OVERVIEW

Genuine Oil Drain Plug Sealing Washer

The N-013-850-3 Genuine VW/Audi oil drain plug washer renews the seal between the original drain plug and its mating surface on the specified V8 applications. The sealing ring is compressed by the correctly tightened plug to establish the fluid seal. This listing includes one washer; the drain plug and oil pan are separate.

Technical Details

  • Original part number: N-013-850-3.
  • Catalog dimensions: 24 mm inside diameter × 32 mm outside diameter.
  • Function: sealing washer for the matching engine oil drain plug.
  • Quantity supplied: one individual washer.
  • Match the original oil pan and drain plug before ordering.

The sealing diameter is important: a smaller or larger washer can sit incorrectly against the plug or oil pan. The 24 × 32 mm specification identifies this washer's seating dimensions; it is not the thread size of the drain plug. No unverified thickness or shipping weight is assigned to this Genuine part.

Common Reasons to Replace

  • The original washer has already been compressed during a previous oil service.
  • The sealing ring is distorted, scored, cracked or missing.
  • Oil seepage has been traced to the drain plug sealing faces.
  • A previous service installed an incorrect ring or reused a damaged washer.
  • The drain plug has been removed and its seal requires renewal.

Oil on the underside of the engine can come from several locations. Inspect the drain plug, sealing surface and surrounding components before assuming the washer is responsible. A replacement washer cannot repair damaged oil pan threads, a cracked sump or an incorrect plug.

Installation and Oil Service Notes

Follow the vehicle-specific oil service procedure. Remove the old washer, inspect the drain plug and sealing seat, and install the correct new ring. Tighten the plug to the workshop specification for the exact engine and oil pan. Overtightening can damage the threads or sealing surface and should not be used to compensate for a persistent leak.

Refill with the specified oil and verify the oil level using the applicable procedure. Inspect the serviced drain connection after operation. This is a sealing component rather than a substitute for damaged fastening hardware.

The Touareg application is restricted to the AXQ 4.2L engine, and the listed C6 A6 application is restricted to the BNK 4.2L engine. Engine displacement alone does not establish fitment: later engine versions and replacement oil pans must be checked against their original drain plug arrangement.
