OVERVIEW
Original combination bolt for the matched engine assembly
N-101-270-05 is a Genuine VW/Audi M6 x 55 combination bolt with an internal hex drive and a washer-style bearing arrangement. Its confirmed applications include specified intake hardware on the 3.2L R32 and TT and a separate charge-system fastening location on the Touareg Hybrid.
Correct length and head contact geometry matter at intake and charge-system attachments. This bolt is supplied individually; the throttle housing, intake manifold, charge pipe, seals and other mounting pieces are separate components.
Technical details
- Complete factory number: N-101-270-05.
- Factory specification: M6 x 55 mm internal-hex combination bolt.
- Design: Cylindrical socket head with washer-style bearing arrangement; match the complete original number and fastening point.
- Quantity supplied: one individual bolt.
The nominal M6 x 55 designation describes the thread diameter and fastener length. No unverified drive-bit size, strength class, thread pitch or tightening torque is assigned.
Common reasons to replace
- A rounded hex recess that prevents secure tool engagement.
- Damaged threads, a bent shank or a damaged bearing arrangement.
- A missing fastener or the wrong replacement length found during component service.
A vacuum leak, charge-system fault or throttle complaint is not proof of a bad bolt. Inspect the relevant gasket, housing, receiving thread and component seating before determining which parts require replacement.
Vehicle fitment
Match the engine and the fastening role in the table. The same bolt serves different assemblies; this is not a blanket fitment claim for all engine fasteners on these models.

Installation guidance
Position the component and its specified seal before starting the bolt. Start the thread by hand, maintain the original washer arrangement and use the factory tightening sequence for the exact housing or pipe joint.
Use a fully seated hex tool. Avoid over-tightening or adding locking compound unless the applicable repair procedure requires it, and complete the specified leak and operational checks after service.
