Frequently Asked Questions

Q: Will Carly work with my older car manufactured before 2008?
A: Yes, Carly supports vehicles manufactured from 1996 onwards with standard OBDII ports (16-pin connector). Most cars produced after 1996 have these ports, though some pre-2008 models may require adapter installation depending on their regional emissions standards.

Q: How long does it take to get the first diagnostic report after connecting my phone?
A: The initial connection typically takes less than 30 seconds for most vehicles. After establishing the Bluetooth connection, Carly scans for codes instantly and displays results within 5-10 seconds. For real-time data monitoring, you can start seeing live parameters as soon as the connection is established.

Q: Can Carly read codes from diesel vehicles or only gasoline cars?
A: Carly supports both gasoline and diesel engines, including hybrid and electric vehicles (OBDII equipped). The app’s comprehensive database contains diagnostic codes for virtually all vehicle types manufactured from 1996 onward with standard OBDII protocols, regardless of fuel type.

Q: Is there a limit to how many trouble codes I can store in the app?
A: Carly stores unlimited diagnostic history, with a maximum capacity of 10,000 codes in its database. The app automatically organizes recent and historical codes separately, allowing easy reference to past issues. You can also choose to archive data or export it via email/SMS to keep your smartphone storage free.

Q: Can I use Carly with my smartphone’s built-in Bluetooth or do I need an accessory?
A: Carly requires an OBDII Bluetooth adapter (sold separately) compatible with your smartphone’s Bluetooth version. While most modern smartphones have built-in Bluetooth, the Carly app communicates with an adapter that translates OBDII data into Bluetooth signals. This adapter connects to your car’s OBDII port and pairs wirelessly with your phone, making installation straightforward with no cables needed during operation.
