Get the manufacturer’s repair information for your 2025 Audi A4, including factory service procedures, diagnostics, technical illustrations, and wiring diagrams—in one digital manual made for your exact vehicle. Understand your vehicle. Approach repairs with confidence.

About the Audi A4

We list the A4 across five generations: B5, B6, B7, B8 and B9. Engines include the 1.8T, the 2.0 TFSI, the 3.0 V6 and TDI diesels, with front-wheel drive or quattro.

Made for your car, by VIN

The same model can differ by engine, transmission, body, and trim. That’s why we don’t sell a generic file: after payment, you give us your vehicle’s VIN, and we save the matching service information directly from the manufacturer’s official technical information website. You get the information that applies to your car—no guessing between years, engines, or versions.

Factory information you can put to work

Review repair procedures before starting a job (from routine maintenance to major repairs)
Understand component layouts with technical illustrations (procedures are explained step by step)
Follow electrical connections using wiring diagrams
Plan your work and discuss recommended repairs with your mechanic (or double-check a quote)

Illustrations and diagrams keep the original image quality supplied by the manufacturer. The PDF has bookmarks, an index, and working links, so you can go straight to the section you need.

Permanent ownership with no recurring subscription fees—the manual is yours to keep.

About the 2025 Audi A4

Your 2025 Audi A4 is from the A4 B9 generation, which covers model years 2017–2025. It is the last model year of this generation and includes the running changes made during production, which is why a manual for the exact year matters.

Check the model year on your VIN: on a 2025 vehicle the 10th character of the 17-digit VIN is “S”. Vehicles built for North America always carry the model year in that position; on some European or Australian vehicles it may be left unused, so in that case go by the registration papers or the build plate.

At 1 year old, a 2025 vehicle mostly needs scheduled maintenance, software and battery checks, and correct procedures for the newer electronic systems (ADAS sensors, calibrations and module programming).

Same generation: 2017 Audi A4, 2018 Audi A4, 2019 Audi A4, 2020 Audi A4, 2021 Audi A4, 2022 Audi A4, 2023 Audi A4, 2024 Audi A4.

All Audi A4 model years: 1995 · 1996 · 1997 · 1998 · 1999 · 2000 · 2001 · 2002 · 2003 · 2004 · 2005 · 2006 · 2007 · 2008 · 2009 · 2010 · 2011 · 2012 · 2013 · 2014 · 2015 · 2016 · 2017 · 2018 · 2019 · 2020 · 2021 · 2022 · 2023 · 2024 · 2025 · 2026
