How do you know if your Audi needs an engine mount? If you experience vibration while you’re at a stop light or a continuous rough idle at any time, you may need Audi engine mounts instead of a tune-up. The vibration dampening effect of the engine mount may be diminished, which will transmit the vibration and noise from the engine, trough the chassis (frame) and into the cabin. Have your engine mounts checked regularly, they are one of those items that are often overlooked.
Why do engine mounts go bad? Engine mounts go bad due to age and stress. The rubber casing will deteriorate after time, much like a rubber band will loose its elasticity over time, which will start to develop small cracks, which will in turn, cause the fluid from within to leak out. Once the fluid leaks out of a liquid-filled engine mount, it should be replaced. Not doing so will cause vibrations and noise to be transmitted into the cabin.
Why are they liquid-filled? The engine mounts are liquid-filled to increase the dampening effect of the vibrations and noise generated by the engine while running. It’s very similar to a jelly filled seat-pad or the discs between the vertebrae, once it ruptured, then the bones will smash against each other causing damage and pain.
How often do motor mounts fail? It’s hard to say, however, it is a good thing to have them checked regularly on every service, including routine oil changes. Motor mounts are one of the most overlooked items during servicing the car and will contribute to a smooth running engine and eliminate the vibrations felt in a steering wheel or one’s seat, once repaired.
