Why Does My BMW Sound Like A Diesel?

beginner drivers

The N20 engine typically exhibits some diesel-like clatter at idle, especially at cold starts. Your description, meanwhile, gives the impression that the clatter’s volume has risen. That merits examination in and of itself.

I also own a 2013 and have driven loaner 2014 and 15s, so I can attest to the fact that they are distinct from one another. First off, the 2015’s speakers are used to pump in engine noise. From the inside, the engine now sounds more like a six cylinder. All you hear in the 2013 is that little little 2.0 4 cyl because it lacks such fake sound augmentation. I think they sound similar when heard from a distance. When you activate the auto-start-stop feature on the 2015, you can hear a slight improvement in the smoothness of the sound. The 2013 auto-start shakes the car a tiny bit and is a touch unpleasant. The 2015 auto-start is more smoother when it operates. I believe that as the years passed, the engine was simply refined.

Seriously, it’s the noise DI engines make; quit whining about it and take use of the system’s increased power and better fuel efficiency instead. In any case, you can only truly hear it while it is idle.

For a long time, I believed my 2013 was a diesel. I suppose I should begin using standard gas.

Our E90 models 330 and 325 will also get a boost soon. So in my opinion, there is really a better chance of getting more horsepower out of a 330 than a 335.

That would definitely be a threadjack, I’m afraid. LOL Although I believe the primary query was addressed.

Both of them have flaws, albeit in different ways. The S3 has far better suspension and a firmer chassis, but the turbo lag makes cornering difficult and stop-and-go traffic excruciating.

The S4’s SC’d V6 delivers power quickly (like snap your neck power), and there’s more of it than before. However, there’s also more car, weighing in at 4000 pounds. Cornering is enjoyable for enthusiastic driving, but if you push it, the nose-heavy oversteer rears its ugly head. Easily controlled but still feels “sloppy” in comparison to the S3.

The S4 replaced a Q5, and the S3 replaced a Stg 2 Mk6 GTI, and I still smile whenever I drive either one. Suffice it to say, I’m waiting for my lease to expire and hoping the TTRS will arrive and meet my demands.

BMW’s DI approach does indeed sound diesel-like. The OP hears a difference between his 2013 and his wife’s 2015, but post #6 does not clarify why. Additionally, it doesn’t explain why his car is beginning to sound more and more like a diesel.

Whether or not there is a problem with the revised timing chain is something I’m actually curious about. Or perhaps a software update is the cause.

What differences are you noticing, OP, within the car or outside with the hood open? As previously stated, the active sound design of the 2015 vehicle may be to blame for the interior.

Yes, I would choose the 6-cylinder if you given me the choice between a 6-speed 328 MSport and a 6-speed 335 MSport.

There you have it, now go out and get one, you know it makes sense, the difference is 2 extra cylinders and a whole bunch of stuff to make you drive faster and stop quicker.

MTA Los Angeles, hahaha The MTA now operates 2,221 compressed natural gas-powered buses in addition to one electric bus and six gasoline-electric hybrids. Since there are no diesel buses, that can’t be the issue.

I haven’t been able to post frequently since I received my 335d because I’ve been so busy with work and other things.

I think my engine tone has altered after I reached two thousand miles; it is not as loud as a truck, but it is audible. I also noticed a slight rumble. when I wake up in the morning and when my windows are closed. But since there are so many loud, black-smoke-blowing diesel vehicles in Spain and around Europe, I don’t really consider it to be a problem.

not retching too much. If you look up “wastegate rattling,” you’ll find other folks who are experiencing the same issues.

Funny how I always remark my 335i sounds like a diesel when talking about noise issues. It began with a deep rumbling that resembled a modified exhaust sound. However, it lately began making rattling noises. Both the shop foreman and the service advisor claim it is typical.

BMWNA made a lemon buyback offer, however they are citing my frequent HPFP fixes as justification for my eligibility. It sounds like the diagnosis and repair will be very expensive and/or difficult.

As a result, whenever I stop at a red light, my automobile makes a noise that is somewhat reminiscent of a diesel truck. Should I be concerned or am I behaving too quickly?

Is that a 328i? possible lifters’ ticking noise My vehicle made a diesel-like noise, therefore the lifters were changed. If the issue persists, the head will be changed. Take a video of it and present it to your SA if it only occasionally does it.

Why does my car sound like a diesel all of a sudden?

My 1999 Nadia has excellent speed and performance, but its noise from the engine is a concern. It has a petrol engine but drives like a diesel vehicle. What could my engine be having issues with? Additionally, there is an issue with the ignition. I assumed it was because I hit a speed bump, but I have yet to find the appropriate fuel pump for it. I kindly ask for your assistance. Solomon.

Your worry about the new noise coming from your car’s engine is valid. When something is wrong, cars communicate just like people do. All automobiles create some sort of noise, which is indicative of their operation and is recognizable to the driver.

