Frequently Asked Questions
Is this mount for the Left or Right side of the engine?
This specific part number (A2122404917) is engineered for the Front Left side of the engine. On Left-Hand Drive (LHD) vehicles, this is the Driver's side. The left and right mounts on the W212 are often tuned differently to handle the engine's specific rotational torque, so they are not interchangeable.
How can I tell if my hydraulic engine mount has failed?
The most common symptoms include a noticeable vibration in the cabin when the vehicle is in "Drive" or "Reverse" while stopped at a light. Visually, you may also see dark, brownish hydraulic fluid leaking down the side of the mount or onto the subframe below it.
Should I replace the right engine mount at the same time?
It is highly recommended to replace engine mounts in pairs. Because both mounts endure the same mileage, heat cycles, and engine weight, if the left side has collapsed, the right side is likely at the end of its lifespan. Replacing only one can lead to an unevenly seated engine and premature failure of the new mount.
Will this fit 4MATIC (All-Wheel Drive) models?
Engine mount fitment on the W212 varies significantly between Rear-Wheel Drive (Base) and 4MATIC models, as well as between 4-cylinder, V6, and V8 engines. This specific mount is typically designed for standard RWD configurations. Always verify your VIN before purchasing to ensure compatibility.
