How it works

Understand DIY car maintenance

There are built-in maintenance features in your car that you might not have access to operate. Carly guides you step-by-step through simple maintenance fixes such as service reset and battery registration.

Used Car

The possibilities depend on your individual car.

What Carly can do for you varies from car to car. Find out how it works for yours.

Service with one tap

All car maintenance functions

See below the features that Carly enables, and check your specific car by connecting to the Carly Universal Adapter and lite app.

Maintenance
OBD
OBD Functions
Arrow down
What it does

OBD Diagnostics: Reads and deletes all OBD engine and transmission fault codes. With the Health feature, manufacturer-specific error codes can be read from all systems.

OBD Live Engine Data: Monitor your driving style and perform maintenance work with detailed data (e.g. oil temperature, rpm)

Emission Check: Test procedures for exhaust systems (e.g. misfire check, fuel system etc) and be fully informed for your smog test.

Service Reset
Service Reset
Arrow down
What it does

After changing the oil or brakes yourself, reset the service point through the app. View extended service data to see how often certain service points have been done on your car.

How you benefit

Save time and money by changing your oil or brakes yourself, and simply doing it with a press on the app button.

Battery Reset
Battery Reset
Arrow down
What it does

With the Carly app, you can register the battery of your choice in the car.

How you benefit

When you go to the car shop they offer you only the original manufacturer's battery, which is more expensive (~ USD 300), and on top of that the service presents additional costs (~ USD 200). Save time and money on the service and the battery of your choice.

DPF
DPF
Arrow down
What it does

With the Carly solution app you can check the DPF (Diesel Particulate Filter) critical values - i.e. soot mass, ash mass, average engine speed. If needed, you can request a DPF regeneration and track the process.

How you benefit

Above a certain amount of ashes, it affects the fuel consumption and power. In a critical case the filter cannot regenerate itself and a filter change can cost you up to USD 3,000.

NOX
NOX
Arrow down
What it does

Often your BMW petrol engine cannot regenerate itself and you need to replace the filter. That happens when the capacity to store the nitrogen oxides is reached. With Carly you can check the loading status of the catalyst by certain parameters and start the regeneration manually, live-monitor your NOX and track the regeneration.

How you benefit

If you act before the warning lights on the dashboard appear, you can save anywhere from USD 2,000 to USD 3,000 for the NOX filter replacement, which the dealer will be happy to install in your car. Above a certain amount it affects the fuel consumption and the power.

Brake
Brake
Arrow down
What it does

To be able to perform work on the brake system, it is necessary to set the servo motors of the brake system in the workshop mode first. With Carly it is easy to set your electronic parking brake into the Service mode and also back into Operation mode. In addition to an electronic parking brake, many modern vehicles also have a brake wear sensor, which informs you about the wear point of the brake pads.

How you benefit

Carry out repair work on your brake system by yourself. Calibrate your parking brake as if it was brand new.

Transmission
Transmission
Arrow down
What it does

Your automatic transmission continuously learns about your current driving behavior. With this feature, you have the opportunity to observe the most important parameters and reset learning values directly at the push of a button. Only request it if needed.

How you benefit

Now you can read and reset automatic transmission values to fit your style more quickly. This is valuable especially in cases when you are buying a used car - for example, the previous driver was doing short city trips, while you spend most of the time on highways.

Can I break my car, or could my warranty expire after using Carly?

The Carly solution is safe to use and should not break your car or affect the warranty if you use it correctly and in line with our recommendations — just like with every other car tool.

Carly makes a backup every time you code, and you can quickly return to the original settings if you want. Also, Carly is the only coding solution worldwide that has a proactive ECU check installed. We check before encoding whether your controller has a "clean" firmware.

What you need to be careful about is not to change too many options at the same time. And in rare cases, there are controllers with firmware that could potentially cause problems after a coding process. But no worries, we will inform you about it in the app.
