Engine Mount Replacement Guide for the 2001-2006 BMW 325Ci (E46)
Stop excessive engine vibration and restore your BMW's smooth performance by replacing worn engine mounts.
- Failing mounts cause heavy vibration and clunking noises; replace them to avoid damage to other components.
- For best results and longevity on a BMW, choose an OEM-equivalent brand like Corteco.
- Always replace engine mounts in pairs to ensure proper engine support and alignment.
- While DIY replacement is possible, it requires an engine support brace or jack and is moderately difficult.
Symptoms of Failing Engine Mounts
When the engine mounts on your 325Ci start to fail, the signs are usually noticeable. The most common symptom is a significant increase in vibration felt inside the car, especially at idle, through the steering wheel, or in the seats. You might also hear clunking or banging noises from the engine bay when you accelerate, decelerate, or shift gears. In severe cases, you might see the engine visibly moving or sagging in the engine bay if you have someone rev the engine while you watch. A failed mount can even cause a rough idle that feels like a misfire.
Don't Ignore Bad Mounts
Driving with completely failed engine mounts is not recommended. Excessive engine movement can put stress on coolant hoses, power steering lines, and electrical wiring, potentially leading to more expensive repairs. It can also make the car feel unstable, especially in turns.
Choosing the Right Aftermarket Engine Mount
When shopping for new aftermarket engine mounts for your E46 325Ci, you'll find several brands with different levels of quality and price. It's important to replace mounts in pairs to ensure even support and prevent premature failure of a new mount.
Brand Quality Tiers
- OEM-Equivalent (Best Quality): Brands like Corteco are often the original equipment manufacturer (OEM) for BMW. This means their aftermarket parts are virtually identical to the genuine BMW parts, offering the best fit and performance without the dealership price tag. Choosing Corteco is the safest bet for restoring the original ride quality.
- Reputable Aftermarket (Good Quality): Beck Arnley focuses on parts for imported vehicles and aims to match original factory specifications. While they sometimes re-box parts from other manufacturers, they generally offer a quality product that is a good alternative to OEM.
- Standard/Budget Aftermarket (Varying Quality): Brands like Anchor, URO Parts, Westar, and DEA offer more budget-friendly options. Owner experiences with these brands are mixed. Some find them to be a perfectly adequate and affordable solution, while others report issues with vibration, fitment, or premature failure. URO Parts can be a viable budget choice, but for a critical part like an engine mount on a BMW, investing in a higher-tier brand is often recommended to avoid doing the job twice.
A Note on Upgrades
You may see "solid" or "polyurethane" engine mounts advertised. These are designed for track or high-performance use and will transfer significantly more vibration into the cabin. For a daily driven 325Ci, stick with high-quality hydraulic mounts to maintain comfort.

Frequently Asked Questions
Do I need to replace both engine mounts at the same time?
Yes. Engine mounts wear out at a similar rate. If one has failed, the other is likely not far behind. Replacing them in pairs ensures the engine is properly balanced and saves you from having to do the job again soon.
Are there any recalls for the 2001-2006 BMW 325Ci engine mounts?
No, there are no recalls or common Technical Service Bulletins (TSBs) issued by the NHTSA or BMW specifically for engine mount failure on the 2001-2006 325Ci. This is a standard wear-and-tear item.
How difficult is it to replace the engine mounts myself?
This is a moderately difficult job for a DIY mechanic. It requires safely supporting the engine with a jack or engine brace while you unbolt the old mounts and install the new ones. Access can be tight, but it can be done with a good set of tools and patience.
What are the OEM part numbers for the 325Ci engine mounts?
The engine mounts are typically side-specific. The common OEM part number for the left and right mounts is 22116779970. However, always verify the exact part numbers for your specific vehicle, such as the left bracket (22111094697) and right bracket (22111094694), if you are replacing those as well.
