TDI® Emissions System/AdBlue®

To get the most from your Audi Q7 TDI® ownership experience, you'll need to know a few things about AdBlue® and the TDI® emission system.

This ultra-low emission system is an advanced technology for the after-treatment of exhaust gases. In this final stage of treating the exhaust gas, the TDI system introduces a reducing agent known as AdBlue® into the gas flow. This reducing agent is critical to the proper operation of your Audi Q7 TDI®.

AdBlue® is stored in special holding tanks in your Audi Q7 TDI® and tanks must be topped-off by your authorized Audi Dealer at each scheduled maintenance interval. Because of this, you should always follow the scheduled maintenance intervals. Should driving style and/or conditions increase the usage of AdBlue®, additional AdBlue® may be necessary between scheduled maintenances intervals. Your understanding of AdBlue® and the TDI® emissions system will help ensure your driving pleasure and will help you get the most from your vehicle.
