There isn't a universal oil filter part number for all Audi S4 models—the correct number depends on your engine code and year.
Across its generations, the S4 has used several engines and filter designs, with part numbers published in Audi's OEM catalog (ETKA) and dealer databases. To be sure you're ordering the right filter, identify your engine code and model year, then reference a current parts catalog or confirm with an Audi dealer or independent shop.
How to determine the exact oil filter part number for your S4
Use these steps to verify the exact filter grade and part number for your car.
- Identify the engine code and model year from the owner's manual or the data sticker on the engine bay or vehicle information plate.
- Use the VIN to search in official catalogs (ETKA, EPC) or reputable parts websites that offer VIN-based lookup.
- Check the existing filter's markings: many filters have the part number printed on the outer canister or the filter element; if you remove the old filter, note the codes.
- Confirm the filter type: some S4 generations use cartridge-style filters inside a housing, others use spin-on filters; the type determines the compatible part number.
- When in doubt, contact a dealership or a trusted independent shop with your VIN and engine code to verify.
By verifying the engine code, year, and using official catalogs, you can confidently order the correct oil filter for your Audi S4.
Where to source the correct filter and cross-reference
These sources help you confirm compatibility and find cross-references for aftermarket filters.
- Audi Genuine Parts catalog and dealer parts departments for the most reliable match to your VIN.
- Official OEM catalogs such as ETKA/EPC (often accessible via a dealer or authorized workshop) to look up by engine code and year.
- Reputable auto parts retailers that offer VIN-based or engine-code-based search and cross-reference capabilities.
- Local Audi service centers or experienced independent mechanics who can confirm fitment and install the correct filter kit.
Always double-check compatibility with your vehicle’s VIN and engine code to avoid ordering the wrong part.
Summary
The oil filter number for the Audi S4 is not universal; it varies by engine and model year. To ensure you get the right part, identify the engine code and year, consult OEM catalogs (ETKA/EPC) or your dealer, and cross-check with the filter housing markings or the old filter. If unsure, consult a qualified technician with your VIN for confirmation.
