What does OBD stand for?
Let’s start with the main term that will help you understand it all! The initials “OBD” stand for “on-board diagnostics”. The OBD systems give car owners and/or mechanics access to the status of the many sub-systems a modern vehicle has.
Moreover, an OBD reader (also called adaptor or scanner) is a pocket-sized electronic device. It that allows you access to this data, helping you see a car’s overall health status.
Additionally, an OBD reader also helps you detect faults earlier than your car would. It also makes it possible for you to carry out your own maintenance for your car. Thus, these features can help you save money by detecting errors early and avoiding unexpected expenses at the mechanic’s workshop!
The best part about all of this, its that you can access the data and carry out these diagnostics all by yourself in no time! Basically, you just plug the Carly OBD reader into your car, open the Carly app on your phone, and start just with a couple of taps from your phone!
For some car models, an OBD reader (technically, an OBD2 reader, as that is the latest standard) even allows you to code cool features to personalize your car.
In order to access this information and features, you only need to purchase the Carly OBD Adapter and download the Carly app.
The Carly app is the software that lets you access all the information that the OBD reader collects from your car. With the app, you can easily view your car’s information and makes changes to the software (aka coding) via your phone.
Now that you know what an OBD reader is, let’s get into detail and find out how it works!
What is the difference between OBD1 and OBD2?
With the previous generation of OBD adapters, the only way for connecting them to your phone was through a long cable. However, with the introduction of OBD2, you have access to more standardized error codes. Additionally, you can also connect the adapter to your phone via Bluetooth or WLAN, without the need for cables.
At Carly, you can find the “Carly Universal Adapter” which is an OBD2 reader and can be used for almost all car brands in the world!
What is an OBD port?
Now that you know what an OBD reader is, we can move to the OBD port! An OBD port is simply a space that is uniquely designed for connecting the OBD reader to it.
When you take your car to the mechanics, this is the outlet where they plug in the OBD equipment. Nevertheless, their equipment usually consists of a long cable and a computer that lets them access your car’s information. Once they connect their equipment to the OBD port, they can diagnose your car and find out what parts need to be repaired, for instance.
However, with the Carly OBD and app, you no longer need to visit a mechanic or use all this complicated equipment to access your car’s data. Now, you can easily diagnose your car through your phone and a lightweight OBD adapter that you can carry in your glovebox everywhere!
Do all cars have an OBD port?
Nowadays, cars have up to 80 built-in ECUs in their system. An ECU stands for “electronic control unit”. These units are embedded in the car and they control one or more electrical systems of a vehicle.
For example, there is a specific ECU in your car that controls the fuel system. With an OBD reader, you are able to access this ECU to get data about your fuel system!
The embedded software in these ECU makes cars more sophisticated, not just in their functions but also in how much data they provide!
You can find an OBD2 port in all gas vehicles manufactured since 2001 in the European Union, and in all vehicles from 1996 onwards in the USA. Therefore, if you own a car manufactured in recent years, it will be equipped with an OBD2 port!
Is the Carly OBD compatible will my OBD port?
If your car was built after 2001, the answer is probably yes! However, if you own a BMW manufactured prior to 2001, we got you covered too! The Carly Universal Adapter is compatible with:
- Vehicles manufactured from 2001 onwards
- Mercedes built from 2005 onwards
- And every BMW from 1996* and later!
If you are not sure about your car’s manufacturing date, you can find this information in your vehicle’s registration documents. You can also check if your car brand and model are supported by the Carly OBD2 reader!
In case that you have a BMW car manufactured between 1996 and 2000, you will also need a 20-pin adapter extension to use the Carly Universal Adapter! However, don’t worry about this additional extension. You can easily find it for affordable prices on eBay or Amazon, for instance.
When looking into purchasing Carly, you might find the Carly adapter for resale on eCommerce sites. However, we highly advise you only buy adapters via our website and avoid buying Carly on eBay or other sites. This is because the Carly adapters sold by external sites or people, are resold for higher prices and do not include a product warranty or access to our return policy.
Carly Tip: If your requested model is not listed, choose another model of your car brand with the same build year.

Where is the OBD2 port?
The OBD2 port location can vary depending on your car model. However, it is usually found within reach of the driver, underneath the steering wheel. Scroll down to see where the OBD2 port is located in your car! Additionally, you can also check the location of the OBD2 port in your car’s manual.
What can an OBD2 tell you?
There are 4 main data categories that the Carly OBD scanner can give you access to. Each category has many functions available for your car. However, before we dive in and explain these powerful features, it is important to note that the available functions depend on the model of your car. For example, for BMW all the functions are available, but for Mercedes, only some might be available.
So let’s start with the first category!
Once you connect the Carly adapter to your car’s OBD2 port, you will be able to diagnose your own car from your phone! Basically, the Carly app will tell you if there are any problems or “fault codes” with an ECU, and how severe these faults are. Based on the number and severity of these fault codes (also called “error coded”), the Carly app will give your car an overall health score.
Usually, when your car needs repair or an oil change, a warning sign appears on your dashboard and you have to address these error codes immediately. However, with the Carly OBD scanner, you will be able to see errors months before they appear on your car’s dashboard. Therefore, you will aware of what part of your car need repair before it’s too late and it becomes a severe and expensive problem.
In the case that your car has error codes, the Carly app will tell you what they are related to and what they mean. However, with the maintenance feature, you can even save more money and do simple car repairs yourself!
Depending on your car model, the Carly app will give you possible options and a step-by-step guide of which maintenance fixes you can carry out on your car. For example, these can be undertaking a service reset (changing oil or brakes), registering the battery, and more!
The benefit of doing repairs yourself is that you can save a lot of time and money on basic car services. Once you have corrected all the error codes that the Carly OBD2 scanner detected, you can delete them in just one tap!
Moreover, the third category of possibilities is coding your car! This Carly feature lets you code particular ECUs and make your car unique. For example, you can customize the external lights, disable the automatic start-stop button, show the speedometer digitally, and much more! Again, the coding options available depend on your car model. Here you can see all the coding possibilities for your vehicle!
Last but not least, is the “Used car check” feature. If you’re buying a used car, it is easy to get tricked since sellers may alter the car’s mileage or hide important information from you. However, this is easy enough to avoid with the right tool, such as Carly!
When connecting the Carly adapter to an OBD2 port, you will be able to see valuable information about the car. For example, the Carly app will tell you whether the car’s mileage has been manipulated and by how many miles. Additionally, you can also detect serious mechanical problems, see the driving history of the vehicle, and more!
Can you drive with an OBD reader plugged in?
Now that you know what is an OBD port and how the Carly OBD reader works, the last question remains! Can you drive with the Carly adapter plugged to your OBD2 port? Absolutely! With the Carly Universal Adapter, you can plug it into your car and never worry again about unplugging it! Therefore, you can leave the Carly OBD reader plugged in your car even while you drive.
So, now that you know what an OBD port is and how to use it, answer this question for yourself:
Are you ready to have more control over your car?
