I now own a 2016 M Sports 520d Alpine White and am glad to be back with BMW after a three-year absence (BMW Premium Selection 15000KM). Up until I start looking at the ASD, I’m extremely content with the automobile and don’t believe I was missing anything. I can see several ASD options when I select the HU NBT option (ASD configuration, ASD OFF, etc.), but the only sound I hear is the regular engine noise.

What does ASD in a BMW mean?
In order to alter the interior and outside noise of the car, active sound design (ASD) uses inputs from the engine and vehicle speed, pedal input, exhaust noise, and vehicle vibrations. The desired outputs are produced by filtering these input variables. ASD variants choose one or more of these factors to implement a new sound. Among these variances are:
- Signals that are communicated in the vehicle’s interior directly from the engine output are known as passive sound generation.
- Increasing the exhaust input and producing a new output to increase the vehicle’s outside noise are examples of passive and active sound creation.
- Active mounts: providing vibration outputs to the interior of the car while accepting inputs from the exterior of the vehicle.
- Synthetic audio: creating a brand-new sound using the internal stereo system.
What BMWs feature ASD?
The greatest place to start looking for Active Sound Design in a car is the BMW model type. The BMW M240i and BMW M235i are two M performance vehicles that are most frequently affected by fake engine noise. Nowadays, automotive sound simulators are nearly standard equipment on all contemporary BMWs with a performance focus. For instance, the BMW i8, BMW M5 F10, BMW X3 M40i, BMW X4 M40i, or BMW X6 50i SUVs all come standard with ASD.
How do I deactivate my BMW ASD?
Simply give it a longer drive after deactivating ASD with Bimmercode, and it should activate again. The best way to turn off active sound is to unplug a wire or other component from the amplifier, but doing so is difficult. Bimmercode is much simpler to use.
ASD engine: what is it?
Modern vehicles have complex fuel and ignition systems built into the electronic engine management systems that work together to make the car run. Both systems have a number of parts that work together to give the engine timed fuel and ignition.
The automated shutdown relay, often known as the ASD relay, is one of these parts. The ASD relay is in charge of giving the vehicle’s injectors and ignition coils switching 12-volt power so they can deliver gasoline and generate spark.
The oxygen sensor heater circuit for the car may also receive power from the ASD relay in some circumstances. The ASD relay also serves as an automatic shut-off switch that turns off the fuel and ignition systems when the computer senses that the engine is no longer running. The ASD relay, like the majority of electrical parts, is subject to the regular wear and tear that comes with normal service life, and when it malfunctions, the entire vehicle may have issues. Usually, when the ASD relay has malfunctioned or failed, the car may exhibit a few indications that can notify the driver that a problem has arisen and has to be fixed.

Are there adaptive cruise controls on every BMW?
Despite not being designated as such, Adaptive Cruise Control (ACC) systems are frequently included in contemporary BMW models. Search for the phrases Active Cruise Control and Dynamic Cruise Control instead.
Dynamic Cruise Control is a relatively straightforward improvement over conventional cruise control. It is adept at maintaining a particular speed and deploying the brakes when necessary. This indicates that it doesn’t quite qualify as an ACC system.
On the other hand, Active Cruise Control is an adaptive system in all but name. The ability to select and maintain a distance behind other vehicles is one of many enhancements made to a standard system by the Active Cruise Control supplied by BMW.
Let’s examine some of the factors that make drivers adore adaptive cruise control:
If you intend to purchase a brand-new BMW, your auto insurance costs may be quite high. A few minutes and hundreds of dollars can be saved on your insurance by using Jerry, a comparison software. Jerry customers typically save over $800 a year on their insurance.

