OVERVIEW
Genuine M6 × 22 internal-multipoint mounting hardware
The N-106-136-01 Genuine VW/Audi mounting bolt secures the assigned turbocharger oil-return connection on the FSI applications below. A separate confirmed TT 225 hp application uses the same bolt in the secondary-air/vacuum bracket assembly. Its internal multipoint drive and combination seating arrangement match the assigned original fastener.
The return tube has different connections at its ends. Match this bolt to the oil-pan attachment and complete factory number rather than selecting hardware solely by vehicle model or apparent diameter.
Technical details
- Complete factory number: N-106-136-01.
- Nominal factory specification: M6 × 22.
- Design: socket-head bolt with internal multipoint drive and combination seating arrangement.
- Quantity supplied: one individual bolt.
The nominal specification describes the fastener itself rather than packaged shipping dimensions. Match the complete factory number, original attachment point and head seating arrangement. Similar-looking hardware elsewhere in the same assembly can differ in length, thread size or bearing surface.
Common reasons to replace
- A bolt is missing after component removal or previous service.
- The drive head is damaged or rounded.
- The threads have been crossed, stripped or otherwise damaged.
- The bolt is bent or its bearing surface no longer seats correctly.
- A previous repair used incorrect substitute hardware.
Inspect the return tube flange or bracket, receiving threads and any specified seal during service. An oil leak may come from a damaged seal, distorted tube or another nearby component; replacing the bolt alone does not establish or repair the cause.
Vehicle fitment
Match each row to its engine, body and component location. The FSI oil-return and TT secondary-air bracket applications are separate uses of this bolt; later TSI engines and other attachment points require individual confirmation.

Installation guidance
Allow the engine and turbocharger to cool. Keep the oil-return opening and tube clean, protect against contamination and follow the factory removal and installation procedure, including replacement of any seals specified by that procedure.
Align the mating components before engaging the bolt, start the threads carefully and use the correct tool for the actual drive. Follow the factory tightening instruction and sequence for the exact connection. Do not transfer torque values between different applications that happen to use the same bolt number.
Check that the return tube seats without strain and that nearby components are clear. Follow the prescribed post-service oil-level and leak checks after oil-line work. For the separate secondary-air bracket application, restore the bracket and hose routing and check clearance using that engine's procedure.
Ordering information
Supplied as one genuine bolt. Oil-return tube, seals, oil pan and a complete hardware kit are not included. Confirm the quantity required for the original connection.
