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, low cranking voltage can mimic glow plug issues.
• Replace the diesel fuel filter on schedule and use quality diesel to protect injectors and help clean starts.
• If a glow plug is faulty, replace it promptly to avoid hard starts and extra soot on cold mornings.

Note for edge cases: while Amarok models in some regions and years have had petrol engines that do use spark plugs, the 2020 Amarok range for AU/NZ is diesel only. If a grey‑import petrol Amarok is in play, the VIN/engine code will confirm it, and then standard petrol spark‑plug servicing applies per the relevant owner’s manual.

Technical sources referenced: Volkswagen Owner’s Manual — Amarok MY2020 (AU/NZ market), Volkswagen Self‑Study Programme 512 — The 3.0l V6 TDI Engine (EA897), Volkswagen Electronic Parts Catalogue (ETKA) entries for 2020 Amarok, which list glow plugs and associated control components, not spark plugs.

Popular questions about 2020 Volkswagen Amarok spark plugs

Does a 2020 Volkswagen Amarok have spark plugs?
The 2020 Amarok in Australia and New Zealand does not have spark plugs. It uses diesel TDI engines that rely on compression ignition and employ glow plugs for cold starts instead of spark plugs.

What should be serviced instead of spark plugs on a 2020 Amarok?
Focus on the glow plugs and glow plug control module when cold starts are rough, alongside routine items like the diesel fuel filter and battery. Glow plugs are typically replaced only when faulty, rather than at a fixed kilometre interval.

Are there any Amarok models that do use spark plugs?
Some Amarok variants in other markets and earlier years were fitted with petrol engines that use spark plugs. However, the 2020 Amarok models sold new in AU/NZ are diesel only. If unsure, check the VIN and engine code to confirm the engine type.
