Company details
Written by the company
Carly — OBD2 car scanner Founded in 2014 in Munich, Germany, Carly is an automotive tech company that connects drivers with the information hidden inside their cars. Carly provides simple solutions throughout the lifecycle of car ownership, delivering peace of mind and empowering you to save time and money. Our mission is to be a reliable companion for drivers that delivers powerful data and valuable insights. Unleash your inner car hero with Carly! The Carly OBD2 Diagnostic Scanner was named 'Runner Up for Tech Product of the Year ' at the prestigious Parker's Product Awards. It got Highly Recommended for "makes the process more accessible for home users." In 2025, described by the Products Writer and tester for CAR and Parkers, Aaron Hussain, as "Score: 4/5. A pocket-sized catalyst for preventative maintenance, but a couple of small quirks in the app stop it from being perfect."
Our Origins
Written by the company
- An $8,000 repair estimate. An $80 fix.
- One of Carly’s founders was told his car needed repairs costing nearly $8,000—more than the car was worth. Like most drivers, he had no way of knowing whether the diagnosis was accurate. Instead of accepting the bill, he dug deeper. By accessing the car’s hidden data, he uncovered the real issue: a small component that cost just $80 to replace. The problem wasn't the car. It was the lack of transparency. Today, Carly gives drivers direct access to their vehicle's data, helping them understand issues, avoid unnecessary repairs, and make smarter decisions about their cars. That's how Carly was born.

It’s just incredibly expensive……
It’s just incredibly expensive for what you get, as a home user to use it maybe once or twice a year is scandalous. There are better alternatives with a one off purchase model less than the cost of a year. The whole built in mechanic, everyone can use Google so don’t be fooled into thinking that’s worthwhile.

We’re sorry that Carly feels too expensive for your needs as a home user, especially if you only plan to use it once or twice a year. We understand that a yearly license may not feel worthwhile for every customer.
Carly is offered as an annual app license that provides access to the available Carly functions, diagnostics, and supporting repair and maintenance information during the license period. We know that some users prefer a one-time purchase model, and your feedback is important for how we communicate the value of Carly for different usage needs.
Thank you for sharing this clearly. It helps us improve how we explain the license model, included features, and who Carly may be the right fit for before purchase.
Slow fault code reading/deleting. Phone gets hot…
Did not want to read fault codes on one of my cars, support could not help me make it work, but offered money back. It works on my other cars so i dont want a refund.
It takes very long for the app to read the fault codes, and my phone (brand new iPhone 17 Pro Max) gets very hot when reading or deleting fault codes. Does not make sense that an app like this should demand that much processing power. Other than that it works pretty much as intended, but just takes so long to read and delete codes.

Thanks for sharing your thoughts. We’re sorry that your experience didn’t meet your expectations and that you feel the price didn’t provide the value you hoped for. We strive to offer as much information as possible on our website to help customers make informed decisions and set clear expectations.
At the same time, we understand some customers might prefer different offers or products that better suit their needs. We truly appreciate the chance you gave Carly and are sorry to see you go.

The Carly setup didn’t work at all and awaiting refund for more than a month. All they do is keep asking same questions again and again via their tickets.
Screenshots to logs all provided and they don’t bother as long as you bought it. Please also note they have an auto renewal and no customer service whatsoever. Please refrain from buying Carly. BimmerCode is much more reliable and offer better service.

We’re sorry that the Carly setup did not work for you and that your refund request has remained unresolved for more than a month. We understand how frustrating it is to provide screenshots and logs, but still feel that the same questions are being repeated without clear progress.
Because this involves a technical setup issue, a refund request, and your previous support communication, we cannot review the case details publicly on Trustpilot. Please open a new ticket here: https://support.mycarly.com/hc/requests/new?ticket_form_id=360000444960

We’re sorry that Carly did not work as expected for you. We understand how disappointing it is when you try to use the app and it does not deliver the result you need.
Carly’s available features can depend on the vehicle brand, model, year, installed control units, and software version. That means a vehicle may be generally supported while certain diagnostics or features may behave differently depending on the exact vehicle configuration.
Our support team can review your case more closely and check what happened with your setup. Please contact us through Carly Support and avoid sharing any personal data publicly here.

We apologize that your vehicle isn’t fully supported at this time. Feature availability varies depending on the brand, model, and year, and we are continuously working to expand coverage. You can visit our support page to see if your car's brand and model are listed. Each supported brand has its own page with all compatible models and manufacturing years included. We look forward to supporting your vehicle soon and regaining your trust.

We’re sorry that Carly did not provide the level of guidance you expected compared to your Autel scanner. We understand that everyone’s needs are different, especially when looking for detailed diagnostic direction. It’s sad to see you go, and we regret that Carly was not the right fit for you.
Not good
Not good! Paid for one year and the unit was gift! Couldn’t scan any of my cars as been told need to pay to show the errors! Absolutely waste of time and money

Reply from Carly Solutions GmbH
We’re sorry that Carly did not meet your expectations, especially after receiving the adapter as a gift and then finding that the functions you wanted required an active Carly license.
Carly is offered as an annual app license, which unlocks the digital functions in the Carly App. The adapter enables the connection to the vehicle, while access to advanced features such as detailed diagnostics can depend on the selected license and the available functions for the specific vehicle.
The available Carly functions can also vary by brand, model, year, installed control units, and vehicle software. We understand that this needs to be clear before use, and your feedback helps us improve how we explain the difference between the adapter, the license, and vehicle-specific feature availability.

