the same situation as I was back then!

If there is no warranty period, hurry up to repair, I don't know if your car burns oil obviously, the choice of engine overhaul should not be as terrible as imagined, an old engine to take, wear and tear places are replaced, just like new.

When there is a problem, go to the 4S computer to check the fault code, if not, you don't have to go to 4S, a good repair shop may still solve the big problem.

Check if there is any oil leakage, such as the valve chamber cover, the oil seal after the curvature, if not, it will have to be overhauled.

Summary. The engine has a sound in this case, it is necessary to check the valves in the engine, including the piston in the engine, including the piston ring, including the belt of the engine, and the belt tensioner of the engine. This needs to be checked specifically, that is, it feels that the sound is relatively loud and that it is the engine of the same model and the same model.

It is that if you feel that the sound is relatively loud, it is a problem, this is a specific inspection, these aspects, if the sound is the same after comparing with the engine of the same model and the same model, it is a normal phenomenon, BMW 5 series this car, the sound of this engine is relatively large, especially after the cold car starts, the noise of the engine is relatively large.

BMW 5 Series engine noise.

Hello, I'm helping you sort out the answers to your questions, please wait a moment

The engine has a sound in this case, it is necessary to check the valves in the engine, including the piston in the engine, including the piston ring, including the belt of the engine, and the belt tensioner of the engine. This needs to be checked specifically, that is, it feels that the sound is relatively loud and that it is the engine of the same model and the same model. It is that if you feel that the sound is relatively loud, it is a problem, this is a specific inspection, these aspects, if the sound is the same after comparing with the engine of the same model and the same model, it is a normal phenomenon, BMW 5 series this car, the sound of this engine is relatively large, especially after the cold car starts, the noise of the engine is relatively large.

At idling, there is that kind of buzzing at intervals, and the sound is getting louder and louder.

The intervals are short and the sound is not continuous.

If this kind of sound is like a sound from a cooling fan, this is normal. If the cooling fan is not turning, this sound appears. In this case, it may be the sound of the canister or the solenoid valve of the canister, or the solenoid valve of the exhaust gas.

This is also normal.

It is necessary to check the cooling fan when this sound appears, if you rotate this, it is normal, there is no problem, including this carbon canister solenoid valve, including the exhaust gas solenoid valve, this is also a normal phenomenon.

Summary. Hello, happy to answer your questions.

As soon as the BMW starts, a chime sounds.

Hello, happy to answer your questions.

As soon as the BMW starts, a chime sounds.

As soon as the BMW starts, a prompt sounds, do you mean the instrument prompt or your navigation system prompt? In this case, the BMW will sound as soon as it starts, and I remember that BMW has this kind of sound, and as soon as I start the car, there is a sound.

Gauge Prompt But there are no fault display signs.

Personally, I think this is a normal phenomenon, because I have driven a BMW before and have this kind of sound, if you don't believe it, you can make a comparison, if it is. If you really feel uncomfortable, it is recommended to go to the BMW 4S store to check it.

Ok thanks.

Okay, you're welcome, but if you feel really uncomfortable, you can go to the BMW 4S store to check it out. Tell the BMW 4S shopkeeper that I'll try it out with the same car.

There are many kinds of abnormal noises, including abnormal noises inside the engine, abnormal noises of pulleys outside the engine, rotating parts and suspensions, etc., all of which will be generated. It is recommended to go to a 4S shop or repair shop for a comprehensive inspection.

1.No matter what "abnormal noise" there is, it is the premise to find the problem and repair it in time without delay.

2.According to the results of the inspection, the relevant faulty parts or the personnel reasons of missing, reverse installation and unfastening, timely treatment, repair and fixation. Eliminate potential safety hazards.

3.It is recommended that the special car be repaired, directly sent to the after-sales service for maintenance, and if the problem is found, the after-sales maintenance can protect the original parts, and the second is to ensure the after-sales service.

4.If you can't find a solution or repair point when you find a problem, you can take out the user manual (with the car) and refer to the nearest service station.

