Audi Genuine Engine Oil Drain Plug Washer - N0138495

Function and Usage:

Its primary application is to seal the engine oil drain plug to the oil pan to prevent oil leaks between oil changes. Because it is a crush washer designed for a single-use compression seal, Audi and VW technical guidelines specify that it cannot be reused or reinstalled and should be replaced every time you perform an oil change.

Alternative/Secondary Applications:

Depending on the specific vehicle model and engine configuration, this exact 14x20mm washer is also utilized as a sealing element in other fluid assemblies, including:

• Power steering pressure lines and return hose connections

• Water pump assembly components

Fitment:

This is an incredibly common hardware piece across the entire Volkswagen Group lineup, utilized across multiple generations of Audi, VW, Porsche, and Lamborghini vehicles (ranging from older 1.8T and VR6 platforms up to modern engines like the 2.5T in the RS3/TT RS and the 3.0T/2.9T V6 variants).

Note: This part directly replaces the older part number N0138494.
