How To Reset Airbag Light Audi A4

With the use of an OBD diagnostic tool, you can turn off the SRS or airbag light on your Audi. You can acquire this from a retailer of vehicle parts. The On-Board Diagnostics (OBD) computer in the car can be used by the OBD diagnostic equipment to interpret issue codes. Then, using the same tool, you may reset and clear the light from the instrument panel after you’ve fixed the car. Most auto parts stores will let you borrow one for free if you don’t want to buy one. Usually, but not always, the mechanic who works on your Audi will reset the light.

Step 1

Park on a level, flat surface. On the Audi, look for the OBD II port close to the hood release. The OBD II interface or diagnostic port are other names for the OBD II port. Connect it to the OBD tool once you’ve found it.

Step 2

Turn the ignition to the “on” position and insert the key. Watch the diagnostic tool’s face and wait for the issue codes to appear. To delete the codes and reset the SRS light, look for the “Delete” button or menu command and hit it.

Step 3

Turn off the car and unplug the OBD diagnostic instrument from the port. Give it a minute.

Check the instrument panel after starting the engine to see if the SRS or airbag light is still on.

How can I turn off the airbag light?

The airbag light (also known as the SRS light) should ideally only turn on after an accident, after the airbag has been deployed and filled with either argon or nitrogen. The airbag light can, however, remain on due to other conditions, such as a component or sensor problem. Having said that, automobile owners would benefit from using the following instructions and a handheld airbag light reset tool.

Turn Your Ignition on and Off.

When you experience the same problem, you should start by following this technique, which is identical to resetting the airbag light on a Toyota Camry. It needs timing the airbag light and has four straightforward stages that are simple to complete.

First, activate the ignition. Wait for the airbag light to turn on next; it typically illuminates for seven seconds before turning off automatically. After waiting three seconds, immediately flip the ignition switch off. Before starting the engine, go through the basic procedures a couple of times. Your car’s airbag light should illuminate for seven seconds before turning off permanently if everything is done correctly.

Restart Your Vehicle and Do a Test Drive.

Your car can require a power cycle, just like your cell phone. But not all automobiles will be compatible with this. But it might for individuals who occasionally seem to experience issues. If the airbag light does not stay on for too long, you would be aware to do this action. Start your ignition again, then take a little drive. If the airbag light eventually stops flashing for good, the issue has probably been resolved. If not, carry out the remaining tasks on this list.

(TIP: Check the wiring system under the driver’s and passenger’s seats before starting your car. Check the connector plug for any corrosion or loose wires. If none, spritz an electronic cleaner on the connecting plugs.)

Examine the Passenger Airbag Switch.

When attempting to turn off the airbag light, one of the first things to check is the passenger seat airbag on/off button (only present in some vehicles). It’s possible that someone accidentally switched it off, leaving the airbag light on. Normally located on the passenger side dashboard, this button can occasionally be seen by opening the glove box or passenger door.

Inspect Whether Seat Belts Are Fastened or Working Correctly.

Since the SRS is concerned with driver and passenger security, it can detect ill-fastened seatbelts and turn on the airbag light. The airbag can even be turned off automatically if the seatbelt is not used. To that end, make sure the appropriate operation of seatbelts and seat belt sensors is on your list of things to rule out. The same advice would be given by mechanics to those performing a Jeep Wrangler airbag light reset.

It may seem absurd, but even seemingly insignificant items like spare change can cause seat belt sensors to malfunction. A tiny bump or pothole can cause a small coin to fall near the seat belt fasteners and get lodged between the sensor and the buckle. When this occurs, the sensor might not detect when a seat belt is fastened, which could result in the airbag light turning on.

Check the inside of the buckle to see if anything is stuck there before replacing your sensors. Usually, it is not as expensive to remove any obstructions from inside the seat belt fastening as most car owners believe. If your seat belt’s components can’t be changed separately and the sensors are built into the seat belt, the opposite is true.

