What is an OBD2 port?

Nowadays, cars are increasingly dependent on their software and have up to 80 built-in ECUs. Therefore, to find problems and errors in modern cars it is necessary to own a diagnostics tool.

Since 2004, all vehicles, and some from 1994 and later, are equipped with an OBD2 port. This OBD2 port allows you to connect an OBD2 scanner to your car in order to access hidden features and information!

However, the location of this port depends on the car model. Therefore, finding this port can be a bit difficult sometimes! The location of the OBD2 port in a BMW 3 G20/G21 should be within the reach of the driver.

The Carly App and OBD2 adapter allow BMW owners to diagnose their car in a few steps. And without a trip to the workshop! Additionally, Carly supports multiple other functions for the BMW 3.

However, the Carly functions available for specific cars can vary due to differences in the built-in ECUs and the car’s software. Here you can check all the functions that are available for coding, diagnosing, and saving money on your BMW 3 G20/G21!

The Carly OBD2 Reader and Carly App for your BMW 3 G20/G21

To access your BMW 3 G20/G21 functions, there are two simple steps to follow:

Firstly, you need to get the Carly OBD2 scanner and plug it into the OBD2 port in your BMW 3.

Lastly, all that is left is to download the Carly App and get a subscription for your car model to access all the premium Carly features. If you also have another car from a different brand, we recommend you get the “all brands subscription”.

This way you’ll be able to access the functions for all car brands! You can get the Carly OBD2 Scanner (called the Carly Universal Adapter) and Carly app subscription directly from the website.

Now that you have your OBD2 reader and Carly App you can start making your BMW 3 G20/G21 yours!

Like having your own mechanic!
