What Is the Oil Filter Part Number for a 2015 Audi A3?

The most commonly specified genuine Audi/VW oil filter part number for a 2015 Audi A3 with the widely used 1.8T or 2.0T TFSI engines is 06L 115 562 (often written as 06L115562). However, the exact part number can vary based on engine code, fuel type, and market, so it is important to confirm it against your vehicle’s VIN and engine details.

Why the Exact Oil Filter Part Number Can Vary

The 2015 Audi A3 was sold worldwide with several different engines—petrol (gasoline), diesel, and in some markets hybrid or gas variants. Because of that, Audi uses different oil filters that look similar but are not always interchangeable. The part number above, 06L 115 562, applies primarily to the EA888-generation 1.8 TFSI and 2.0 TFSI engines that are common in North America and many other regions. Diesel models and some regional variants may use different filters.

The Common Oil Filter for 2015 Audi A3 Petrol (Gasoline) Models

For most 2015 Audi A3 petrol models equipped with the EA888-generation turbocharged four-cylinder engines, Audi and Volkswagen group documentation and dealer parts catalogs list 06L 115 562 as the standard spin-on oil filter.

Typical Engines Using 06L 115 562

The following description explains which engines in the 2015 A3 most commonly match the 06L 115 562 filter, based on publicly available parts catalog information and typical market configurations.

• 1.8 TFSI (EA888 Gen 3) – Common in many markets, especially U.S. and Canada; uses a spin-on oil filter of the 06L 115 562 type.
• 2.0 TFSI (EA888 Gen 3) – Found in performance-oriented trims and all-wheel-drive variants; typically specified with 06L 115 562.
• Some region-specific petrol A3 variants – Where they use EA888 Gen 3 architecture, they generally cross to the same filter specification.

In practice, if you own a 2015 Audi A3 with a 1.8T or 2.0T petrol engine, 06L 115 562 is usually the correct genuine filter, but it is still best practice to verify it using your exact engine code or VIN.

Alternative and Superseded Genuine Part Numbers

Over a model’s life, the Volkswagen Group sometimes supersedes part numbers or approves interchangeable versions from different suppliers. These alternatives often share dimensions and filtration specifications but may carry slightly different suffixes or codes in the catalog.

Common Variants and Notes

The list below outlines the kind of variations you may see in catalogs and how to interpret them.

• 06L 115 562 A / B / C – Letter suffixes commonly indicate a revision or supplier change; the core fitment is usually the same, but you should confirm compatibility.
• Supplier-branded equivalents – OEM suppliers (Mann, Mahle, Hengst, etc.) often list filters that cross-reference directly to 06L 115 562.
• Region-specific catalog entries – In some markets, the same physical filter may appear under a slightly different stock code tied to local logistics.

These variations do not generally change how the filter fits or functions, but because not all suffixes are universal, confirming against a current Audi/VW parts catalog or trusted supplier remains important.

Diesel and Other Engine Variants: Why They Differ

Not all 2015 Audi A3s share the same oil filter. Diesel TDI engines and some special variants use cartridge-style filters or different spin-on filters with different thread sizes, gasket diameters, and bypass valve specifications. Using a petrol filter like 06L 115 562 on a diesel engine is not appropriate and can cause poor filtration or leakage.

Examples of Non-Petrol Configurations

The following points explain, in general terms, which 2015 A3 versions tend to use different filters and why you cannot rely on a single part number for all cars.

• 2.0 TDI (Diesel) – Often uses a cartridge-style filter in a fixed housing; part numbers differ completely from 06L 115 562.
• 1.6 TDI (Diesel) – Also typically uses a cartridge filter; again, a separate part number family from the petrol engines.
• Regional special models or early-production variants – Some may have different housings or engines that call for distinct filters.

Because of these differences, owners of diesel or less common engine variants in the 2015 A3 lineup should never assume 06L 115 562 is correct and should instead check a VIN-based parts lookup.

How to Confirm the Correct Oil Filter for Your Specific 2015 Audi A3

While 06L 115 562 is the dominant answer for mainstream petrol versions of the 2015 A3, the safest approach is always to verify the part number for your exact car before ordering or performing maintenance.

Steps to Verify Fitment

The points below outline practical ways to confirm you are buying the correct oil filter for your specific vehicle configuration.

1. Check by VIN at an Audi dealer – Provide your Vehicle Identification Number to a dealer parts department; they can pull the exact part number tied to your engine code and build date.
2. Use an official or reputable online parts catalog – Many Audi/VW catalogs allow VIN or model/engine selection to list the correct oil filter.
3. Inspect the existing filter – If visible, the current filter may have the part number or a cross-reference printed on its body (though this assumes the last service used the correct part).
4. Cross-reference with OEM suppliers – Mann, Mahle, and other major suppliers list cross-reference tables keyed to 06L 115 562 and to specific Audi A3 engine codes.
5. Confirm engine type and fuel – Verify whether your car is 1.8 TFSI, 2.0 TFSI, 1.6 TDI, 2.0 TDI, or another variant; this is critical to avoid mixing diesel and petrol filters.

Following these steps helps ensure you obtain a filter that not only physically fits but also meets the correct pressure and filtration specifications for your engine.

Maintenance Considerations When Replacing the Oil Filter

Replacing the oil filter in a 2015 Audi A3 is typically done together with an oil change, and using the correct filter is only part of proper maintenance. Attention to torque, sealing surfaces, and oil specification all contribute to engine longevity.

Key Points for a Proper Oil and Filter Change

The following points summarize what owners and technicians should keep in mind when servicing the oil system on a 2015 A3.

• Use the right oil specification – Audi typically specifies VW 502 00 (for many petrol engines) or VW 504 00/507 00 for later and diesel engines; check your owner’s manual.
• Replace the drain plug washer or plug as specified – Some plugs are one-time use; reusing them can cause leaks.
• Lightly oil the new filter’s rubber gasket – For spin-on filters like 06L 115 562, a light film of fresh oil on the gasket helps ensure a proper seal.
• Tighten to specified torque – Over- or under-tightening the filter or drain plug can damage threads or cause seepage.
• Check for leaks after startup – Run the engine, then inspect around the filter and plug to confirm there are no leaks.

These basic procedures, combined with using the correct part number, help avoid common issues such as oil leaks, low oil pressure, or premature filter failure.

Summary

For most 2015 Audi A3 petrol models equipped with the 1.8 TFSI or 2.0 TFSI EA888 engines, the genuine Audi/VW oil filter part number is 06L 115 562, with some suffix variations possible. Diesel and certain regional variants of the 2015 A3 use different filters altogether, often cartridge-style units. Because of these variations, the most reliable approach is to confirm the correct filter by VIN or engine code through an Audi dealer or a reputable parts catalog before purchase or installation.
