First, disconnect your automobile battery’s positive cable. Then, maintain your foot firmly on the brake pedal to shut off the car’s electrical system. The core computer of the car will be reset as a result. Reconnect the cord to re-establish electricity. This should reset the light if the system doesn’t still have a problem.
Step two: You might need to replace the ABS sensor if the light returns after being reset. To do this, unhook the sensor’s wire and detach the housing from the sensor, which should be affixed to the wheel hub. Next, mount and attach a fresh sensor. It’s possible that using the aforementioned technique, you’ll still need to restart the computer.
Step Three: If the light continues to illuminate, you should utilize an ODB code reader to identify the issue because the car still thinks there is a problem that justifies the light. Take your car to a shop to have the issue identified and fixed if you don’t have an ODB code reader.

Why is my VW’s ABS light on?
If the ABS service light on your Volkswagen is on, a fault has caused the antilock system to be disengaged.
Regular brakes on your car should be functioning flawlessly, but the ABS system that stops the wheels on your car from locking up when you brake won’t. This feature will also be turned off if your car has a stability or traction control system.
To track a wheel’s speed, an ABS sensor is put on each one. When you stop, if one wheel spins more slowly than the other three, it is likely locking up, which could lead to skidding and a loss of steering control. Usually, ABS will step in and quickly pump the brakes to the wheel that is locking up, allowing it to spin and preserving steering and braking control for the driver.
What follows is what makes your ABS malfunction:
- a road grime- or damage-covered wheel-speed sensor
- a system fuse that has blown
- between the sensors and the ABS controller, a broken wire
- A malfunctioning ABS controller
How can the ABS be disabled in a Volkswagen Jetta?
The ESP should be switchable using a switch on the center console, however it is not feasible to turn the ABS on or off.
The Volkswagen Jetta’s ESP (Electronic Stability Program) can be turned on or off via a switch on the dashboard, but the ABS (Anti Lock brake System) cannot be disabled. However, it is advised to always keep ABS and ESP on for safety reasons as this provides superior stability and effective braking even on slick and rainy surfaces.

Why won’t my ABS light go out?
An issue with various parts inside or connected to the anti-lock brakes may be indicated by an ABS warning light that illuminates and remains illuminated. For instance, specialized sensors keep tabs on the wheels’ speed. The ABS warning light will remain illuminated if one or more of these wheel speed sensors are malfunctioning or broken. The same holds true if there is a wiring issue.
Other potential issues could be with the system’s hydraulic pump, solenoid valve, ABS control module, or a faulty power relay to the module. The brake master cylinder’s braking fluid level dropping or a fuse blowing can both cause the warning light to illuminate (or in the ABS reservoir if the vehicle is so equipped).
Can I drive with my ABS light on?
As regular braking is unaffected by the ABS light, you can continue to operate the vehicle while it is illuminated. However, since your ABS system aids in stopping control and driving without it can be risky, we wouldn’t advise you to do this. You want to know how your car will function if something goes wrong. Without a fully functioning ABS system, your car could not respond to hard braking as it should.
Why is the ABS light on on my vehicle?
The standard brakes on your automobile should still function properly, however the antilock system that prevents wheels from locking up while braking will not. Additionally, because traction control and stability control rely on the same wheel-speed sensors as the antilock system, those features will also be disabled if your car has them.
All vehicles made in 2012 and later are obliged to feature traction control, ABS, and stability control. All or some of those features can be found in many vintage vehicles.
Every time you start your automobile, the ABS light (often yellow, amber, or orange) should briefly illuminate as a system check. If the light continues to illuminate, the system has been shut down because something isn’t operating properly.
With ABS, sensors that are put on each wheel track how quickly the wheels are spinning. When braking, if one wheel is rotating more slowly than the others, it means it is locking up, which could lead to skidding and a loss of steering control. In order to prevent further wheel locking, ABS is designed to quickly “pump the brakes at the locking wheel, allowing it to spin so that the driver retains braking and steering control.”
What causes this is as follows:
An ABS sensor warning light can also be activated when a pump and valve that apply the proper amount of braking fluid pressure to each wheel to prevent locking do so.
If the regular brakes’ red warning light illuminates, your car is likely losing braking fluid or the brakes are so worn that you can’t stop as quickly as usual. Any of such circumstances calls for prompt attention and perhaps repairs.
Q: Is it safe to drive a car with an ABS light on?
Yes, it is secure. Even having the ABS light on, the car brakes will continue to function normally when braking. But in cases of hard braking, the brakes will lock up, causing the wheels to skid. When you apply hard braking on ice during the winter, your ABS system is crucial to prevent your wheels from locking up.
