My first OBD2 tester

May 1, 2025

Why is it worth having your own OBD tester?

Every driver wants to know the condition of their car. An OBD tester like SDPROG is a practical tool that allows you to quickly diagnose faults, monitor engine performance, and prevent costly breakdowns. It's a must-have tool not only for automotive enthusiasts and tuned car owners, but also for anyone who wants to care for their car consciously and economically .

1. Self-diagnosis of faults – full control over the car

With the OBD tester, you can quickly read DTC error codes , check the correct operation of sensors, the exhaust system, and the DPF/FAP system. You no longer have to pay for every diagnostic at a workshop – all you need is your phone and an OBD adapter to determine the cause of your check engine light.

2. Saving time and money

With your own OBD tester, you can assess whether a problem requires a visit to a mechanic. Often, it turns out that a minor fault doesn't require specialist intervention. This saves you 80–150 PLN per diagnostic visit and allows you to act immediately.

3. Access to engine performance data

Devices like SDPROG enable real-time reading and analysis of parameters, including charge air temperature, boost pressure, injection rates, and lambda sensor readings. This data is crucial for both chip tuning enthusiasts and anyone who wants to understand how their engine is truly performing.

4. DPF and filter burnout monitoring

Many drivers are unaware of when their car begins the DPF filter burnout process. An OBD tester allows you to monitor this and prevent the filter from clogging.
Thanks to SDPROG:

you track engine operating parameters in real time,
you check the filter regeneration history, the average distance between burns and the duration of the process,
in combination with SDPROG DASH you get a live preview that automatically switches to DPF monitoring mode when burning starts.

5. Regular diagnostics = fewer breakdowns

Regularly checking your vehicle's technical condition guarantees peace of mind. Having your own OBD reader gives you access to information that allows you to take preventative measures and avoid unexpected breakdowns on the road.
