OVERVIEW
Genuine VW/Audi rounded-head internal six-lobe bolt, part number N-103-352-06. This original M6 x 12 fastener has multiple factory uses. The applications below identify confirmed pipe, hose and engine-cover mounting positions using this exact part number.
Technical details
- Original part number: N-103-352-06 / N10335206.
- Published nominal size: M6 x 12.
- Rounded low-profile head with an internal six-lobe drive.
- Supplied individually for the specified attachment.
- Pipe, hose, bracket, seals, turbocharger and other hardware are separate.
The bolt retains the designated pipe, hose or cover attachment in its original position. The exact function depends on the factory mounting location. Correct mounting supports the intended routing and helps prevent an unsupported line from moving against surrounding components.
Match the original part number and location before ordering. A nominal M6 thread alone does not establish compatibility with another line fitting, bracket or engine attachment. Length and head form must suit the actual joint.
Common reasons to replace
Replace a missing fastener, damaged threads, stripped drive recess, visible deformation or corrosion affecting its condition. Renew the hardware when required by the applicable factory procedure after turbocharger or pipe service.
Inspect the mating threads, mounting tabs and routing whenever a line attachment is loose or has been damaged during removal. A bolt should seat normally without forcing the line into an incorrect position.
Oil or coolant leakage requires diagnosis of the actual line, connection and seal. A new mounting bolt does not repair a deteriorated hose, cracked pipe, damaged seal or defective turbocharger connection. Avoid excessive tightening as a response to a leak.
Installation and service notes
Allow the engine and turbocharger area to cool and follow the factory procedure for safe access. Handle oil or coolant system service as directed and protect exposed connections from contamination.
Identify the exact mounting position and compare the original fastener number before assembly. Position the pipe or line without strain, then start the correct bolt by hand into undamaged mating threads.
Use a correctly fitting six-lobe driver and the specified tightening sequence and torque for the actual attachment. Do not infer torque from the M6 x 12 size or transfer a value from a different engine joint.
Replace separate seals and other non-reusable components when required by the repair procedure. Use thread treatments only when specified. If the bolt will not seat normally, inspect the line alignment and mating threads before proceeding.
Complete the prescribed fluid-level, leak and routing checks after the repair. This listing supplies one original bolt, rather than a complete turbo line kit or replacement seal set.
