This comprehensive scanning capability extends well beyond the engine and includes systems such as ABS, airbags, and transmission4.
The diagnostic interface presents information in an intuitive format, using a “traffic light” system to indicate the severity of detected issues. A green indication signifies minor or no errors, yellow indicates significant issues requiring attention soon, while red alerts signal immediate problems requiring emergency attention3. This simplified presentation makes complex vehicle diagnostics accessible even to users without technical expertise.
Additionally, the Smart Mechanic feature provides step-by-step repair guides and maintenance tips when fault codes are detected. This feature includes information about the fault code, its last occurrence mileage, potential consequences, and expert guidance on addressing the issue4. While this feature requires an additional subscription cost of approximately €36 per year, it provides valuable assistance for DIY maintenance and repairs4.
Using Carly for Audi coding and diagnostics can result in significant cost savings compared to dealer or workshop alternatives. Coding changes at a professional workshop can cost at least €30 per individual modification3. With Carly, users can make multiple customizations through the app at a fraction of the cost of professional services.
The device also helps prevent costly repairs by enabling early detection of potential issues. By providing access to comprehensive fault code information and maintenance data, Carly allows users to identify and address minor problems before they develop into major mechanical failures requiring expensive repairs3. For Audi A4 owners specifically, the ability to read error codes like P0420 (catalyst system effect too low) or P0300 (cylinder misfire) enables targeted troubleshooting and timely intervention2.
Service and maintenance functions further contribute to cost savings. The ability to reset service intervals after performing maintenance tasks like oil changes eliminates the need for workshop visits solely for service indicator resets4. This self-service capability extends the value proposition beyond mere diagnostics and coding.
Carly distinguishes itself through its straightforward and accessible user experience. The physical device is compact and simply plugs into the OBD2 port located under the steering wheel in most Audi models6. Once connected, it communicates with the companion smartphone app via Bluetooth, providing a seamless connection between the vehicle and the user’s mobile device3.
The app interface is designed to be intuitive, presenting complex vehicle data in accessible ways even for users without mechanical expertise. The diagnostic process is streamlined: users plug in the device, scan available vehicle systems, and receive a clear list of control units along with any fault codes and descriptions4. This simplicity makes Carly accessible to casual users while still providing depth for enthusiasts.
Furthermore, the coding interface is designed to be user-friendly, allowing customizations without requiring programming knowledge. Before making changes, Carly automatically creates a backup of the original settings, enabling users to easily revert to factory configurations if desired4. This safety feature provides peace of mind for users experimenting with different coding options.
Carly offers extensive compatibility across the Audi model range, making it a versatile option for owners of various vehicles from the brand. The system supports models including the A1, A2, A3, A4, A5, A6, A7, A8, Q2, Q3, Q5, Q7, Q8, TT, R8, and E-TRON5. This broad compatibility ensures that most Audi owners can benefit from the device’s capabilities.
However, it’s important to note that the exact features available vary depending on the specific model, build year, and software version. For example, the A1 (8X) model from 2010-2018 supports diagnostics, coding, used car check, service and oil reset, electronic parking brake adjustments (for models built 2012 or earlier), video while driving (depending on the headunit software), OBD diagnostics, and Digital Garage features5.
This model-specific functionality underscores the importance of checking compatibility before purchase, but it also demonstrates the system’s adaptability to various Audi vehicle configurations and generations.
For prospective buyers of pre-owned Audi vehicles, Carly offers valuable functionality through its Used Car Check feature. This capability analyzes the car’s ECUs to detect potential issues such as odometer fraud or hidden faults that might not be apparent during a visual inspection4. By comparing mileage data across different control units, the system can identify discrepancies that may indicate tampering—for example, if one control unit shows 80,000 kilometers while the speedometer displays 60,0004.
This feature has earned Carly a reputation as “a cheat sheet to buying a used car,” providing buyers with additional confidence when making purchasing decisions6. The ability to uncover hidden issues before purchase potentially saves buyers from expensive repairs and disappointment after acquisition.
Carly provides real-time monitoring capabilities through its Engine Live Data feature. This functionality gives owners access to live parameters from their engine’s ECUs, helping with performance monitoring and basic troubleshooting4. Users can view metrics such as RPM, coolant temperature, and other performance indicators in real-time, providing insights into engine behavior during operation.
