OVERVIEW
Hollow factory fastener for the steering pressure pipe
N-021-074-8 is the Genuine VW/Audi banjo bolt for the assigned hydraulic power steering pressure pipe connection on the Volkswagen Phaeton applications below.
The cross-drilled hollow design allows hydraulic fluid to pass through the banjo fitting while the bolt secures the connection. A solid bolt or a visually similar banjo bolt with different passage geometry is not an equivalent replacement.
Technical details
- Complete factory number: N-021-074-8.
- Factory specification: factory banjo bolt N0210748; replacement for N0210747.
- Design: external hexagon head with hollow and cross-drilled fluid passages.
- Quantity supplied: one individual banjo bolt.
Select by the complete factory number and original pressure-pipe position. The sealing rings are separate service parts and must match the connection. The bolt does not include the hose or steering gear.
Common reasons to replace
- The sealing faces are damaged and cannot support a leak-free joint.
- Threads are damaged or cross-threaded.
- The hexagon is rounded or damaged.
- The fluid passages are damaged or blocked.
- The original bolt is missing or incorrect hardware was fitted.
Determine the source of a hydraulic leak before replacing the bolt. Inspect the banjo fitting, sealing rings, hose and receiver threads. A cracked pipe or damaged steering gear port requires its own repair.
Vehicle fitment
Match the assigned steering pressure pipe connection and original number. Other hydraulic connections on the same vehicle can use different bolts.

Installation guidance
Follow the vehicle-specific hydraulic steering procedure, including pressure relief and fluid-handling instructions. Keep all passages clean, fit new specified sealing rings and tighten the connection to the prescribed torque without twisting the pipe.
Use the approved hydraulic fluid and perform the specified bleeding and leak checks. Verify correct steering operation and fluid level after the repair.