Verify That the Passenger Seat Sensor Is Not Applied.

Some cars contain a passenger weight sensor that is extremely sensitive. The issue with these particular vehicles is that placing a big box or container on the passenger seat is all it takes to trigger the sensors. The airbag light therefore comes on.

There are two ways to deal with this.

Either take the item out of the backseat, or fasten the seatbelt. If the latter fixes the issue, it will demonstrate that the sensor was used, resulting in the airbag light turning on. When the seat belt is buckled and the airbag light disappears but nothing is in the seat, the passenger seat sensor is likely malfunctioning. The decision to keep the seat belt fastened while driving or to replace the sensor is then yours to make.

Use a Scanner With an SRS or Airbag Light Reset Option.

If you enjoy working with your hands, you can get a scanner with SRS capacity to reset your airbag light. Just be aware that not all OBD-II gadgets can automatically reset airbag light. It’s wise to do some study before buying an OBD-II scanner with the capability you require. I’d suggest the Foxwell NT634 OBD-II Scanner (see on Amazon). This device shows error codes that assist you determine how to remedy the problem or when it’s best to have your car serviced.

Address Faulty Airbag Sensors.

Particularly with more contemporary vehicle makes and models, sensors are crucial to a car’s operation. For starters, sensors make sure airbags inflate in the case of a collision. In specifically, the SRS functions with the help of several sensors placed in various parts and/or components of the vehicle. You will undoubtedly notice the airbag light turning on if any of these sensors corrode, fail, or stop functioning.

Airbag sensors occasionally suddenly activate and for no apparent cause. If the automobile has experienced water damage, they may potentially malfunction and turn on the SRS light. Additionally, there are instances where the airbag system control unit may have just failed. If any of these things happen, the issue might be resolved by replacing the faulty sensors, control unit, or water-damaged parts.

Fix or Replace a Non-Working Clock Spring.

The clock spring, sometimes referred to as a spiral cable, coil assembly, contact reel, or cable reel assembly, is a significant part that, if destroyed or damaged, can result in the airbag light turning on. Not only is it one of the most frequent causes of a flashing airbag light, but it is also one of the most costly to fix (at least $400). If you change the clock spring yourself, you can save money as long as you use extreme caution and follow the manufacturer’s recommendations.

If you believe it to be the issue, you will need to gain access to the interior of the steering wheel(view on Amazon) to make the necessary repairs. This shouldn’t be a cause for concern because the full procedure just requires 10 stages and takes under 20 minutes to complete:

How to Fix a Clock Spring

  • Wait for the capacitors to drain for at least ten to fifteen minutes after removing the negative battery line from the terminal. (Note that merely disconnecting the battery terminals from the car will not cause the airbag light to turn off.)
  • Hold the center of the wheel (where the airbag is located) in place while the wheels are straight and look for the screws. After that, unscrew them.
  • Pull the airbag away from you to remove it, then unplug the connectors (you may use a pick to slide the yellow clips out when doing this). The screws holding the steering column trim in place are also visible while turning the steering wheel from left to right.
  • Mark the location between the steering wheel and steering column trim with two pieces of painter’s tape when the steering lock is activated. When later putting the steering wheel back in its original position, this reference point will be useful.
  • With a breaker bar, loosen the steering wheel nut without taking it off entirely.
  • Once the wheel is free, take off the nut and wheel to reveal the clock spring.
  • Disconnect the harnesses at the bottom or back to remove the clock spring. Put a fresh clock spring in its place. Bend the tab until it snaps to release it.
  • When reinstalling the steering wheel, use your tape marks as a guide to align it correctly.
  • Install the harnesses and the airbag after tightening the steering column nut with a torque wrench (or your hands and a breaker bar).
  • Reconnect the negative battery terminal and reinstall the trim piece on the lower steering column (see on Amazon). After completing the last step, your airbag light should stop flashing.

