A Guide to Engine Mounts for the 2008-2014 BMW M3 (E90, E92, E93)
Eliminate engine vibrations and restore the smooth, responsive feel of your M3 by choosing the right replacement engine mounts.
- The hydraulic engine mounts on the E9x M3 are a common failure item; inspect them for leaks or collapse if you feel vibrations.
- For an OEM-quality replacement without the dealer price, choose Corteco, as they are the original manufacturer for BMW.
- Avoid budget brands like Anchor, DEA, and Westar, as they often increase vibration and fail prematurely on a high-performance car like the M3.
- Replacement is a moderately difficult DIY that requires supporting the engine and lowering the subframe; always replace mounts in pairs.
Is Your M3's Engine Mount Failing?
The engine mounts on the E9x M3 are a known wear item and can fail sooner than you might expect, sometimes in as little as 25,000-40,000 miles. Because they are filled with fluid, they can leak and collapse, leading to a number of clear symptoms. Ignoring these signs can lead to more stress on other parts like hoses and drivetrain components.
Common Failure Symptoms:
- Increased Vibration: The most common sign is a noticeable increase in vibration felt through the steering wheel, seats, and floor, especially at idle. 🎬 Watch: See common symptoms of a bad BMW engine mount
- Clunking or Banging Noises: You may hear impact noises from the engine bay when you accelerate, decelerate, or take sharp turns. This is the sound of the engine moving too much and hitting other parts.
- Visible Engine Movement: If you open the hood and have someone rev the engine slightly while in neutral, you might see the engine rock or shift excessively.
- Rubbing Marks on Skid Plate: A tell-tale sign specific to the E9x M3 is a rubbing mark on the aluminum undertray or skid plate. This happens when a collapsed driver-side mount allows the oil pan to make contact with the plate below it.
A Note on Recalls and TSBs
As of now, there are no specific recalls or Technical Service Bulletins (TSBs) from BMW or the NHTSA for engine mount failure on the 2008-2014 M3. This is considered a wear-and-tear issue, even though failures can occur at relatively low mileage.
Choosing the Right Aftermarket Engine Mount
When replacing your M3's engine mounts, you have a choice between OEM-quality parts and more budget-friendly options. For a high-performance vehicle like the M3, the quality of the mount makes a significant difference in ride quality and longevity.
Tier 1: OEM-Quality Aftermarket
Corteco: Corteco is the original equipment manufacturer (OEM) that supplies the engine mounts to BMW. Choosing Corteco means you are getting the exact same part that came on your car from the factory, without the dealership markup. For ride quality, vibration damping, and durability, Corteco is the best choice for an aftermarket replacement that maintains the original M3 feel.
Tier 2: Reputable Aftermarket & Reboxers
Vaico: Vaico is a known brand for European car parts, but there is less specific owner feedback for their M3 engine mounts compared to Corteco. They are generally considered a decent mid-tier option.
Beck Arnley: This brand is a "reboxer," meaning they source parts from various manufacturers and sell them under their own name. You might get an OEM-quality part, or you might get a lower-grade part. Due to this inconsistency, many owners report issues with increased vibration after installation. It's a gamble that may not be worth it for a sensitive car like the M3.
Tier 3: Budget Brands
Anchor, DEA, Westar: These brands are widely available and offer the lowest prices. However, they are known as budget options and forum users often report mixed results, including premature failure and significantly more vibration than OEM mounts. One M3 owner specifically reported Anchor mounts failing after only 30,000 miles. While they may save you money upfront, they are likely to compromise the refined feel of your M3 and may not last long.
Pro Tip: Always Replace in Pairs
Engine mounts should always be replaced in pairs. If one has failed, the other is not far behind. Replacing only one will put extra stress on both the new and the old mount, leading to another failure in the near future.

Frequently Asked Questions
Is it hard to replace the engine mounts on an M3?
It is a moderately difficult job. It requires an engine support brace to hold the engine from above while the front subframe is partially lowered to access the mounts. It is more complex than on a standard BMW and requires specific tools, but it is feasible for an experienced DIYer.
🎬 See this step-by-step DIY guide for replacing M3 mountsWhy are M3 engine mounts hydraulic?
Hydraulic (fluid-filled) mounts provide the best balance of performance and comfort. The fluid helps to dampen a wide range of engine vibrations, keeping the cabin quiet and smooth, which is a key characteristic of a BMW M car. Solid rubber or polyurethane mounts are stiffer but transmit much more noise and vibration.
Can I use stiffer, non-OEM mounts for better performance?
You can, but it's generally not recommended for a street-driven car. Upgraded polyurethane or solid mounts will transmit significantly more noise, vibration, and harshness (NVH) into the cabin. While they reduce engine movement, most owners find the trade-off in comfort to be too great for daily driving.
What is the OEM part number for the E9x M3 engine mount?
The most common OEM part number is 22112283798. You may also see part number 22112284817. 🎬 Watch: How to inspect and repair worn M3 engine mounts These parts are typically sold as a left/right pair and are identical for both sides.
