When the ABS ecu detects under-voltage, such as a disconnected or low battery, ESP activates. If the issue is only a low voltage fault, it will go away when you start the car, like lee69 suggested.

What does an Audi’s ESP issue mean?
This warning light, which is quite contemporary in modern cars, typically resembles the image of a car swerving. The Electronic Stability Program, or ESP, is intended to increase a car’s stability when navigating challenging terrain. Inclement weather while driving may cause this light to come on. If the warning light is flashing, the ESP traction control is on, and you will notice that your wheels have extra traction. This may also happen when traveling on smooth tarmac, which may indicate that you need to replace your wheel sensors. Your ESP traction system has developed a malfunction if the light is on but not flashing.
What triggers the ESP light to illuminate?
A damaged ABS sensor or ABS ring is the most frequent cause of the ESP light to come on. Additionally, problems with the throttle body, the brake pedal switch, or the steering sensor may be to blame. If it blinks while you’re driving on a slick surface, it’s functioning properly.
Together with the ABS, the ESP operates. Because of this, it is challenging to pinpoint the issue’s root cause right away.
It is usually advised to examine the fault codes with a diagnostic scanner in order to identify the issue that is producing the ESP light.
Faulty wheel ABS sensors
The ABS control unit receives data regarding each wheel’s speed from the wheel sensors. When one or more wheels begin to slip, the ABS control unit measures this data and makes the required adjustments.
If one ABS sensor malfunctions, it may believe that one wheel is slipping while it actually isn’t, which will turn on the light.
Faulty ABS rings
The ABS rings are subject to the same rules. The ABS rings, which are used to detect wheel speed, occasionally break, causing the ABS sensor to read the wrong speed.
Faulty Throttle body
When your automobile slips, the ESP system’s power output is managed by the throttle body. The ESP light will illuminate if there is a problem with the throttle body.
Faulty Brake Pedal Switch
When you apply the brakes, the ESP system needs to be aware of it. There is a brake pedal switch fitted on your brake pedal in order for this function to operate as intended.
The ESP light could turn on if this switch is malfunctioning and transmitting incorrect data.
Faulty Steering Angle sensor
The steering angle is another factor that the ESP system considers when determining what to do when sliding occurs. The ESP light could turn on if your steering angle sensor is degrading or is not properly programmed.
ESP fault: what does it mean?
According to the manufacturer, the ESP is typically referred to differently, but for Mercedes, it is still just called ESP. It stands for Electrical Stability Program and is a sophisticated electronic technology built into every new automobile that increases safety in a variety of road conditions. The dashboard light will turn on when the ESP system activates, allowing drivers to see it.
The ESP system will engage to compensate for the driver if you have to swerve to avoid a moving vehicle on the highway or make a quick turn for any reason. This may involve using the Traction Control (TCS) or Anti-Lock Braking System (ABS) to make adjustments and maintain the vehicle on the road during difficult maneuvers.
What does the Audi A3’s EPC light mean?
Audi Vehicles Have an EPC Light When your car loses electricity, an EPC light will normally come on. Your Audi’s computer may lower power output to ease the strain on the engine if it notices a fault with any of the throttle system’s parts.
What location does the ESP sensor have?
the engine room It can be found in the engine room. The system’s electrical and electronic activities, as well as all control operations, are handled by the control unit.
Can I drive while the ESP BAS light is on?
It is unsafe to drive when the ESP BAS light is on, so refrain from doing so. To keep yourself and other drivers safe on the road, this problem needs to be fixed as quickly as possible. It might be a small thing, but it might also be something really serious. You never know when you’ll need your ESP system, so it needs to function effectively all the time.
A poor ESP system could cause you to have a serious accident. For the car to stay on the road, traction is required. Additionally, if these sensors aren’t functioning, you can lose traction in the snow or when cornering. While traveling, you never know what kind of traffic circumstances you might encounter. You must always be ready for such events.
When the electronic stability control light illuminates, what does that mean?
The ESC light on the dash may imply different things, therefore it’s critical to understand how your specific control system operates. Usually, while the computer is actively attempting to maintain traction control, the light will come on. Only when the vehicle is not under control will this light continue to be on. If the light never goes out, there is probably a problem, or the system has been manually turned off.
To distinguish between a malfunction and the system being off, the majority of vehicles having a button to activate the stability control should also have off printed beneath the sign. The system will be temporarily turned off if a problem is found and left that way until it is fixed. In order to help you find the problem, you should also ask a qualified technician to run a code scan on the car’s computer.
Are ESP and traction control the same thing?
ESP and traction control are distinct concepts. It is often managed by your ESP, although it has a different function. Traction control, as its name suggests, is intended to increase the traction of your car’s driven wheels while under power, as opposed to preventing your automobile from sliding or spinning in bends.
Imagine you need to enter a roundabout quickly. You see a space in the traffic, so you immediately start to accelerate from a stop. However, you do it too soon, and your engine’s power overwhelms the grip of the tyres, causing them to spin and sending you quickly nowhere.
When traction control is engaged, performing the same maneuver will cause it to interfere, either by decreasing engine power or by braking a spinning wheel to transfer power to the wheel that has grip.
The goal is to meter out power while utilizing the available grip. It works especially well on slick surfaces.
However, there are situations in which traction control isn’t the best, especially when you need your wheels to spin, such as when you’re trying to free the car from snow. The majority of mainstream cars’ ESP buttons disable traction control rather than the ESP, allowing the driven wheels of your car to spin freely and give you the momentum you need to escape.
How does driving without ESP affect things?
By default, ESP is enabled, and if the car starts to veer off course, the system will help you regain control. For instance, if you let the back end go, the throttle will automatically be lessened, and the brakes will be applied to some wheels in order to turn the car around and regain control of the back end.
When the stability control light is on, can I drive?
Even when the ESC light is on, you can still drive, but you must exercise caution by slowing down. Additionally, get a qualified technician to deal with any ESC-related problems as soon as feasible. Give our vehicle repair facility a call right now if you require electronic stability control repair!
