Parts for your 2020 Volkswagen Amarok-Spark plugs

2020 Volkswagen Amarok spark plugs — are they used?

The 2020 Volkswagen Amarok sold in Australia and New Zealand doesn’t use spark plugs. It runs diesel TDI engines (most commonly the 3.0‑litre V6 TDI, EA897 family), which rely on compression ignition rather than a spark. Diesel combustion is initiated by high compression and precise fuel injection, so spark plugs aren’t part of the system. Instead, these Amarok models use glow plugs to assist cold starts by warming the combustion chamber.

This design is confirmed across technical sources: the Volkswagen Owner’s Manual for Amarok (Model Year 2020, AU/NZ), Volkswagen Self‑Study Programme 512 covering the 3.0l V6 TDI (EA897), and the Volkswagen Electronic Parts Catalogue (ETKA) for 2020 Amarok list glow plugs and a glow plug control module, with no spark plugs specified. That’s why spark‑plug replacement doesn’t appear in the Amarok’s diesel service schedule.

For owners thinking about “spark plug servicing”, the right focus on a 2020 Amarok is the diesel starting and fuel systems. Glow plugs generally last a long time and are replaced as required rather than at fixed intervals. If cold starting gets rough, there’s excessive white smoke on start‑up, or the engine light flags a glow circuit fault, testing the glow plugs and control module is worthwhile.

• Have the glow system scanned for fault codes (for example, P0671–P0676 for individual glow plug circuits).
• Keep the battery healthy
