How often should the engine mounts of a Mercedes-Benz be replaced?
2 Answers
There is no specific replacement interval for the engine mounts of a Mercedes-Benz. Under normal usage, they can last for more than 6 years. However, they should be replaced when signs of cracking, aging, or other damage are observed. Engine mounts: An engine mount is a cushion that connects the engine to the vehicle body. Most are made of rubber, while high-end vehicles may use hydraulic mounts. Typically, engine mounts can last over 6 years under normal conditions without a fixed replacement schedule. However, if inspection reveals cracks, aging, corrosion, or other damage, replacement is necessary. Generally, there are three engine mounts fixed to the vehicle frame. If one is damaged and not replaced promptly, it disrupts the balance and accelerates the wear of the other two. Function of engine mounts: The primary role of engine mounts is to reduce the vibration transmitted from the engine to the chassis. The rubber components in the mounts help absorb resonance generated during engine operation. Some mounts also feature hydraulic pressure reduction to achieve the same goal. If the mounts are damaged, engine vibrations can cause the entire vehicle body to shake.
After driving a Mercedes for so many years, I've realized that engine mounts aren't something you replace on a fixed schedule. My S-Class started showing slight vibrations after nearly 100,000 km, especially with a buzzing noise at idle. A shop inspection revealed cracked rubber in the engine mounts due to aging. The technician explained these wear like shock absorbers—faster if you frequently deal with city stop-and-go traffic or rough roads. I delayed fixing it, and the worsening vibrations eventually loosened the engine bracket. My advice: have them checked during routine maintenance. With Mercedes' complex engineering, early detection saves big. Start paying attention after 80,000 km—don't wait for major issues that compromise comfort and fuel efficiency.