The interior strip is abnormal, and the air conditioner crackles too cheaply, this needs to remove the central control interior strip, wrap the buckle with suede tape, and lubricate all parts on the interior strip with lubricant. This is the manufacturer's reply method, which is troublesome. The door is easy to do, the door interior strip buckle lubricant, press repeatedly to make sure there is no abnormal noise.

There is also the co-pilot's abnormal noise, the co-pilot squeaks as soon as he crosses the bumpy road, how to get it, who solves the problem, BMW Brilliance quality control is really drunk.

1. Engine oil reason.

The oil cause does cause the engine to sound different when it is working. Some friends found that the sound of the car seemed to have become louder after the first insurance, which was due to the fact that the new car had just left the factory, and the engine oil in it was the initial engine oil added by the manufacturer before the first insurance. Unlike the engine oil we buy outside, the initial engine oil should be suitable for the operation of the new car engine.

The various parts in the engine of the new car can not be completely run together due to processing errors, processing technology and other reasons, and the internal running resistance is large, so it is necessary to have low viscosity and good heat dissipation of the initial oil, but the requirements for the cleanliness and oxidation resistance (anti-rust) of the engine oil are not so high. Moreover, in order to speed up the running-in, some of the initial engine oil is also mixed with abrasives to accelerate the running-in of various friction parts inside the engine. Therefore, when the initial engine oil is replaced at the time of the first insurance, the viscosity of the engine oil becomes larger, the formula is also different, and the sound of the engine running will indeed become louder.

2. Carbon deposition increases.

Carbon deposition is an inevitable phenomenon of the car, and after a long time, the engine will not only lose power and increase fuel consumption, but also have the problem of louder noise. In the process of working in the engine, there will always be some impurities in the gasoline that will become carbon deposits at high temperature and high pressure and remain in the engine, even if the quality of the gasoline is very good, there are some long-chain hydrocarbons inside itself, the combustion speed is slow, the combustion is incomplete and becomes carbon deposits, it can be said that carbon deposits are unavoidable. All we can do is to try to develop good driving habits and maintain them in time to reduce carbon deposits.

If the maintenance is not in place or the driving habits are poor, the carbon deposition in the engine will be more serious after a long time.

3. The engine mount is aging.

Problems with the engine mount also lead to louder noise, which can also bring additional jitter, resonance, and other problems. The engine is anchored in the engine compartment by several feet that are designed to hold the engine in place. When the engine is running at high speed, it is inevitable that there will be shaking, so these feet have rubber pads for absorbing shake and cushioning to prevent jitter from being transmitted to the car body and causing undesirable resonance and noise.

4. Aging of sound insulation adhesive strips.

Even if the oil is added in full accordance with the normal standard, the car will be used for a long time, and the sound will indeed become louder in the car, the main reason is that the sound insulation of the whole vehicle has deteriorated.

Not only BMW, when the engine of our car is too loud, we need to focus on the following aspects to avoid irreparable accidents:

1. When the car is idling, when the front cover is opened, the car engine has an abnormal sound, if you can't hear this sound in the car, it is not too big, generally the sound of the valve or fuel injector.

2. The carbon canister solenoid valve also has this sound, but the sound is brittle. There is a way to distinguish, that is, to give a little oil at idle speed to see if the frequency changes, if the frequency does not change, it is the sound of the solenoid valve, if the frequency changes, it should be abnormal noise at the valve. If you can't hear it clearly in the car, the problem is not big, and the vehicle will have a corresponding clicking sound, one is the sound of the fuel injector working, and the other is the valve part;

3. There is a similar sound, which is the sound of a timing chain, but it is different from the sound of a clatter, there is a sound of Gragra.

4. When the car starts cold, the engine sound will be slightly louder than that of the hot car, as long as the sound sounds uniform and soft, not harsh, there is generally no problem. This is due to the fact that the gap between the cylinder wall and the piston is not yet optimally sized during cold driving, and the lubrication of the oil is not sufficient. Usually when the engine block temperature reaches about 95 degrees, the sound will return to normal.

