The ZF S5D320Z Transmission is known for its excellent quality, but is notorious for the failure of its shifter detents on old, higher mileage examples. This problem is most commonly identified by the shift lever's tendency to rest in front of the fifth gear gate while in neutral, or by difficulty selecting specific gears until the transmission is warm.

Genuine BMW Parts Online – Sourced from BMW Just Like the Original

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. Manufactured under the direction of BMW, expect excellent quality and a premium price since these parts are exclusively available through the BMW Dealership network. FCP Euro is proud to offer a full selection of Genuine BMW Parts online along with a comprehensive selection of other high quality replacement parts and accessories.

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, including a 1 year warranty. In fact, many of these manufacturers have been making parts for BMW for decades and are experts in their own right. In our industry these manufacturers are called OEM (Original Equipment Manufacturers) or OES (Original Equipment Suppliers), and are often brands you recognize including Hella, Bosch, Bilstein and Lemforder. Don’t be surprised to open that familiar blue Genuine BMW parts box and find a Lemforder branded part inside.

If you are looking to buy Genuine BMW Parts online then you’ve come to the right place. FCP Euro offers both types of product – Genuine BMW and OEM/OES - from brands we trust to use on our own cars. If you have any questions on what options are available to you, just give us a call at 877-634-0063, we are happy to help.

Genuine BMW Parts vs Aftermarket BMW parts

What’s the difference between Genuine BMW Parts and aftermarket? Genuine BMW parts are made to exact fitment and quality specifications to the vehicle. Although Aftermarket BMW parts may fit the vehicle, they may not be up to the same quality as the Original BMW Parts. If you are looking for the highest quality replacement parts for your vehicle then we recommend using Genuine BMW parts.

**Please note our returns policy as it pertains to Genuine BMW Parts: Only defective Genuine BMW parts can be returned for credit and only upon verification of the defect. Returns will be sent back to the Vehicle Manufacturer to be inspected, tested, and verified as ‘defective’ prior to a credit being issued. A VIN number, mileage installed, and mileage failed will be mandatory information needed for a Defective Genuine Part Return.
