Reasons Behind Your Volvo’s Airbag Malfunction Light

Posted on | 22 May 2020 By Anita Gaal

Volvo vehicles are well-known for their dependable performance and consistent safety. As a result, it might come as a surprise when you’re driving your Volvo to see the airbag malfunction light turn on. When owning a Volvo, you need to know what this symbol means and why it may illuminate.

Causes of Volvo Airbag Malfunction

Because of the importance of airbag functionality in your car, whichever of these might be the issue, it’s still best that you have a qualified auto mechanic look over your car for safety. Though the airbag light comes on when you start your car as its system tests itself, it should always turn off after a short period of time.

Case #1

Your Volvo has a sensor that tells the car’s computer if the seat belts are fastened when people of a certain weight are sitting in the seats. If there is a fault in the sensor, and it does not detect a passenger or driver, the airbag light will come on. The airbag is in jeopardy of not deploying in a collision because the car has no sensor that someone is sitting in the seat.

There can be some simple reasons for this, such as debris or a coin lodged inside the seat belt buckle. Something like this is a simple fix, but if the airbag warning light comes on, it’s still best to have your car inspected because of the high stakes involved in knowing if you have properly-functioning airbags in your car. If you’ve checked your buckle for debris and do not find any obvious issues, bring your car in to check the airbag sensor.

Case #2

If something inside the airbag is malfunctioning or broken, the airbag warning light will illuminate. Inside the airbag is a clock spring. This is a coil that helps connect the electrical wiring to the airbags. If it is damaged, the airbag won’t deploy during an accident. This is an urgent issue that needs immediate repair.

Case #3

When a car has been in an accident, the force, location, and direction of the crash are all measured instantly by sensors in the car. These sensors help the car’s computer determine if the airbags should be deployed, and if so, which ones will inflate to protect you in the case of a side impact, head on collision, or other crash. This helps make sure that airbags are spared or not deployed if they are not necessary.

In some crashes, these sensors register force that doesn’t necessitate airbag deployment. If you have a very minor collision and the airbags do not need to deploy, your airbag sensors may need to be reset. Without having this valuable component reset, the airbag sensor may not detect a future crash, failing to deploy the airbag when, in fact, this time, it was necessary for driver and passenger protection.

You can see why it is imperative to bring your Volvo in for inspection of the warning light illuminates, indicating any problem with your airbag.

No matter what the cause of the airbag malfunction, it’s essential that your car’s safety is assured by a thorough and detailed check of all your safety systems, so you can drive your Volvo knowing that all of its safety features are fully operational. While it can be helpful for you to know what can be causing problems with your Volvo’s airbags, in the end, all of these concerns will require inspection, repair, and possible replacement to be required.

Volvo Recalls

Some Volvo vehicles in the past have had faulty airbag clocksprings. These models were recalled by the company in 2015. If you’re driving an older model of the car, make sure you know your car’s history so you can be sure that the issues related to the Takata airbag recall don’t affect your safety while driving.

How to Deal With Vacuum Door Lock Failure in a Mercedes

Posted on | 6 May 2020 By Anita Gaal

If you have a Mercedes, one issue you may come across is vacuum door lock failure. When you experience a problem with your Mercedes, you can’t take them to any garage. Your Mercedes requires specific care. At Euro Automotive we specialize in European vehicles, so let’s take a look at vacuum door lock failures and discuss signs of breakdown.

The Function of the Vacuum Door Lock

The vacuum door lock is a feature that was originally designed by Mercedes. Instead of turning gears inside a lock, an actuator forces air through tubes. The technology is vacuum-based and is able to lock all the doors at once.

This type of lock serves 2 purposes. It is a simple way to lock all the doors simultaneously and is also a protective feature that keeps the doors locked until the master lock is disengaged. This makes it less likely for thieves to gain access to your car.

This system has no electrical components. However, after time, it is not uncommon to experience mechanical failure.

Symptoms of a Failing Vacuum Door Lock

Failure of your vacuum door lock will probably not happen all at once. Instead, you may begin to experience symptoms. The door locks will begin to fail separately. One door may have trouble locking or unlocking, then another one. If you begin to have an issue with one door, it’s probably an indication of vacuum door lock failure. Call us to schedule an appointment to have the issue fixed before it becomes a major problem.

Common symptoms to look out for:

• doors lock erratically
• issues unlocking doors
• noises coming from inside the door

Reasons for Vacuum Door Lock Failure

The vacuum door lock system is made up of many components. Any of them could fail, which will leave your car unlocked and vulnerable to thieves. Below are a few reasons you may experience door lock failure in your Mercedes.

Faulty Actuators

Each door has its own actuator. If one fails and begins to leak, you will have problems locking and unlocking the door. In some cases, the actuator can be fixed, but it is often quicker and cheaper to replace the part.

Pump Failure

The vacuum pump controls the air that triggers the locks. When it fails, you will not be able to lock or unlock the doors.

Age

All components will experience wear, and fail over time. Many components in the vacuum door lock system are made from plastic. The plastic often dries out and becomes brittle. The components crack and break apart, which leads to failure. The door lock airlines also wear out and begin to leak. This leads to a lack of air pressure which can make it impossible to lock the doors.

Bad Wiring

The vacuum pump is often located under the passenger seat. When the seat is moved, it can cause the wires to become loose or disconnected. The wires can also corrode due to moisture and become unattached from vibration.

Diagnosing the Failure

Vacuum door lock failure is common in older vehicles. Any of the components in the system can fail. When one does, you will have issues locking and unlocking your doors. Most components are easy to replace. But it isn’t possible to tell which has failed without proper diagnostics.

At Euro Automotive, our expert mechanics specialize in luxury European cars. Whether you are looking for routine maintenance or are experiencing vacuum door lock failure, we can help. You do not have to take your Mercedes to a dealership for service. We can take care of all your service needs quicker and cheaper.
