OVERVIEW
N-013-818-2 Genuine VW/Audi Sealing Washer. This individual sealing ring is used at the matching fluid-line connection during turbocharger service on the confirmed 2.7T applications below. The correct washer provides the sealing interface between the specified mating surfaces when the fitting is assembled and tightened according to the vehicle repair procedure. It is a small service part whose condition matters when disturbing a previously sealed connection.
Technical details
- Original part number: N-013-818-2 / N0138182.
- Published sealing washer size: 12 x 16 mm. Thickness and weight are not specified here.
- One individual washer supplied. Turbocharger, fluid lines, banjo bolts, fittings and additional sealing rings are not included.
- Included as a genuine sealing washer in a publicly documented Audi 2.7T turbo installation kit.
- The quantity needed depends on the connection being serviced. A complete turbo installation may require several different washer sizes; this listing supplies only this part number.
How it works
A sealing washer sits at the designated joint and helps close the leakage path between the fitting and its mating surface. The washer must match the original connection dimensions and sealing arrangement. It does not provide thread locking, repair a cracked line or replace a damaged fitting. Similar-looking rings used elsewhere on the same engine may have different dimensions or service requirements.
Common reasons to replace
Replace the matching washer when the service procedure requires renewal after opening the connection, when the original sealing ring is crushed, grooved or damaged, or when diagnosis identifies seepage at that specific joint. Turbocharger replacement, line removal and fitting service are common occasions to inspect and renew the required sealing hardware.
Fluid residue around a joint can also come from a leak above the fitting, a cracked line, damaged sealing faces, a loose connection or another component nearby. Identify the source before replacing parts. Reusing a damaged washer or fitting a ring of the wrong size may prevent the joint from sealing correctly even when the fastener appears tight.
Installation and service notes
Work with the engine cool and follow the applicable fluid-draining, access and cleaning instructions. Inspect the line and mating faces, remove the old ring completely and verify the replacement against the original part number. Keep debris out of open lines and install the correct number of washers in the positions specified by the repair manual. Do not stack extra washers to compensate for a damaged sealing surface.
Use the vehicle-specific tightening procedure for the associated fitting. After reassembly, restore any serviced fluid to the required specification and level, complete the required checks and inspect the connection for leakage. Confirm the VIN, engine, installed turbo lines and sealing position before ordering.
