Mercedes models have vacuum door locks that are specific to their unique design. As a luxury vehicle, Mercedes goes about things differently than other brands. Its vacuum door locks are one example of how this vehicle brand elevates itself from others. Yet, this distinctive feature introduces a new challenge to Mercedes models as well. The vacuum door lock can fail, which can allow your car to remain unlocked when you thought otherwise. More dangerous for your belongings than your passengers, vacuum door lock failure can be caused by a few different reasons. Let’s take a look at how certain components and systems can affect the vacuum door locks in your Mercedes vehicle.
How does a vacuum door lock work?
By using vacuum and pressure, all the doors in a Mercedes-Benz model lock at the same time. While this makes door locks simple and easy to use, it also creates the need for all locks to be pressurized at the same time. If just one is off, it can compromise the whole system. Yet, when this system does work, it can keep the doors of a Mercedes-Benz from being pried open thanks to this pressurized approach. There are no electrical components in this system setup, but mechanical failure is a prominent issue.
Top Reasons For Vacuum Door Lock Failure In Mercedes
As a system with many components, there are several things that could go wrong and cause your Mercedes vacuum door locks to fail. If this mechanical failure occurs, the doors to your Mercedes could remain unlocked and allow individuals with bad intentions to look through your items or steal your personal belongings.
- Vacuum Pump Failure: A vacuum pump sits behind the front passenger seat of your Mercedes, and it works to keep your vacuum pump system working properly. Should it fail, you may have problems locking and unlocking the doors of your Mercedes.
- Leaky Actuators: Actuator problems can lead to issues with the doors of your vehicle locking or unlocking. It is possible to repair an actuator, but more often than not, they must be fully replaced.
- Wear and Tear of an Aging System: As your Mercedes gets older, it becomes more susceptible to door lock issues and failure. Many components of this system are made of plastic, which can become dry and brittle to the point of breaking.
What To Do When Your Vacuum Door Lock Fails
Fixing the vacuum door lock system in a Mercedes-Benz is a complex process that requires professional guidance and care. A system of locking and unlocking, as well as blowing air into and out of the system is often required to even determine if the lines are still good. Not to mention, there is no way to know which part of the vacuum door lock system isn’t working without help from a skilled mechanic. Seeking professional assistance for this issue is recommended.
