OVERVIEW
Restore the original 2.0T FSI crankcase ventilation connection
06F-103-215-B is the Genuine VW/Audi breather tube for the specified 2.0T FSI installations. The shaped metal tube connects the rear valve-cover ventilation outlet to the original intake-side connection, with flexible bellows sections and the factory flange arrangement.
The crankcase ventilation system relies on correctly sealed connections. Damage to the tube, bellows or connection can allow leakage that affects the intended ventilation path. Correct selection depends on engine code, production configuration and the complete breather-tube revision.
Technical details
- Complete factory number: 06F-103-215-B.
- Factory specification: factory rear valve-cover breather tube, revision B, for specified 2.0T FSI engines.
- Design: formed metal tube with flexible bellows, flange mount and original end connection, as pictured.
- Quantity supplied: one individual breather tube.
The individual tube is supplied. Valve cover, ventilation valve, gasket, fasteners and other hoses are separate. Confirm the installed breather configuration and use the specified new connection seal.
Common reasons to replace
- The flexible bellows are cracked or damaged.
- A diagnostic leak test identifies leakage at the tube or connection.
- The tube is bent or its mounting flange is damaged.
- The original connection is damaged during related engine service.
Inspect the valve-cover outlet, ventilation valve, adjoining hoses and connection seals. Poor idle or boost-related symptoms can have multiple causes; confirm the leak location and installed breather arrangement before replacing the tube.

Installation guidance
Follow the engine-specific breather-tube replacement procedure. Release the original connection correctly, protect the openings from contamination and renew the required flange seal. Fit the tube without twisting or stretching its bellows.
Check connection seating, hose routing and clearances, then perform the specified ventilation or intake leak check. Verify that any related diagnostic fault has been resolved.
