Parts for your 2015 Volkswagen Amarok-Oil cap

2015 Volkswagen Amarok Oil Cap — Purpose, care and when to replace

The 2015 Volkswagen Amarok is fitted with an engine oil filler cap. This is shown in Volkswagen’s own service literature (ELSA/repair manuals), the ETKA parts catalogue, and the 2015 Amarok owner’s manual, which all depict the oil cap on the top of the engine/rocker cover with the standard oil-can symbol. So yes, the oil-cap is relevant and used on the 2015 Amarok.

On the Amarok’s 2.0 TDI/BiTDI engines, the oil cap does more than just plug a hole. It seals the filler neck to keep dust, water, and road grime out of the engine, and it helps maintain correct crankcase ventilation behaviour. A healthy cap stops oil mist from weeping onto the rocker cover and prevents pressure or vacuum leaks that can affect idle quality and overall engine cleanliness. It’s a simple part with a big job.

Over time, the cap’s rubber seal (O-ring) can harden, flatten, or crack. When that happens, owners might notice a faint oily smell after a drive, a light sheen of oil around the filler area, or residue collecting on the plastic engine cover. In worse cases—like a forgotten or loose cap—oil can splash out, making a mess under the bonnet and contaminating the engine bay. None of that’s ideal on a hard‑working ute like an Amarok.

As part of routine servicing, the oil cap deserves a quick once‑over. Good workshops and home mechanics alike should:

• Inspect the cap’s O‑ring for nicks, flattening, or brittleness.
• Wipe the filler neck and seating surface clean before refitting.
• Refit the cap until it seats positively
