OVERVIEW

Genuine VW/Audi WHT-007-702 is an individual sealing ring for the assigned turbocharger oil-return line connection. It renews the specified seal when the original ring is damaged or removed during turbocharger or oil-line service on the confirmed TDI applications below.

Technical details and what is included

  • Factory part number: WHT-007-702 / WHT007702.
  • Component: turbocharger oil-return line O-ring.
  • Factory nominal sealing-ring designation: 17.12 × 2.62 mm.
  • Quantity supplied: one individual sealing ring.
  • Confirmed location: assigned oil-outlet/return tube joint on the listed 2015 TDI configurations.
  • The archive photo shows the individual ring and its central opening.

Match the original tube, seal groove and factory part assignment. The turbocharger uses separate seals at different oil and coolant connections. An oil-feed washer, a return flange gasket and this O-ring are separate repair parts even when shown in the same turbocharger diagram.

Common reasons to replace

  • The original ring is cut, pinched or otherwise damaged during removal.
  • Inspection finds deformation or deterioration that prevents correct seating.
  • Oil leakage is traced to the assigned sealing joint.
  • The factory procedure calls for a new ring when the return connection is opened.

Inspect the tube, sealing groove and mating surface before replacing the ring. A damaged tube, distorted flange or another leaking connection requires its own repair. Replacing this ring alone does not diagnose a turbocharger fault or correct an obstructed return line.

Vehicle fitment

The table covers the confirmed TDI oil-return application. Verify the installed engine and oil-line arrangement; different engines or sealing locations require separately specified parts.

Installation and service guidance

Follow the factory procedure for the exact turbocharger and oil-return tube. Allow the engine and exhaust to cool and complete the prescribed preparation before opening the connection.

Remove the old ring without damaging its groove. Inspect and clean the mating surfaces using the approved method, then use the factory-specified assembly lubrication where required. Seat the new ring in the correct location and avoid twisting, stretching or pinching it during assembly.

Renew other gaskets and fastening hardware when the repair procedure requires them. Use the specified sequence and tightening values for the tube and related components rather than applying a generic fastener torque.

Complete the required fluid-level and leak checks after service. This listing provides the sealing ring only; the turbocharger, oil line, other gaskets and engine oil are separate.
