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.

We’re sorry that the coding features did not work as expected for your vehicle. We understand how frustrating it is when you buy Carly for a specific feature and then cannot use it as planned.
Available Carly Features depend on the vehicle brand, model, year, installed control units, software version, and technical configuration. This means that a vehicle may be generally supported while individual coding features are not technically available for every variant.
Since we cannot check your vehicle details publicly, please contact our support team so they can review the specific coding feature and your vehicle configuration. Please do not share personal data here on Trustpilot.
Your feedback helps us make our compatibility and feature information clearer before purchase.

We’re sorry that Carly has not worked reliably for you. We understand how frustrating it is when the app or expected features do not behave as they should.
Available Carly Features can depend on the vehicle brand, model, year, installed control units, software version, and technical configuration. Because of this, some features may work differently depending on the specific vehicle setup.
Your feedback is important to us, as it helps us improve both product reliability and the way we explain feature availability and compatibility before purchase.

We’re sorry that Carly has not been able to read the computer on your 2006 Jeep Wrangler TJ, especially since the vehicle was listed as supported. Compatibility can depend on the vehicle’s installed control units, software, and technical configuration, but if support for this model was shown before purchase, we’d like to review it.

I paid for the top package with every car included, it doesn’t show codes that actually could detect a fault with your car engine, turbo etc. my car only showed a NOX sensor on Carly OBD but taking it to Volkswagen revealed the turbo was totalled. And the customisation doesn’t work either.
On top of that they do their best to hide a yearly subscription when you purchase it, no direct debit shows on an account with no warning they are going to charge another £104 annually and do not offer any sort of refund. I have used it maybe twice in the year I have had it and don’t plan to use it again go for a cheaper OBD reader that actually shows necessary codes. DO NOT BUY

Unprompted review
Reply from Carly Solutions GmbH
We’re sorry that Carly did not meet your expectations for diagnostics, customisation, and the annual app license. Carly can read fault codes reported by the vehicle’s control units, but available data and functions depend on the vehicle model, installed control units, and software. Carly is offered as an annual app license that renews unless automatic renewal is disabled beforehand, and activated digital licenses can only be refunded in limited cases. Your feedback helps us improve how we communicate diagnostic scope, feature availability, and renewal terms before purchase.
An excellent product
An excellent product, bought owing to problems with my daughter's BMW E92 which it resolved, but also offers a great many other features that I was not expecting, such s coding to open/close features of the car that I would have thought only available to a BMW Authorised Dealer

Although a potentially good product
Although a potentially good product, the whole subscription service is very sales orientated and your OBD becomes a brick without it. Seems everything now is subscription based and you never actually own products anymore

I blew an engine on 2015 Toyota Avalon, Carly gave no warning. Also the tranny went on the family's 2020 Toyota Corolla again without a warning from Carly.

We’re very sorry to hear what happened with your vehicles. We understand how upsetting it is when serious issues occur without any warning. There can be many reasons why this happens, and not every mechanical problem will show clear electronic signs that a diagnostic app can detect in advance. Still, we understand your point and regret that Carly did not give you the reassurance you expected. We’re sorry to see you go.

Hi, we’re sorry that you feel you have already paid and are still being asked for more money. We understand how frustrating and confusing that can be.
Carly’s pricing can include different parts, such as the Carly Scanner and the annual Carly app license, depending on what was purchased. Since we cannot review payment, license, or account details publicly on Trustpilot, please open a new ticket here: https://support.mycarly.com/hc/requests/new?ticket_form_id=360000444960
Please write “To Support Manager” in the ticket title or subject so your request can be correctly assigned. Please do not share any personal payment details publicly. We’ll be happy to review what was charged and clarify the status of your license.
Reply from Carly Solutions GmbH
We’re sorry that Carly felt like a paywall to you. We understand how frustrating it can be when expected features require an active Carly app license.
Carly offers both free basic access and paid license options, depending on the features you want to use. More advanced Carly Features are part of the annual Carly app license, and we aim to make this clear before purchase.
Your feedback is important because pricing and feature access should be easy to understand. We’ll continue working on making this clearer and more transparent for customers.

I never signed up for renewals this site is kinda hacky.
July 19, 2026
Reply from Carly Solutions GmbH
We’re sorry that the renewal came as a surprise and that the process felt unclear to you. Carly is offered as an annual Carly app license, which renews automatically unless the automatic renewal is cancelled before the end of the current license period.
The renewal information is shown during the purchase process, but we understand that this may not have been clear enough in your case. After a renewed license period has started, refunds are limited because Carly is a digital license product.
Since we cannot review account, payment, or license details publicly, please open a new ticket here: https://support.mycarly.com/hc/requests/new?ticket_form_id=360000444960

The scanning is slow
The scanning is slow, takes too much time. Meanwhile the car shows signs that there is a huge error, creates panic, that an unexpected error will brick my car, and a complicated service will be needed.
The endresult was not meaningful or useful for me, even on the scale how urgent is my issue, or what kind of service is needed.
Too many errors on the list, but i was afraid to clear them, hope oart of those are old.
April 22, 2026
Reply from Carly Solutions GmbH
We’re sorry that the scan felt slow and that the number of errors shown created concern instead of clarity. Carly also displays historical errors, not only active ones, so some entries may relate to older events. To help with this, we highlight the importance of issues using color indicators such as green, yellow, and red. If an issue was not marked as critical, it means Carly did not identify it as a critical error. We understand that this experience felt stressful and regret that the result was not as helpful as expected.

It was advertised I will be able to customize coding if I buy the highest package but unfortunately it is not available for my Lexus. Only German vehicles 😐
July 19, 2025
Reply from Carly Solutions GmbH
We’re sorry that the coding options you expected were not available. Available functions depend on the exact vehicle details, installed control units, software, and manufacturer permissions, so coding can vary significantly by brand and model. We do also have a dedicated Lexus page where supported functions can be checked before purchase. We regret that Carly did not meet your expectations in this case.
Reply from Carly Solutions GmbH
We’re sorry that the annual payment model was not clear enough before purchase. Carly is offered as an annual app license, which means the license is paid for the full year rather than as a monthly subscription.
We understand that this can be frustrating if you expected a monthly option. Our goal is to make the license duration and pricing as transparent as possible during the purchase process, and your feedback helps us improve how this information is shown before checkout.

Connects , underwhelmed with programming option for Volvo
Connects ok, but after buying the programming option for my Volvo xc60 I was a bit underwhelmed with what was unlocked for the extra cost. It has loads of options for other manufacturers though, for example BMW. An update for the Volvo system would be appreciated, didn't want to get vdash or Vida but might have to for a simple thing like changing the Speedo from mph to km/h

Thank you for your honest feedback. We’re glad the connection works well for you. We understand that the programming options for your Volvo XC60 felt limited compared with what may be available for some other manufacturers, such as BMW. The available functions can vary depending on brand, model, year, software, and installed control units. We appreciate your suggestion for a Volvo update and will take it as valuable feedback.
