Common Repair Symptoms

• Cracked or brittle crankcase breather hose

• Check engine light related to crankcase ventilation or emission flow issues
• Damaged hose routing from heat, age, or vibration

Installation Notes and Tips

Verify the hose routing from the oil separator to the dipstick before installation and compare the end styles to the original part. The molded shape, clip-on end, and push-in end are important for correct alignment on BMW crankcase ventilation systems. Inspect nearby connectors and seals for wear, since a damaged mating component can affect the repair. Confirm vehicle build date where noted in the fitment data, including 2006 BMW 330i built September 2005 and older, and 1998 BMW Z3 built September 1 and newer.
