Its aim is to track the concentrations of oxidizable gases in the air stream passing through the radiator. It is fixed on the side of the radiator shroud (frequently the mounting breaks). The fresh air flaps open once the noxious levels drop, but not for more than three minutes when heating or twelve minutes when cooling, after a predetermined threshold value for the level of gasses is exceeded. These time restrictions are included into the system to stop fogging.

An additional element that regulates the automated operation of recirculated air is called automatic recirculated air control (AUC). The AUC feature makes use of an oxidizable gas sensor that is often located behind the radiator’s right side or on the right side of the fan shroud (samples air quality as coolant fan pulls across the radiator). The IHKA module-powered heating element and a gas sensor are both incorporated in the AUC sensor. Heating is necessary for the gas sensor to function properly. Based on the quality of the air, the sensor generates a changing voltage (concentration of hydrocarbons, NOX, SOX, and CO). As the air becomes increasingly contaminated, the voltage rises. The IHKA closes the fresh air flaps once it reaches a predetermined value. The system features built-in time limits: 3 minutes for heating and 12 minutes for cooling. This prevents glass from fogging. The AUC sensor registers roughly 0.5V in conditions of typical air quality. The ventilation or fresh air flaps will close (0%) if the AUC sensor voltage rises to 3.0V. The new flaps will read roughly 20% and 100% (completely open) at 2.4V and 2.5V, respectively.

What does a BMW’s Active Guard Plus do?
- BMW Active Guard is a standard feature.
- Optionally, more safety equipment can be installed.
- Euro NCAP safety rating of five stars
The 3 Series received a near-perfect score of 97% for adult occupant safety during the 2019 Euro NCAP test, earning it the full five-star certification. Scores of 87% for pedestrian safety and 76% for safety assist are likewise excellent performances, as are scores of 87% for kid safety.
Why does my BMW have a lane departure indicator on?
The City Brake Activation system and the camera-based Lane Departure Warning and Approach and Pedestrian Warning systems are combined in the Driving Assist feature. At speeds over about 70 km/h, the Lane Departure Warning recognizes lane lines and vibrates the steering wheel to warn the driver of an inadvertent lane shift. If the lane change is intentional, that is, when the turn indicator is on, the warning is not activated.
The Pedestrian Warning with City Brake Activation responds to pedestrians whereas the Approach Warning with City Brake Activation detects automobiles. The Approach Warning initiates a two-stage warning when there is a potential for collision. The instrument cluster’s symbol first illuminates before an audible alarm sounds. In the event of an immediate risk of collision, the pedestrian warning initiates a single-stage warning. The brakes are simultaneously preconditioned for a quicker response if the system forewarns of a probable accident. The system applies the brakes during an emergency.
Along with Approach Warning and Lane Departure Warning, the Driving Assist Plus feature (only available with Automatic Transmission Steptronic) also has Active Cruise Control with Stop&Go functionality. This helps when driving on highways in both emergency and non-emergency traffic scenarios.
In stages, the Approach Warning reacts. The response varies from a visual alert to active braking and even a complete stop depending on whether a vehicle ahead brakes unexpectedly or whether a stationary item is noticed. With the use of vibrations in the steering wheel, the Lane Departure Warning rapidly issues a warning if the vehicle starts to lane-change without the driver’s knowledge.
If the distance control is on, the Active Cruise Control automatically changes its speed to match that of the vehicles in front of it. Otherwise, it maintains the selected speed between 30 and 210 km/h. When the gas pedal is depressed, the Stop&Go feature even manages speed down to a standstill before simply resuming acceleration, for instance in heavily moving traffic.
Is there automated braking in a BMW?
A group of driving assistance and collision-avoidance technologies is called BMW Active Driving Assistant. The Active Driving Assistant is a set of safety features that come standard on more expensive BMW models like the 5 Series and X5. These features include forward collision warning with pedestrian detection, low-speed automatic emergency braking, lane-departure warning, blind-spot warning, and rear cross-traffic warning.
BMW Active Guard is distinct from Active Driving Assistant. Forward-collision warning, low-speed automated emergency braking, and lane-departure warning are all features of Active Guard, which is a standard feature on lower-end BMW models including the 3 Series and X3. BMW buyers who select a model with Active Guard as a standard feature have the option to equip their vehicle with the Active Driving Assistant specification by purchasing a Driving Assistance Package.
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:

An ACU sensor is what?
On tanks with a depth of up to 1.5 meters, the Acu-TracTM Fuel Level Sensor is a non-contact sensor that can be used in place of level sensors (59 inches). There are several output options for the Fuel Level Sensor (analog current loop; ratiometric voltage; or non-ratiometric voltage).
The fuel level sensor also has the ability to handle real-time fuel data and messaging for both on-vehicle and off-vehicle communications on a J1708 data link.
With the help of the fuel level sensor, the user can program tank configuration, digital filtering, sensor mounting offset, full and empty endpoints for gauge drive output, and communication mode.
The non-contact Acu-TracTM range of ultrasonic fluid level sensors are a direct replacement for level senders on tanks with depths up to about 3.0 m.
In order to enhance reliability, it is crucial to comprehend the factors that influence how well an application of ultrasonic distance sensors performs.
On a J1708 data link, the Fuel Level Sensor is capable of processing real-time fuel data and messaging for both in-vehicle and out-of-vehicle communications.
Climate Control sensor: what is it?
There are three key sensors in your automobile that it uses to measure the temperature inside and outside. Since the functioning of the temperature control system depends on these sensors, they should be left exposed and unobstructed.
The solar sensor is situated in the defrost grille in the middle of the instrument panel, right at the top of the dashboard. The sun heat entering the front windshield is monitored by this sensor.
The headliner contains the interior temperature sensor. The air temperature within the car is monitored by this interior temperature sensor.
The front grille’s back is where you’ll find the outside temperature sensor. This outside temperature sensor keeps track of the outside air’s temperature and aids in regulating the temperature inside the car. Any form of covering on the front of the car could result in an inaccurate exterior temperature reading being shown on the instrument panel.
The informative nature of the aforementioned claims warrants independent verification. kindly visit our
The sensor for the climate control is where?
Several sensors are part of the climate control system, which helps regulate the interior temperature of the vehicle. On the upper side of the dashboard is where you’ll find the sun sensor. Under the climate control panel, there is a temperature sensor for the passenger compartment.
What happens if the AC sensor malfunctions?
If your sensor isn’t working properly, you can tell by looking for obvious signs like the ones listed below:
When the temperature in your house reaches the specified point on the thermostat, the air conditioner does not shut off. If the evaporator unit’s temperature sensor quits measuring it, the air conditioner will just keep blowing cool air into the space. This will cause the room to get excessively cold, which could result in higher energy costs and an uncomfortable interior temperature. If this happens, make a call for HVAC repair right away.
When the temperature reaches the thermostat setting you’ve chosen, the air conditioner stops sporadically cycling on and off. The temperature in the evaporator unit might have been misinterpreted by a defective temperature sensor. Your device will keep intermittently turning on and off, which could lead to early failure.
For the season, your monthly utility bills are more than anticipated. Even though there are a lot of indicators that explain why your bills have been higher than usual lately, it’s still wise to have your system evaluated by an HVAC installation firm to save further expenses.
