2. Carly Diagnosis is supported for my car, but it's not working. What should I do next?
If Carly Diagnostics doesn't work for the supported car models, please make sure that all these conditions are fulfilled:
- Make sure that you use the latest version of the app
- Make sure that you have unlocked the Carly Features in the app. The manufacturer-specific faults are only displayed with the Carly license.
- Make sure that Bluetooth is enabled on your smartphone.
- Make sure that location permissions are accepted.
- Make sure that you have chosen the exact vehicle model in the app manually.
- Start the engine and click on "Connect"
- If the internet connection is interrupted, please reinstall the app and restart your smartphone
- Now check if there is a connection between the scanner and the vehicle
3. I followed the steps above, but still cannot use Carly Diagnostics. What can I do now?
Please check if any of the following situations occur:
- A message appears stating that it cannot connect to the Smart Mechanic server.
- A message appears indicating that the ECU cannot be found.
If one or more of the above applies to you, we’ll investigate further to provide a suitable solution.
In that case, please fill out the support form. Providing this information in advance helps us offer faster and more accurate assistance. We appreciate your cooperation.
Please be aware that Carly diagnostics also involve the following considerations.
- If you have installed additional car parts yourself, Carly Diagnostics might be blocked.
- For the VW, Audi, Skoda and Seat/Cupra, the build year of your car plays a big role. For certain vehicles of this group, manufacturer-specific fault codes can only be recognized for specific ECUs.
- For Mercedes models, we support Carly Diagnostics for a build year starting around 2005.
- For Mercedes models between 2001 - 2004, currently, we only offer the Basic On-Board Diagnostics (OBD)
4. Carly Diagnosis is not supported for my car. What can I do?

Every car is unique and may have a different ECU installed based on the model and build year. If the information here does not resolve your Diagnostics issue, please fill out the support form here. Our support team will get in touch with you as soon as possible.
