❌ Cons

Often, garages don’t clear error messages even though they fixed the issue, so Carly may pick up a bunch of error codes left in the system.
The pricing is a bit odd too.
The range of features available for coding can vary depending on the make and model of your car.
Away from the scanner itself, if you begin exploring the Carly app, you’re unfortunately met with a few issues.
There are certain settings or options in the car that it cannot change. For instance, some advanced settings or manufacturer-specific features may not be accessible through the app.
As with any fault code reader, you’ll likely be alarmed by the number of errors that come back upon a scan.
The cost might seem steep to some.
It is quite annoying when you have to wait for up to ten minutes to generate a diagnosis on a car.
I had a problem connecting to my Fiat Panda.
It only works if you have a ODBII port available.
It can’t do all tasks for all cars.
App can get expensive.
The weirdest issue is on the car selector menu: the Audi RS2 was apparently built between 2000 and 2005. Hmmm.
Our little i3 came back as ‘Very Bad’, the main red issue is with the infotainment system. Having a fault with the infotainment system will never be a major or ‘very bad’ issue that stops your car from properly functioning.
You could spend money repairing something that isn’t entirely needed.
There is ongoing subscription fee for premium features.
The Carly licenses are an annual subscription.

Review Summaries
Considering how much data Carly provides and the savings you can achieve by fixing smaller issues in your vehicle yourself, you might think it costs thousands of pounds. It doesn’t. You can buy the Scanner only for £74.80, which gives access to full OBD features, including OBD level diagnostics, OBD level parameters, and the emissions check.
In conclusion, the Carly OBD Scanner is a remarkable, comprehensive car diagnostic and maintenance tool. It amalgamates advanced technology, ease of use, and extensive features to provide an all-in-one solution for car owners and enthusiasts.
The Carly scanner is a brilliant bit of kit that consists of a small plastic dongle-type device, which plugs into the ODBII port of your vehicle. It’s complimented by a fantastic app, which allows you to read, diagnose and clear fault codes that might come up when you carry out a scan. It’s powerful too, so not only can it pinpoint any issues, Thanks to a growing suite of features found within the app, Carly provides a lot of information for what is a relatively small initial outlay and ongoing subscription fee.
By extending what an OBD scanner can do, Carly is a cinch to use while also being able to help with maintenance, repair and used car advice. Unfortunately it isn’t suitable for every vehicle.
Carly is a car diagnostic tool that connects to your smartphone and provides insights into your vehicle’s health1. It offers features such as diagnostics, coding, battery check, and used car check23. The tool is easy to use, accurate, and customizable, but it also has some limitations and costs.
Carly can be a helpful car diagnostic tool which can potentially save you money if you DIY when it comes to fixes. It’s not perfect, as it could send you on a wild goose chase or inform you about faults that really don’t matter. It also has limitations, such as needing a subscription to access some features, compatibility issues with some car models, and the risk of voiding your warranty if you modify certain settings via coding. However, these are minor drawbacks compared to the benefits of Carly if it ends up saving you an expensive trip to a workshop.
I think Carly is pretty good value for money. Yes, there are much cheaper fault code readers, but this is one of the few that can give you manufacturer-level diagnostics, and that Smart Mechanic feature could be a godsend one day.
A pocket-sized catalyst for preventative maintenance but a couple of small quirks in the app stop it from being perfect.
It’s early days, and I’m yet to explore the full features of Carly, but so far, so good. The simplicity of the app is very positive and the lack of faff makes DIY diagnostics easy. At this stage there’s very little I can honestly grumble about. Having said that, I would like the option to be able to pay monthly instead of having to pay the year’s subscription upfront.
