Detailed Description

Febi 103923 is an engine oil filler cap built for vehicles that use a 74 mm round cap with gasket sealing. It is listed for numerous BMW and Mini models, including BMW 230i, 530i, M240i, X1, X3, X5, X6, M5, and Mini Cooper applications across model years 2006 through 2021. This part cross-references OE numbers such as 11 12 4 737 102 and 11 12 7 560 481 for the same application.

What It Helps Fix

• Oil cap that no longer seals properly
• Missing or damaged engine oil filler cap
• Oil vapor leakage around the filler opening
• Contamination entering the oil fill area
• Loose fitment at the valve cover oil fill neck

Installation Notes and Tips

Verify the cap style, outer diameter, and gasket requirement before installation. Confirm the vehicle application against the listed fitment for your BMW or Mini model, since this part is used across multiple engine platforms and model years. Clean the oil fill opening before installing the cap to help the gasket seat evenly.