Driving with the ABS light on in the winter is risky since your car won’t be able to withstand emergency severe braking. The safety feature gives you steering control by reducing your stopping distance and safeguarding you from mishaps.
Q: How much does it cost to fix the ABS system?
Ans: If you include the price of an ABS diagnosis and labor fees, it will cost about $200. The estimate, which is location-specific and excludes taxes and fees, is available here.
However, depending on the ABS module component, there may be an additional cost of $200 to 950 if you need to replace the ABS system. Many mechanics will repair your ABS for a total of $340 to $1100.
Q: Can Low brake fluid cause ABS light to come on?
Yes, when there is insufficient brake fluid in the ABS fluid reservoir, an ABS light will illuminate. You have an abnormally low fluid level, according to the warning light. Check to see if the alert goes away by shutting off the engine and starting it again. If not, look to see if the light is flashing. If so, it indicates that the brake fluid level is only a little bit low.
Q: Can worn brake pads cause ABS light to come on?
Ans: No. The ABS light won’t turn on because your brake pads are worn out. A blown fuse, an irregular wheel sensor, and low brake fluid levels all cause the light to come on. As a safety measure, it’s wise to change old brake pads in order to boost stopping power. To increase your car’s braking effectiveness, replace worn brake lines.
Q: What can cause ABS to fail?
Unless the ABD controller is malfunctioning due to one or more sensors or defective sensor connections, ABS rarely goes wrong. The most frequent reason is that metal shavings, debris, or corrosion have contaminated the sensors. Only after you slam on the brakes and realize that the wheels are locking up as you drive will you become aware of a malfunction.
What does it cost to repair the ABS light?
The initial diagnosis will cost you roughly $100 from a qualified mechanic. Because so many ABS parts are easily accessible, labor costs for the majority of repairs are typically in the $100150 area. A standard ABS sensor will cost between $80 and $125, however on some makes and models (GM, Ford, and others), the sensor is included in a hub/bearing assembly, raising the cost to around $350. Parts costs rise into the $500 to $800 area for more serious problems like those with the ABS pump or computer.
Can a low battery turn on the ABS light?
The ABS light can illuminate as a result of a poor battery. The ABS light could also come on if your brake light is broken or burned out.
Can ABS be impacted by low tire pressure?
Yes, low tire pressure can cause your ABS light to turn on, to give you the quick answer. When braking, the ABS (anti-lock-braking) system is in charge of keeping the wheels on the ground.
This indicates that one of your tires could not be properly inflated. This may also cause the ABS light to illuminate for a number of reasons. Wheel speed sensors are installed in your automobile at each of the four wheels. These sensors track wheel speed and continuously provide this data to the ABS and traction control systems, which are managed by the vehicle’s ECU.
When the ECU detects an anomalous speed under certain circumstances, it activates the traction control or ABS as necessary to adequately and safely control the vehicle. These sensors may occasionally malfunction or stop operating altogether, delivering the ECU erroneous indications. You might encounter the symptoms you’ve mentioned when this happens.
These erroneous or imprecise signals may unintentionally activate the traction control or ABS systems. The change in tire pressure may have also resulted in the ABS light turning on, depending on the signal sent from the wheel speed sensors to the ABS system.
Why Wont My ABS Light Go Off?
There was a problem with one or more ABS system parts. It may be an erratic issue, such as a voltage drop caused by a faulty battery or an ABS system failure. In either case, it must be reset because it won’t go away.
How Do You Bleed ABS Hydraulic Units?
You must press the air out of the system in order to bleed the hydraulic unit. You simply need to squeeze the air out of the brake line to each brake caliper if you didn’t repair or loosen any hoses at the booster or ABS unit.
The proper size spanner for the bleed nipple is what you require. A second person to depress and hold the brake pedal, as well as a clear Flexi hose that fits on the caliper’s nipple.
The assistance should begin by applying the back brakes, pressing the pedal 48 times until they encounter some resistance, at which point they must maintain pressure. Remove the dust cap, then carefully open the bleed nipple with a flexible hose placed over it. Bubbles and a tiny amount of liquid ought should emerge.
While your aide continues to apply pressure on the brake, close the nipple. Repeat this process until the caliper is clear of all bubbles. Repeat the process for each of the four calipers’ brake fluid levels.
Use a large syringe to suction the air out of the flexible tube end of a caliper if you are having trouble doing so and the braking fluid isn’t coming out. The brake line and caliper will be cleared of air after this procedure.
You will probably require a scan tool to cycle the pump if air got trapped in the ABS hydraulic unit; for details, click this page.
Can You Drive Without ABS?
When you apply too much braking pressure, the wheels will lock up since the ABS isn’t functioning. You might have to pump the brakes in an emergency to counteract the effects of the ABS and lessen wheel lock.