A simple misfire or costly wear and tear of the swiftly moving metallic components may be to blame when an automobile engine starts to make an unusual noise. Your petrol engine makes the sort of rattling noise that a diesel engine makes.

Why does my BMW make an airplane sound?

A leak in the exhaust system is another typical reason why your automobile may sound like an airplane or helicopter while you’re driving. Your car’s exhaust system is designed to transport dangerous pollutants from the engine through a secure system and outside of it. Your exhaust system may become cracked or leaky, which could result in increased noise while driving. It is recommended to trust an expert with any necessary exhaust repairs because finding leaks can be challenging.

Why is the engine in my BMW so loud?

Incorrect data can be sent by a malfunctioning or dirty sensor, which could cause the engine to get too much or too little gasoline. This may cause the engine to run poorly and sound louder than usual. Spark plugs that are bad or dirty might cause the engine to misfire, which will make the car run louder.

What is the whining noise coming from my BMW?

You can definitely blame the power steering system if you specifically hear a whining noise everytime you turn the steering wheel. A loose belt is one thing that can have happened to generate this annoying sound. Additionally, excessive friction from a leak in the power steering system can result in this sound. It’s preferable to have a professional check out and fix your power steering system in any case.

How can I improve the sound of my BMW?

  • Get a more compact muffler. The smaller your muffler, the louder your automobile will be because they are made with loudness in mind.
  • Place a specialist exhaust assembly in place. The most straightforward approach to increase your engine volume is to modify your exhaust system.
  • Purchase a bigger downpipe. These increase the volume of your car by lowering the exhaust’s backpressure.
  • Your exhaust system’s resonator has to be removed. This alters the tone of your car, causing it to make deeper sounds.

Just keep in mind that some counties and states have restrictions on how loud your car can be. Check your local laws such before making any alterations to your vehicle.

How do I quiet down my BMW engine?

Fortunately, BMW gave you a few options. If your car has a sound simulator, you can vary the volume of the sound by adjusting the ASD settings in the iDrive menu. You can choose to have it reduced, balanced, sporty, or applied to the driving mode, depending on your preferences.

The NBT Evo ID5 and ID6 head units’ ASD can be altered as follows:

  • Enter the “Car” menu.
  • Go to “Settings.”
  • Decide on “General Settings.”
  • To find “Engine Sound,” scroll down.
  • Select your preferred driving mode from reduced, balanced, sporty, or other.

What causes the buzzing sound my BMW makes when I accelerate?

The “humming” you may hear and feel on the steering wheel is caused by the engine creating energy that cannot be transferred to the wheels and instead becomes heat and vibration.

Why is my engine making a whining noise?

It may signify the same thing if you hear a whining noise coming from the engine of your car: there is a worn-out component. Hearing a whining sound indicates that it’s time to book a service appointment because if these parts break or wear out completely, they could cause damage.

What causes diesel knock?

Diesel engines produce a clanging, rattling sound when they are running, known as “diesel knock.” The compression of the air in the cylinders and the ignition of the gasoline when it is fed into the cylinder are what are making this noise. This is very similar to a gasoline engine that exhibits spark knocking or pre-ignition. To avoid part damage, which can happen as a result of heavy knock, the timing of the fuel injection into the diesel engine is essential.

Compared to its gasoline equivalent, a diesel engine operates differently. In a gasoline engine, the mixture of fuel and air is compressed before being ignited by an electric spark. One and only the air is compressed in a diesel engine. After injecting the fuel, the cylinder is heated by the compressed air, which ignites the gasoline naturally without the use of an electric ignition.

The process of fuel injection contributes to the distinctive sound of a diesel engine in operation. The fuel ignites when it is injected into highly hot compressed air while the piston is still moving up in the cylinder, resulting in a detonation and consequent rattling sound. The process is compression-driven, and the more compressed the cylinder is, the more power the engine produces.

On the street, gasoline engines normally run at compression ratios of 8:1 to 10:1, whereas diesel engines typically run at 14:1 to 25:1. A diesel engine may function much more effectively than its gasoline counterpart thanks to its higher compression ratio. Diesel knock is an acceptable outcome of the ignition process and is a by-product of the increased compression and fuel injection process.

Because a diesel engine does not have an electronic ignition system, it is challenging to start one in cold weather. Glow plugs are frequently included by manufacturers in diesel engines as a starting help in cold areas. A wire coil in the combustion chambers of a glow plug is heated to a red-hot temperature by the battery. Up until the engine reaches operating temperature, this makes the diesel knock in the engine more noticeable. As the fuel inside the engine starts to ignite more easily, knocking decreases.

Special engine mounts have been developed by several manufacturers to reduce passenger-side diesel knock. Due to their higher fuel efficiency, diesel engines are being used in more and more passenger cars as gas prices rise. Many people consider knock to be a bearable side effect of increased fuel efficiency.