5. The reason for the engine oil. Inferior engine oil or not changing the engine oil for a long time, lack of engine oil, etc., can easily lead to increased friction between the valve and the duct and the hydraulic tappet, etc., so that the various sounds in the engine are louder.

If you are still not at ease after the above investigation, it is recommended to go to the nearest auto repair shop to confirm the cause of the failure, which is the safest method.

The reasons for the high noise of the BMW engine are:

1. Carbon deposition increases.

2. Engine mount aging.

3. Aging of sound insulation adhesive strips.

4. The oil pump, cooling ruler slow meditation system and exhaust pipe are ruptured.

5. Poor fuel quality.

An engine is a type of energy that is capable of converting other forms of energy into mechanical energy.

, which applies both to the power generation unit and to the entire machine including the power plant.

Take the BMW X1 as an example: its length, width and height are 4565mm, 1821mm, and 1620mm, the wheelbase is 2780mm, and it is equipped with a 7-speed dual-clutch transmission.

The car has a fuel tank capacity of 61 liters, a maximum horsepower of 140 hp, and a maximum speed of 195 km/h.

Technical features: 1. The valve drive mechanism of the engine adopts the hydraulic support ball rocker arm structure, which is the same as that of the current general gasoline engine.

Compared with the hydraulic tappet valve actuation mechanism commonly used, this novel air pellet valve actuation mechanism has the advantage of relatively small friction torque, so the required driving force is also small, so that the engine power consumption can be effectively reduced, and fuel consumption can be reduced.

2. In order to effectively reduce the weight of the whole vehicle, the liter gasoline engine adopts aluminum alloy cylinder block, which has achieved a very obvious lightweight effect.

3. The use of special materials and plastic intake pipes processed by special technology instead of traditional metal intake pipes not only receives lightweight effects, but also can effectively reduce the resistance of the intake pipe wall, improve the intake efficiency, and increase the engine power.

The abnormal engine noise of the BMW engine is caused by idling, idling and clicking of the cold car, and the sound decreases a lot or disappears after the car is warmed. Here's how to fix the BMW engine click: Idling:

It doesn't matter if the car is hot or cold, there are no steps, as long as it is idling, there will be a clicking sound, which can be heard inside and outside the car. This is the case for BMW models.

The abnormal engine noise of the BMW engine is caused by idling, idling and clicking of the cold car, and the sound decreases a lot or disappears after the car is warmed. Here's how to fix the BMW engine click:

Idling: Regardless of whether the car is hot or cold, there are no steps, as long as it is idling, there will be a clicking sound, which can be heard inside and outside the car. For BMW models, one of the common reasons for this is the vibration of the high-pressure oil rail, which can generally be solved by replacing the high-pressure oil rail with a shock absorbing pad.

There is a clicking sound when the cold car idles:

In this case, it is usually the problem with the hydraulic tappet (HVA). If this clicking sound only occurs occasionally, it may just be caused by short distance driving at extremely low temperatures, and the lack of oil supply to the hydraulic tappet, which can be solved by long-distance driving. If the clicking sound is frequent, the hydraulic tappet should be replaced.

Is it normal for a BMW engine temperature to be around 120?

The BMW engine temperature is abnormal around 120, and the BMW engine water temperature is normal at 95-105. If the temperature exceeds 105, the water temperature will be high, so check the antifreeze, thermostat, cooling fan, water temperature sensor, water tank, water pump.

Cause: The high water temperature is caused by insufficient coolant, malfunctioning cooling fan, and malfunctioning circulating water pump.

Normal temperature: The water temperature of the car reflects the working condition of the car's cooling system. The engine must work well at the right high temperatures. Generally speaking, the engine is at its best when the engine coolant temperature is around 90 degrees.

At this temperature, the combustion chamber is hot enough for the fuel to evaporate completely, so the fuel can be burned better and gas emissions can be reduced.