How does BMW Active Sound work?
“Active Sound Design” is a feature that is standard on the majority of new BMW models. It is essentially the sound of your car’s engine being amplified and fed via the speakers within the cabin. It was first introduced on F10 vehicles. According to BMW, this was a required feature because modern vehicles are so well-sound-insulated that the engine can hardly be heard at all. Additionally, the sound coming from the back of your automobile isn’t really helpful because laws require quieter exhaust systems.
BMW had to take action in order to maintain the aural experience or keep it as close to the genuine deal as possible, despite some BMW enthusiasts’ complaints about the way things are done. The Active Sound Design function wasn’t always as “efficient” and “accurate” as it is now. The sound didn’t exactly like the genuine thing; it had a deep, artificial vibe to it. It was unsettling when, for example, some straight-six engines would sound like V8s.
They have improved in recent years, and the video below demonstrates how you can even change the ASD settings by using a sub-menu in the infotainment system. You must access the “Car” menu, scroll all the way down to “General Settings,” select “Engine Sound,” and then alter the sound’s volume. Depending on the driving mode, the car will by default modify the Active Sound Design level. Basically, the sound will change anytime you switch to Sport mode if you don’t fiddle with these settings while driving.
If you don’t like that, you can change the settings manually. Active Sound Design is always available in Sporty mode. Depending on your desire, it can also be Balanced or Reduced. Now move along and configure your car as you choose.
Can I upgrade my BMW to get adaptive cruise control?
I was considering the BMW’s adaptive cruise control option, but I’m not sure if I really need it. If I don’t receive it before I buy the car, can I add it later?
A useful feature is adaptive cruise control, especially if you travel long distances at high speeds. After purchase, you can add adaptive cruise control to your BMW, but it won’t be the same system that comes pre-installed in BMWs. Additional adjustments or alterations to the vehicle’s system might be necessary.
Without factoring in installation, you should expect to pay between $2,000 and $2,500 for the system alone. This is for the best system available, which operates at speeds between 60 mph and a complete stop.
The good news is that most BMWs already feature adaptive cruise control, so you won’t need to worry about purchasing it separately. Leave the function inactive if it’s one you don’t wish to use.
While having adaptive cruise control is helpful when driving for a long distance, you should also make sure you have a reliable insurance policy to keep you covered. You can find the best quotes from more than 55 major insurers in less than 45 seconds with Jerry, the number one auto insurance super app. Simply download the app, provide some information, and Jerry will find you discounts on the ideal coverage.
Has the BMW X5 active sound?
BMW vehicles’ Active Sound is scarcely news these days. The trend began years ago and is still going strong in the newest models. We thus spoke with BMW engineers about the sound of the new power SUVs during the international media presentation of the BMW X5 M and X6 M.
Axel Theiling, head of powertrain for the X5M and X6M, asserts that it is crucial for BMW to provide each M model a distinctive sound signature. The sound of the X5 M and X6 M is first noticeably different from the earlier M5 Competition or the more recent M8 Competition models, as captured on film by us.
The new X5 M and X6 M do, of course, include an Active Sound component. According to Theiling, this is employed to mask the sound notes created as a result of complying with noise emission regulations.
Additionally, according to Theiling, the new noise regulations in Europe are preventing automakers from truly providing the loud, deep tones that consumers expect from a high-performance vehicle. The drive-by noise rules, which are becoming common in Europe, are among the acoustic emissions.
As a result, it is becoming increasingly difficult to comply with requirements if the exhaust sound only comes through the exhaust system. Another aspect of the noise compliance rules is tire noise.
This places BMW and other automakers at a crossroads because such standards frequently conflict with what real customers want from their vehicles. When most vehicles are electrified within the next ten years, this won’t be much of a problem, but for the time being, let’s enjoy the last reasonably sounding vehicles.
What location is the ASD relay?
- The battery voltage is first connected to terminal number 30. Note that the automated shutdown relay and the gasoline pump are both permanently wired to terminal 30 of the battery.
- Through terminal 85, the Powertrain Control Module grounds the ASD relay from the side of the coil.
- Terminal 86 supplies voltage to the coil side of the ASD relay.
- The fuel pump and ASD relay are turned off by the powertrain control module. In the off position, terminal 87A is connected to terminal 30.
- The remainder of the circuit is not receiving power.
- Terminal 30 is wired to terminal 87 in the on state when the powertrain control module (PCM) is operating the fuel pump and automatic shutdown relay. The terminal with number 87 is responsible for supplying voltage to the remaining portion of the circuit.

The automatic shutdown relay also activates when the vehicle’s engine first starts up and runs, giving switched power of 12+ volts to the fuel injectors and ignition coil. This aids in the engine system’s smooth operation.
In order to protect other engine parts and the entire vehicle, the ASD relay promptly stops all of its operations when the engine of the vehicle is turned off. The oxygen sensor heater relay and sensor heating elements of the car are powered by the ASD relay using some emission packages at 12+ volts.
The power control module regulates the operation of the circuit that makes up the ASD relay, so when it turns the circuit on or off, it also initiates or terminates the operation of the automatic shutdown relay. The primary purpose of the ASD is to supply 12+ volt electricity to the ignition coil, oxygen sensor heater, injectors, and O2 sensor heater components in the car.
