Carly – Complete Diagnostics and Coding Tool for Your Car

What is Carly and what is it used for?

Carly is a mobile app and OBD2 adapter that allows you to diagnose, code, and monitor your car directly from your phone. The app has become a popular choice for car owners who want to save money on workshop visits and gain full insight into their car's health and functions.

Originally developed for BMW, Carly has now expanded to support more brands, including:

• Mercedes-Benz

• Volkswagen

• Audi

• Toyota

• Mini

• Skoda

• Seat

The app doesn't just focus on troubleshooting – it also offers coding capabilities, service functions, and advanced live data.

Best of all? You don't need any technical training. With the right adapter and a few clicks in the app, you have access to information that previously required professional equipment.

For recommended adapters and support in Swedish, see Felkodslasare.se.

How Carly works in practice

Carly consists of two parts:

1. The mobile app – available for iOS and Android

2. OBD2 adapter – connects to the car's diagnostic port

User flow:

• Connect the adapter to the car's OBD2 port (under the steering wheel)

• Connect your phone to the adapter via Bluetooth

• Open the app and select your car model

• Perform diagnostics, coding, or live data monitoring

The interface is intuitive, color-coded, and easy to understand – even for beginners. The app provides clear fault codes, explanations, and suggestions on what needs to be fixed.

Supported car brands and models

Carly is one of the few apps that works with multiple car brands – however, functionality varies depending on the model and year.

Fully supported brands (with coding & diagnosis):

• BMW (incl. MINI and some Toyota Supra)

• Mercedes-Benz

• VAG group (VW, Audi, Skoda, Seat)

Partial support for:

• Porsche

• Renault

• Toyota

• Ford

• Opel

• Volvo (limited)

You can see the exact functionality for your specific car via Carly's website or directly at Felkodslasare.se, which also provides guidance on compatibility.

Carly for BMW – special features

Carly is particularly powerful for BMW owners. The app offers functions that are otherwise only available at authorized workshops or with advanced tools.

Exclusive BMW features with Carly:

It is this breadth of functionality that makes Carly one of the most comprehensive options for BMW.

Diagnostics with Carly – what can you read out?

Carly's strength lies in its ability to read out fault codes from all modules in the car – not just engine control.

Supported modules:

• DME/DDE – Engine control (petrol/diesel)

• EGS – Gearbox

• DSC/ABS – Brake system

• SRS – Airbag system

• KOMBI – Instrument panel

• FRM – Lighting module

• CAS/BDC – Comfort & anti-theft

The app displays:

• Fault code

• Clear description

• Severity level

• Possible solution (via "Smart Mechanic")

You can also erase fault codes directly – but only after the problem has been fixed to avoid the code recurring.

What is "Smart Mechanic" in Carly?

Smart Mechanic is Carly's AI-based analysis function. It combines fault codes with data from the car's ECU and provides suggestions for possible causes and actions.

Example:

Fault code: 2C9E – Lambda sensor: Function faulty
Smart Mechanic: Check cable, replace sensor, watch video guide

This makes Carly a tool even for troubleshooting at home in the garage.

Live data and real-time monitoring

Carly also offers live data – a function that displays information from sensors in real-time while the car is driving or idling.

Examples of live data:

• Engine temperature

• Boost pressure

• Intake pressure

• O2 sensor data

• Ignition timing

• Fuel pressure

You can use this data to:

• Identify operational disturbances

• Check component functions

• See how the car performs while driving

You can also export logs to Excel or PDF.

Coding functions – what can be changed with Carly?

Carly makes it possible to change various settings in the car's control system – just like Bimmercode, but with support for more car brands.

Examples of codings:

The app only displays the codings that are compatible with your specific car – which minimizes the risk of errors.