Make Sure the Airbag Is Not Defective.

Although uncommon, malfunctioning airbags do happen. It might be the cause of your inability to reset the airbag light. If it does prove to be the offender, be aware that you cannot solve this problem by yourself. It will cost several hundred dollars and professional assistance to solve this issue.

Replacing airbags normally costs between $200 and $1,000, depending on the type, model, and complexity of the SRS in your car (without labor fees). Depending on which airbag is broken, labor expenses change. Compared to side or passenger airbags, driver-side airbags have proven to be simpler to replace. As a result, working on the latter results in higher fees. Both can be pricey, but neither is something you should put off.

Seek Assistance From a Professional.

If everything else fails, have a mechanic work on your car. The cost of taking this path will be more, but the mechanic should correctly determine what is causing your airbag light to flash and fix the issue long-term. New vehicle owners, in contrast to tech-savvy drivers, would largely think about this as their first option.

Can the airbag light be reset without a tool?

Without a scanner, most automobile models make it difficult to reset the airbag light. This is a safety warning since, when the airbag light appeared, you should always fix the problem. Fortunately, if you fix the issue, the airbag light will typically also turn off by itself in many automobile models.

However, in some older vehicles, the airbag light can be reset without a scanner by disconnecting the battery wires.

Make that there are no loose wires or rust in the connector plugs in the wiring system under the driver’s or passenger’s seat. Restart your car after spraying an electronic cleaner on the connecting plugs.

If you can’t detect any issues there, you should really invest in an OBD2 scanner or have a shop interpret the codes because otherwise you’ll have to guess what the issue is.

What is the cost of turning the airbag light back on?

Reset Airbag Light, at No. 1 This procedure typically takes several hours and costs a few hundred dollars, though depending on the car, it might cost as much as $600.

The airbag light stays on for what reason?

A problem with the seatbelts or airbags is indicated by the airbag light. Therefore, it’s usually not a good idea to drive when the airbag light is on. We advise having it towed to the dealership rather than driving it yourself if it continues to flash inside your car.

Driving while the airbag light is on is it safe?

When the airbag light comes on, the vehicle’s airbag system is malfunctioning. Due to this flaw, the airbag is unlikely to deploy after an accident. As a result, it is not advised that you use the car until the system has been fixed.

Never disregard the important caution. There’s no need to gamble with the car, even though it doesn’t make it unsafe to drive.

The light does, however, show that the SRS parts are not functioning properly. This may potentially indicate that the airbags won’t activate in the event of a collision. You shouldn’t wait until you are involved in an accident to determine whether the airbags will keep you safe.

Can a blown fuse turn on the airbag light?

The car could have blown a fuse, for example. There are other fuses that could be to blame, but fuse #13 is most likely the one. You probably need to change fuse #13 and perhaps other fuses if your airbag light is on and your rear windshield wiper is not working. The airbag light can undoubtedly turn on as a result of blown fuses.

The airbag light may also abruptly turn on in a number of other situations. A mechanic or auto parts store should be able to decipher the code that the airbag system emits when it is acting up, which will give them a hint as to what specific issue the airbag is experiencing. There are numerous potential issues with the airbag because it is a complicated system of sensors, wiring, and programming that must suddenly activate during an accident after lying dormant for years. Check the fuse box to see whether you have a blown fuse first, but if not, you’ll likely need to take it to the dealer or a qualified mechanic for service.

Why is the passenger airbag in my Audi off?

If your passenger is light enough for the weight sensor to notice that they are in the seat but not so light that it would be prudent to deploy the airbag, your passenger airbag will not deploy. The airbag’s deployment would be risky for the person in this chair, according to the sensor, because they are too light.

How can the airbag in an Audi A5 be disabled?

Use the emergency key Link to flip the key-operated switch to the “OFF” position to deactivate the front passenger’s airbag (Fig. 1). Turning the key to the ON position will reactivate the airbag for the front passenger.
