Front Hydraulic Engine Mount

High-Performance Drivetrain Vibration Isolation for Audi A6 and A6 Quattro

Restore the signature smoothness and cabin quietness of your Audi with this Premium Front Hydraulic Engine Mount. Unlike standard rubber mounts, this unit utilizes an internal fluid-filled chamber (hydro-mount technology) to provide superior dampening across a wide range of engine frequencies. Over time, these hydraulic seals can fail, causing the fluid to leak out and the mount to collapse. This results in excessive engine movement, vibrations felt through the steering wheel and seat, and harshness during gear transitions.

Engineered to handle the high torque output of Audi’s turbocharged engines, this mount serves as a critical structural anchor. By maintaining proper engine alignment, it protects secondary components—such as CV axles, exhaust downpipes, and cooling hoses—from the damaging effects of excessive powertrain "pitch."

Fitment Verification and Vehicle Applications

This hydraulic mount is designed for the following applications:

• Audi A6 (Front Left): 2012, 2013, 2014, 2015.

• Audi A6 Quattro (L4 2.0L - Front Right): 2013, 2014, 2015, 2016, 2017, 2018.

• Fitment Note: While this mount is position-specific for the models listed, we strongly recommend verifying your engine code (such as the 2.0L TFSI) to ensure exact compatibility with your vehicle's electronic or vacuum-assisted mounting system, if equipped.

Installation and Technical Tips

• Identify Hydraulic Failure: Look for signs of dark, oily residue on the body of the old mount or the subframe below it. This is a definitive sign that the internal hydraulic fluid has leaked and the mount is no longer providing adequate dampening.

• Support the Engine: When replacing a mount, use a professional engine support bar or a floor jack with a wide wooden block to safely support the oil pan. Never lift the engine directly by the oil pan without a weight-distributing block, as this can crack the aluminum pan.

• Check "Active" Connections: Some Audi models utilize vacuum-actuated or electronic engine mounts that adjust stiffness based on RPM. If your original mount has an electrical connector or vacuum line, ensure those systems are inspected for integrity before installing the new unit.

• Symmetry and Balance: If one hydraulic mount has failed, the other is likely under increased stress and near the end of its service life. Replacing engine mounts in pairs (Left and Right) is the best practice to ensure the engine remains perfectly level and the load is distributed evenly across the subframe.
