Parts for your 2015 Volkswagen Amarok-Sump plug washers

2015 Volkswagen Amarok sump-plug-washers: what they do and when to replace them

Technical sources confirm the 2015 Volkswagen Amarok is fitted with a sump plug that uses a sealing washer. The Volkswagen factory workshop manual for Amarok 2.0 TDI engines (erWin/ELSA) specifies renewing the drain plug’s sealing washer at each oil change. Volkswagen’s parts catalogue (ETKA) lists a 14 mm sealing ring for the Amarok’s M14 drain plug (commonly referenced as an aluminium or copper crush washer, e.g., N 908 132 02). Major aftermarket catalogues in Australia and New Zealand also list 14 mm sump-plug-washers for 2011–2016 Amarok models, aligning with the factory documentation.

On the 2015 Amarok, the sump-plug-washer is a small but critical sealing component. It sits between the drain plug head and the sump, and it’s designed to deform slightly as the plug is tightened. That controlled “crush” creates a gas- and oil-tight seal, helping prevent weeps, drips, and dust ingress that can grime up the underbody. Because the washer work-hardens once crushed, it’s treated as a single-use item.

Best practice for servicing this Amarok is to replace the sump-plug-washer at every engine oil change. Reusing an old washer risks minor seepage that can smell, leave spots on the driveway, and mask other leaks later on. Owners should choose a quality aluminium or copper washer sized for the Amarok’s M14 plug, and avoid mixing sizes—too small won’t seat, too large won’t seal correctly. Where a drain plug with an integrated captive washer is supplied, the whole plug is replaced as an assembly.

Care tips that make the job easier and cleaner:

• Confirm washer size against the VIN or engine code and keep a couple of spares with the service kit.
• Clean the plug threads and sump face, removing old washer residue before refitting.
• Install a fresh washer and tighten the plug to the factory torque specification—no extra oomph with a breaker bar.
• After refill, run the engine, then check the plug area for any sign of a weep.
• Dispose of oil responsibly and note the next service interval on the vehicle’s records.

Aluminium washers are common on Volkswagen applications and seal well with the Amarok’s sump finish, copper options are also widely used and perfectly suitable when sized correctly. Whether aluminium or copper, the rule is the same: one service, one new washer.

Popular questions about 2015 Volkswagen Amarok sump-plug-washers

What size sump-plug-washer does a 2015 Amarok use?
Most 2015 Amarok 2.0 TDI models use an M14 drain plug with a 14 mm crush washer (Volkswagen ETKA lists a 14 mm sealing ring for this application). Because some variants differ by engine code and sump design, it’s smart to confirm by VIN before purchasing—or compare the new washer to the old one removed from the vehicle.

How often should the sump-plug-washer be replaced?
It should be replaced at every engine oil change. The washer is designed to crush once, reusing it can lead to minor oil seepage. The Volkswagen workshop manual calls for a new sealing washer on reinstallation of the drain plug.

Aluminium or copper—what’s better for the Amarok?
Both materials work well when correctly sized. Aluminium washers are commonly specified by Volkswagen for this platform and match the surface finish of the sump nicely. Copper washers are also suitable and popular in the trade. The key is using a quality 14 mm crush washer and tightening the plug to the factory torque.
