Detailed Description

VAICO’s VAICO product line focuses on OE-style replacement parts for European vehicle systems, including emission control components such as crankcase ventilation hoses. This breather hose is specified for BMW 550i, BMW 650i, BMW 750i, BMW 750Li, and BMW X5 models listed with OE No. 11617540610, making it a practical service part when restoring crankcase ventilation routing and connection integrity. The V20-2598 designation helps technicians and parts buyers verify the correct hose during maintenance or repair.

Because crankcase ventilation hoses operate in a heat- and vapor-exposed environment, correct fitment and dimensions matter. The listed 500 mm length and 120 mm width support accurate replacement selection for the intended BMW applications.

This part cross-references OE-style part numbers 7 540 610 and 11 61 7 540 610 for the same application.

What It Helps Address

• Cracked or brittle crankcase breather hose material
• Oil vapor leakage at the ventilation hose connection

• Vacuum-related drivability issues tied to hose deterioration
• Emission control faults caused by a damaged breather hose

Installation Notes and Tips

Verify the OE number 11617540610 and compare the hose dimensions before installation. Inspect adjoining crankcase ventilation components, seals, and connection points for wear or contamination so the replacement hose seats correctly and maintains a secure path for vapor flow. Confirm the application against the vehicle’s model year and engine configuration before service.
