Are you looking for a OBD2 scanner that is cheap, simple to use and shows all the live data and faults you need to diagnose your cars problems quickly?
We spend endless amounts of time researching different OBD2 readers trying to find the one fit for all cars. We end up with either a scanner that messes up the cars ECU causing more damage or one that doesn’t even connect to the car!
Carly is the product you been looking for, its is the most affordable OBD2 scanner out there that works well. I have personally used this scanner in my workshops and can say it’s the best scanner out there in its price range. Last week I failed a car on its MOT because the engine light was on. I quoted the customer for a diagnostic report, and they said they had ordered Carly for less than what I would charge to do the report. I was surprised, because we use the same Carly scanner.

What cars can Carly code and work on
I have used Carly with most cars and the OBD2 scanner is compatible with most car brands across the globe. If your car was built in 2001 or later, you can use the basic functions of Carly (engine check, emissions check, and live data) with your car model. This applies to both diesel and petrol cars.
How to setup and use Carly
It was time to get down to business once I downloaded the app and loaded the device in my hand. It’s a simple 3 step procedure to link Carly up to your vehicle:
- First you’ll need to connect the device to your car’s OBD2 port, which is usually beneath the dash near the steering wheel.
- Step two is to simply turn on the ignition in your car,
- Step three is to ensure that your phone’s Bluetooth is enabled. So far, everything has been pretty basic. The device was connected to the car and ready to roll in a matter of seconds. Depending on the diagnostic procedure you want to perform, you may have a few alternatives at the main page.
To test I selected the one just for SEAT. There was a pleasant surprise, though, because SEAT is part of the VAG, I also got access to VW, Skoda and Audi. You’ll need the app to work alongside the device, but that is free of charge and available to download from the App Store, or Google Play.

OBD2 Carly code scan feature
I used the device’s primary function, that of a code scan, for this assessment. The procedure was simple and easy, with results appearing almost instantly. I got five fault codes in total, one of which was the ABS warning light. If you want to clear the codes, you have the option to do so; however, if you subscribe, the app keeps track of the car’s history.

Furthermore, the Carly app colours each fault with a severity of “very bad,” “bad,” or “average.” As a result, it’s considerably simpler to understand the actual condition of each system and how much maintenance is required. Otherwise, you’d only get error codes but no indication on how much your car’s health has been affected.
