OVERVIEW
Genuine VW/Audi WHT-001-481 is an individual mounting bolt used at the assigned intake-system mounting points on the confirmed Audi engine configurations below. It provides the correct service fastener when original hardware is missing or damaged during engine work.
Technical details and what is included
- Factory part number: WHT-001-481 / WHT001481.
- Component: intake-system mounting bolt.
- Factory nominal designation: 6 × 16.
- Quantity supplied: one individual bolt.
- The archive photo shows the low-profile socket-drive head and threaded shank.
- Fitment depends on the assigned engine mounting point and factory engine PR code.
The nominal hardware designation is not a package dimension. Match the factory part number, original component and bolt position rather than selecting a replacement solely by diameter or head appearance. Different fasteners in the same intake-system diagram can have different functions and specifications.
Common reasons to replace
- The original bolt is missing during an intake-system repair.
- The socket-drive recess is damaged and prevents secure tool engagement.
- Damaged threads prevent proper installation at the assigned mounting point.
- The factory repair procedure specifies renewal of the particular fastener.
Inspect the mating threads and the component being secured before installing a replacement. Broken mounting features, damaged housings or incorrect assembly alignment require separate repair. Replacing this bolt alone does not diagnose an intake leak, a fuel-pressure fault or an engine warning.
Vehicle fitment
These profiles require the stated engine and original mounting point that specifies WHT001481. A matching vehicle model without the assigned engine or component does not establish compatibility.

Installation and service guidance
Use the factory procedure for the exact installed engine and intake-system component. Identify the assigned bolt location before removal and follow any required preparation for the surrounding engine work.
Inspect the mating threads and use the correct tool for the actual drive recess. Start the bolt correctly and follow the specified tightening sequence and torque. Do not substitute a generic fastener or estimate torque from the nominal diameter.
Replace separately specified seals, clips and neighboring hardware when the repair procedure requires them. Keep the component seated and aligned during installation rather than using the bolt to pull a misaligned assembly into position.
Perform the required inspection and operating checks after the repair. This listing supplies the individual bolt only; the intake assembly, hoses, fuel rail, brackets and fluids are separate.
