Audi's Emissions Software: The Recall That Could Affect Your Car

Wouter Smit · 2026-10-26

Audi is recalling 149,155 A4, A5, A6, and Q5 vehicles built between July 2007 and August 2012. These cars have V6 TDI diesel engines, and the problem is with the emissions software. Specifically, the exhaust gas recirculation (EGR) system reduces its activity based on outside temperature. That might sound like a minor detail, but it means the cars don't meet Regulation (EC) No 715/2007 and recent rulings from the Court of Justice of the European Union. Now, if you're in the US, you might think this doesn't concern you. But recall checks are important no matter where you live. And if you drive one of these models, you'll want to know what's going on. ### What's the issue with the EGR? The EGR system sends a portion of exhaust gas back into the engine to reduce nitrogen oxide (NOx) emissions. In these Audis, the system dials back the EGR flow when it's cold outside. That's a problem because NOx emissions go up. The EU regulation sets limits on NOx, and this temperature-based reduction violates those limits. Audi says it's a software issue, and the fix is a software update. ### Why should you care? If you own one of these cars, you might get a recall notice in the mail. But don't wait for it. You can check for recalls yourself using your Vehicle Identification Number (VIN). It's free and takes just a few minutes. And even if you don't own an Audi, it's a good habit to check your car's recall status regularly. Recalls happen all the time, and they're not just for older cars. ### How to check for recalls There are several ways to check for recalls in the US. The National Highway Traffic Safety Administration (NHTSA) has a free tool on its website. Just enter your VIN and you'll see if there are any open recalls. You can also sign up for recall alerts from NHTSA or check with your dealer. Some third-party services also offer recall checks, but stick with official sources for the most accurate info. ### What about the Audi recall specifically? Audi will notify owners, and dealers will update the software. The recall is expected to start in the coming months. If you have questions, contact Audi customer service or your local dealer. And remember, recalls are always free – you shouldn't pay a dime for the fix. ### The bigger picture This recall is part of a larger push to clean up diesel emissions. It's a reminder that software can have a real impact on how clean a car runs. And for drivers, it's a nudge to stay informed. After all, your car's recall status is just a VIN check away.
