BMW Engine Block and Components diagram for 318i, 318is, 318ti, Z3

A harmonic balancer is a component of an engine that absorbs vibrations and minimizes resonance. A failing harmonic balancer can cause serious engine damage, so it's important to diagnose and repair it quickly.

• Engine vibration: A failing harmonic balancer can cause the engine to shake excessively, especially at high speeds
• Knocking noise: A knocking sound from the front of the engine can be an early sign of a separating outer ring
• Squeaking noise: A squeaking noise as the engine rotates could be a sign of a failing harmonic balancer

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