We’re sorry that Carly only felt useful for basic fault codes. Available functions can vary depending on the exact model, year, equipment, software, and installed control units. We understand how disappointing this is when you expected more value from the product, and we regret that Carly did not meet your expectations.

Thank you for your feedback. We’re sorry the product didn’t meet your expectations. We know that sometimes things don’t work perfectly for everyone, especially when it comes to different vehicles or specific situations. We encourage everyone to take a close look at the compatibility details on our website before making a purchase.
If there’s anything we can do to help or clarify, please don’t hesitate to reach out.
Subscription trap
Nothing available if you don't subscribe.
You've bought a device, you first plug it on a recent car, recently checked, many errors and problems discovered. None of them really tells anything. If you want to know more... subscribe.
The ad suggests you can save bucks with this. But in reality, you need to pay once more... every month.

We’re sorry that your first experience with Carly felt limited after buying the adapter, especially when you expected clearer diagnostic information without needing an active license.
Carly is offered as an annual app license that unlocks the digital functions in the Carly App. Without an active Carly license, only basic OBD standard functions are available. Manufacturer-specific diagnostics, detailed fault code information, and further vehicle-specific Carly functions are part of the digital license.
The available Carly functions can also depend on the vehicle brand, model, year, installed control units, and vehicle software. We understand that the difference between the adapter, the license, and the available diagnostic depth must be clear before purchase. Your feedback helps us improve how we communicate the license model, pricing, and feature availability.

Reply from Carly Solutions GmbH
Nous sommes désolés que la modification du codage des phares autoroute sur votre Golf 7 n’ait pas pu être annulée comme prévu. Nous comprenons que cela soit particulièrement frustrant lorsqu’une fonction de codage ne peut pas être restaurée facilement.
Les fonctions Carly disponibles, y compris le codage et la réinitialisation de certains paramètres, dépendent toujours de la marque, du modèle, de l’année, des calculateurs installés et du logiciel du véhicule. Il peut donc arriver que certaines modifications ou retours en arrière ne soient pas disponibles selon la configuration technique du véhicule.
Votre retour est important, car il nous aide à améliorer la présentation des fonctions de codage disponibles, de leurs limites et des informations de compatibilité avant utilisation.
Carly is a terrible app for technicians…
Carly is a terrible app for technicians and probably just about anyone else. Not only is the actual implementation of a scanner fall well short of what’s acceptable, but it costs a significant amount annually and to boot they put ads in the app that you can’t get rid of. My recommendation is to avoid Carly. Expensive and it doesn’t do half of what it promises to do.

We’re sorry that Carly did not meet your expectations, especially from a technician’s perspective where diagnostic depth, reliability, and a clear app experience are particularly important.
Carly is offered as an annual app license that unlocks the digital functions in the Carly App. The available Carly functions can vary depending on the vehicle brand, model, year, installed control units, and vehicle software, so some diagnostics or advanced functions may not be available for every vehicle configuration.
We understand that pricing, feature availability, and the in-app experience need to feel transparent and useful for customers. Your feedback about diagnostic performance and ads in the app is important to us and helps us improve both the product experience and how we communicate Carly’s capabilities before purchase.

Horrible customer service
My warranty replacement was shipped with incorrect customs documentation. Under US customs rules, free warranty replacements are not subject to customs duties. However, because Carly failed to indicate that this was a free replacement on the customs form, I was forced to pay over $30 in customs and carrier fees.
To make matters worse, the customer service refused to acknowledge the mistake or correct the form. This is horrible service, and I will be advising everyone to stay away from Carly.

We’re sorry that your warranty replacement led to unexpected customs and carrier fees, and that you felt the issue was not properly acknowledged by our support team.

Not able to clear the fault codes
Not able to clear the fault codes, old codes keep appering.
I contacted the support department. They cannot resolve it and are having it investigated further. When I inquired after a week, the complaint had been closed without offering me a solution or informing me. If I have it scanned with ISTA+, are the errors not present?
July 17, 2026
Reply from Carly Solutions GmbH
We’re sorry that the fault codes keep appearing after you try to clear them. We understand how frustrating it is when diagnostics do not behave as expected, especially when you want a clear result from the Carly app.
Fault code clearing can depend on the vehicle brand, model, year, installed control units, software, and whether the vehicle is still detecting the underlying issue. In some cases, a code may return because the control unit reports the fault again, even after it was cleared.
Please contact our support team with the vehicle details and the affected fault codes so we can review what happened technically in your case. Please do not share any personal data publicly here. Your feedback helps us identify where diagnostic behavior and guidance need to be made clearer.

Used carlyctn sort my air flow meter which I found had a 6x4 bit of plastic stuck in it which had gotten past the air filter. Must have been there a while as it's not possible to do that except when a mechanic lets it happen. Changed garage as a result.

Completely incompatible with new cars with sfd2. Ask for a refund and to cancel as its useless to me but just got a 3 month extension which is also useless to me. If you have a VAG car from 2024 onwards don't waste your money.
March 29, 2026
Reply from Carly Solutions GmbH
We’re sorry that Carly was not useful for your newer VW/Audi/SEAT/Skoda Group vehicle and that the offered extension did not address your concern.
For newer vehicles with security systems such as SFD2, access to certain diagnostics or Carly features can be technically limited depending on the model year, control units, and software configuration. We understand that this is especially frustrating if you expected the product to work for your car and then asked for cancellation or a refund.
As we cannot review license, refund, or case details publicly, please contact our support team again so your specific case, including the extension that was offered, can be reviewed individually. Please do not share personal data publicly.
