A useful tool depends on the jobs you want to do and the exact car you drive. Start with those details before comparing devices.

Write down your vehicle and task

Use the exact model, year, engine and market. Decide whether you need fault-code reading, live information or specific supported customisation functions. Support for one task does not establish support for another.

Check the official feature list

OBDeleven’s supported-vehicle checker helps you check its available functions. For Carly, review the scanner and app information for your car.

Compare the full cost

Check the hardware, app access, plan requirements and any credits needed for the features you want. Do not assume every feature is included with the scanner.

Read faults before changing anything

Keep a record of the codes and relevant symptoms. Clearing a code does not repair its cause. Ask a qualified technician when you are unsure about a fault or a coding change.

Plan your next step

Choose equipment for tasks within your ability, or contact a suitable specialist about your vehicle. Review sources and current business details before booking.
