There isn’t a single oil filter number for every 2018 Audi A4; the correct cartridge or spin-on filter depends on the engine installed. The most reliable way to determine the correct part number is to identify your engine code (or VIN) and cross-check Audi’s official parts catalog.
In this article, we outline how to identify the correct oil filter, show the typical engine variants used in the 2018 A4, and provide steps to source the right filter from dealers or aftermarket suppliers.
Engine options in the 2018 Audi A4
Before listing specific engines, it’s important to note that the 2018 A4 lineup uses several engine configurations depending on market. The oil filter cartridge or canister you need is tied to the engine code, not the car model year alone.
- 2.0 L turbocharged petrol (EA888 Gen 3) — commonly found in many markets as the base gasoline option.
- 2.0 L turbocharged diesel (EA288) — used in many markets for efficiency and torque.
- 3.0 L turbo diesel (EA897) — available in higher-end trims or certain regions.
The exact part number will correspond to the engine code, so this list is only to give a sense of the most common powertrains that require different oil filters.
How to identify the correct oil filter part number
To ensure you order the right filter, follow these steps to verify the exact part number for your A4’s engine:
- Locate your engine code on the engine block or in the vehicle’s service documentation. Common places include the engine cover, near the intake manifold, or in the vehicle’s VIN information plate.
- Check your owner’s manual or the service booklet for the recommended filter type (cartridge vs. canister) and its OEM number range.
- Use Audi’s official ETKA parts catalog, or an authorized parts retailer’s cross-reference tool, by entering the engine code or VIN to pull the exact oil filter part number.
- Confirm the filter’s compatibility with your current maintenance interval and whether your car uses a cartridge or a canister type in the 2018 A4.
- Consider buying from a reputable supplier that provides cross-reference validation and packaging that matches your car’s specification.
Following these steps ensures you get the correct oil filter for your engine variant and avoids misordering.
Where to buy the right oil filter
When you know the exact part number, you have several solid options to purchase:
- Authorized Audi dealer parts departments, which will have the exact OEM filter for your engine code.
- Official Audi parts retailers and the Audi genuine parts catalog online.
- Independent auto parts stores that support cross-referencing by engine code or VIN.
- Reputable online marketplaces with filter cross-reference tools and customer reviews.
Always verify the listing against your engine code to avoid ordering the wrong filter, and check compatibility notes for your specific A4 model year and market.
