Carly has established itself as a pioneer in simplifying complex car diagnostic systems, bringing professional-level insights to everyday car owners. The Carly OBD2 Scanner is a compact, user-friendly device designed to tap into the vast data network within your vehicle. By connecting to your smartphone via the Carly app, this tool translates raw vehicle data into actionable information, highlighting potential faults and offering a window into your car’s health.
Equipped with a powerful 32-bit ARM processor, the Carly scanner is engineered for broad compatibility, capable of reading electronic control units (ECUs) across a wide range of vehicles, from a Volkswagen Polo to luxury models like a Bentley Mulsanne. Its versatility is further enhanced by its adherence to the OBD II standard, mandatory for petrol cars sold in the EU since 2001 (and 2004 for diesel). This compliance ensures that the Carly scanner is compatible with a vast majority of modern vehicles equipped with the standard OBD II port, typically located beneath the steering wheel. The core purpose of such diagnostic tools is to proactively identify issues, potentially saving car owners significant expenses on repairs by catching problems early.
The Carly scanner distinguishes itself from competitors by integrating features like Mileage Check, aimed at detecting odometer fraud, within a remarkably small and affordable package. This combination of features makes it an attractive option for both seasoned car enthusiasts and everyday drivers. Paired with a premium subscription to the Carly app, users gain access to an in-depth diagnostic experience, capable of probing every electronic corner of their vehicle.
This review of the Carly Scanner is brought to you by Aaron Hussain, a classic car owner and advocate for preventative vehicle maintenance. He emphasizes the critical role of regular issue monitoring in preserving vehicle longevity, regardless of the car’s age, size, or type.
Verdict: The Carly Scanner is a pocket-sized powerhouse for preventative car maintenance, though minor app quirks prevent it from achieving perfection.
Score: 4/5
Carly Scanner: Key Advantages
Simplicity is paramount with the Carly Scanner. The process is straightforward: locate the OBD II port in your car—typically found under the steering wheel—and plug in the device. Once connected, the Carly scanner begins its work, transmitting data to the Carly app on your smartphone. The app then presents the diagnostic readings in an easily understandable format, eliminating the need for complex manuals or technical expertise. While scan times can vary depending on the number of electronic modules in a vehicle, users should expect an average wait of 5 to 10 minutes for a comprehensive scan. After scanning, you can easily navigate the app to identify areas needing attention and clear fault codes as needed.
A standout feature of the Carly Scanner is its Mileage Check. This innovative function is designed to identify potential mileage discrepancies by cross-referencing data from various vehicle control units. It effectively detects instances where the odometer may have been tampered with, providing a crucial layer of security, especially when evaluating used vehicles. During our tests, the vehicles examined showed consistent and legitimate mileage readings, confirming the function’s accuracy. This feature is an invaluable asset for anyone in the used car market, offering peace of mind against odometer fraud.
However, the true strength of the Carly Scanner lies in its broad vehicle compatibility. Since 2004, OBD II ports have been standard in virtually all cars, making the Carly Scanner universally compatible with a vast range of makes and models. From everyday vehicles to high-performance sports cars like an Aston Martin Vulcan or a Shelby Ultimate Aero, the Carly Scanner can be utilized across the spectrum. This versatility makes it an essential tool for anyone buying a car manufactured in the 21st century, offering a quick and reliable way to assess vehicle health during a test drive.
Carly Scanner: Acceptable Aspects
It’s important to recognize that diagnostic scans may reveal historical data that hasn’t been cleared from previous diagnostics. If a vehicle has been scanned before, the Carly scanner will likely display these pre-existing codes. The responsibility falls to the user to interpret these codes and clear them appropriately after addressing any genuine issues.
While the Carly scanner provides a wealth of diagnostic information, users need to discern between critical issues and less significant, historical codes. The scanner’s thoroughness in reporting all detected issues is a positive aspect, ensuring no potential problem is overlooked.
The value proposition of the Carly Scanner is also nuanced. The base product, priced just over £56, offers fundamental diagnostic capabilities. The Carly Used Car Check feature is accessible to all users with a free account and app download, adding immediate value.
The premium subscription model introduces pricing variations depending on vehicle brand, reflecting feature availability and complexity. For example, Mercedes vehicles may require a higher subscription tier compared to Ford to unlock brand-specific functionalities. Holden vehicles might only support the basic package. Prospective users should investigate the subscription options relevant to their specific vehicle make to understand the features and costs associated with their car.
Carly Scanner: Drawbacks
Given the complexity of modern vehicles with numerous electronic modules, the Carly Scanner requires a considerable amount of time to comprehensively analyze each system. While this thoroughness is technically necessary, the wait time, potentially up to ten minutes per scan, can be perceived as lengthy. Scanning time is also vehicle-dependent; a technologically advanced Mercedes S-Class will naturally require longer scan times compared to a simpler car like a Toyota GT86.
While seasoned mechanics might find the Carly Scanner’s diagnostics somewhat simplified and its response times slower than professional-grade tools, for the average car buyer or owner, it provides an invaluable service. It bridges the gap between basic code readers and expensive professional diagnostic equipment, empowering users to make informed decisions about vehicle maintenance and used car purchases.
Moving beyond the scanner itself, the Carly app experience has some minor drawbacks. A persistent feedback pop-up, requiring a minimum character count, interrupts the user flow, particularly during the Used Car Check. This mandatory feedback step, while intended for user input, can be an unwelcome interruption.
An anomaly was also noted in the car selection menu: the Audi RS2 was incorrectly listed with a production year range of 2000-2005, when its actual production years were earlier. While seemingly a minor detail, such inaccuracies can undermine user confidence in the app’s data precision.
New Feature: Carly Community (November 2024)
Carly has recently enhanced its platform with the Carly Community, launched in November 2024. This online forum is designed to connect motorists, enabling them to share diagnostic queries and receive advice from certified mechanics and other vehicle owners within the Carly ecosystem.
Users can specify their vehicle make and model, categorize their issue, and describe symptoms in detail before posting questions to the community. The platform also allows users to browse existing queries from other owners. Initial observations suggest that the responses from Carly Mechanics within the community are detailed and offer valuable insights into potential vehicle issues. While the Carly Community can be a helpful resource for gaining preliminary understanding and narrowing down potential problems, it’s crucial to remember that online advice should complement, not replace, a hands-on inspection by a trusted mechanic for accurate diagnosis and repair.
New Feature: Repair Cost Calculator (August 2024)
Another recent addition to the Carly suite is the Repair Cost Calculator, introduced in August 2024. This tool aims to provide users with estimated repair costs for various vehicle issues.
Users can leverage data obtained from their Carly scanner for more precise estimations, or manually input vehicle details (make, model, and symptoms) using drop-down menus. The calculator then generates a results page listing potential issues and associated repair costs, categorized by severity based on estimated expense.
In a test case using a 2014 BMW 5-Series with squeaky brakes, the calculator provided surprisingly relevant results. It presented four possible causes, ranging in cost from £200 to £2,000, and even included estimated labor times. Currently, the Repair Cost Calculator is not integrated into the Carly app, which would enhance its usability. Despite this limitation, it serves as a valuable companion tool to the scanner, although the accuracy of its cost estimations requires further evaluation.
