I've been driving a 2009 Audi A6L for several years and accidentally discovered several hidden features that are quite practical. Entering the engineering mode is easy: just hold down the CAR and SETUP buttons on the center console for about 5 seconds, and it will display vehicle diagnostic data, such as battery voltage and coolant temperature. This has helped me avoid battery drain issues. You can also customize settings, like turning the daytime running lights on/off or adjusting their brightness, which saves power and looks stylish. According to forum discussions, you can activate the mirror dipping function when reversing—manually adjust the mirror position while reversing, and the system will remember it for automatic operation. These features make the car smarter, and I often use them to check the vehicle's condition. However, avoid tampering with core settings to prevent malfunctions. Overall, exploring these hidden options has added convenience to my driving experience.
