To conclude: a concern of reversing radar could quickly arrive.
When you plan to make repairs to a professional you will need to count approximately between 200 and 300 €. If that doesn't work you will have to remove the bumper of your Bmw X1 by removing a few screws, disconnecting the sensor connector and replacing the defective sensor. When you have located the damaged sensor, try to replace it on its support so that it returns to its initial position. Perform the test on each sensor so as to identify the one that no longer works.
If the ultrasonic waves work you will hear a small sizzle otherwise if you do not hear anything, then it means the sensor is no longer working. Locate the sensors on the rear bumper of your car and bring a coin closer. For this we recommend that you put the reverse gear of your car, but also put the handbrake. So you will have to find the faulty sensor. Then when this has not solved your problem, start by checking the sensors. This could resolve your concern fairly quickly.
How to fix a backup radar problem on Bmw X1?įirst of all, before a repair on your Bmw X1, we recommend that you start with nettoyer the bumper of your car since it is possible that dirt prevents the sending of ultrasound. You may be able to spend some time checking it, using your Bmw X1's notebook, but be aware that this is really less common. If this is your problem the reverse lights will not come on either.įinally, as it is an electric circuit, it is always possible that the fuse reversing radar blown.
That is, the devices do not engage when you put the reverse gear. It is also possible, although it is less frequent, that you have a problem at the level of rear contactor. Then you will get the continuous audible signal when you engage reverse gear. Otherwise it may happen that the sensors become clogged with impurities for example mud, plants… which prevent the diffusion of ultrasound. In this case, it is likely that the reversing radar no longer emit sound because a sensor is damaged or you have an alternative sound signal. Indeed when you had little ones clashes in the back of your car, it sometimes happens that this has displaced the sensors, consequently distorting the calculation of the radar. Please note, a reversing camera should not replace the controls in the mirrors.Īs stated above, the reversing radar operates thanks to sensors arranged at the rear of your vehicle, so generally breakdowns will be due to them.
The central will receive the information and send an audible signal to the driver to help him examine the distance left behind the car. After that they will send this information to a electronic control unit through electrical connections. Sensors will time the reception time of the ultrasound echo in order to calculate the distance. To calculate this the captures send ultrasonic (ultrasonic waves) which when they reach the external element will send back an echo.
These sensors will calculate the distance that separates your car from an external object, such as a wall or another car. Note that in general the sensors are placed at a distance of 50 cm from the ground on the bumper, in order to be able to measure the appropriate distance to ring. It works using sensors, on average four, arranged on the rear bumper of your car. Thus the sound signal starts on average at 1 m from your vehicle and becomes continuous at 5 cm. Usually intensity the beep will increase as the distance decreases so as to accentuate the alert. This one goes ring when you are close to an object behind your car. The reversing radar is activated as soon as you engage the reverse of your Bmw X1.
