Hints to Deal with Your Audi ABS Problems Along with the Causes

Audi Illuminated ABS Light

Modern Audis come with an Anti-lock Braking System (ABS), which is an enhanced safety feature in your model. Its main job is to ensure that in an emergency when you slam on the brakes, the wheels don’t lock up. This prevents your Audi from skidding on tires that are locked. The ABS controls the rotational speed of the tire during a heavy braking situation. This is a huge safety feature which allows the driver to steer to safety instead of skid.

How Does the ABS Work?

An Audi with an ABS has many electronic sensors that are continually monitoring speed and other aspects of driving. When the sensor detects a hard press on the brake, which implies there could be a possible wheel lock, it relays a message to a controller. This automatically begins to pump the brake up to 20 times per second, allowing for minute rotation of the tire so it isn’t locked.

Picture a rock skidding on ice: it has no ability to steer itself. It simply slides in the direction its momentum carries it. However, with the ABS, you will feel the brake pedal vibrate and push back as it allows for traction so you can steer on the road’s surface and direct your car. Remember: the ABS won’t reduce your stopping distance. That’s still the job of the whole braking system. However, it will help with traction and steering.

Reasons the ABS Goes Bad

Several issues can contribute to ABS failures. Here are a few:

  • ABS Pump and Modulator Problems: This system can go wrong in any car. However, Audis have been known to have these issues. If you notice the ABS light is on, take your Audi to a professional mechanic immediately as this problem will only get worse.
  • Speed Sensors: The speed sensors that monitor the wheels can accumulate dirt and debris and have been subject to some kind of physical damage, wiring problems, or corrosion. Any of these issues can cause the sensors to fail. The ABS light on your dashboard will light up if there is a problem.
  • ABS Module: Damage due to water or electrical issues in the wiring or connectors can lead to a malfunctioning ABS module.
  • Faulty or Loose Wiring: Due to the vibration of the vehicle, It is not uncommon for the wiring in the ABS module to become loose or get disconnected. This will certainly result in the ABS system to stop working.
  • Faulty Speedometer: if the speedometer is not measuring your Audi’s speed correctly, it may have an affect on the braking system.

Symptoms of a Malfunctioning ABS

Keep an eye out for these signs. It may mean that your ABS is not working:

  • Brake Pedal: If you notice the brake pedal is not responding or is difficult to control, such as being too stiff, too loose, or spongy, there might be a problem with the ABS unit.
  • Brakes Lock Up: If there is a clicking noise when you depress the brake pedal, or it simply locks up, that is concerning.
  • Increased Braking Distance: If you notice it takes longer to stop, that is a cause for worry. It is dangerous to drive with poorly functioning brakes. Make sure you have your Audi inspected and repaired.
  • ABS Light On: If there is a problem with the ABS module, the ABS light will turn on in the dashboard. This is one of the malfunction indicator lamps (MIL) that indicate there is a problem somewhere in the car. A professional mechanic can diagnose which part of the ABS is giving trouble.
