Live data shows real-time readings from your car’s sensors and systems. It includes parameters like RPM, coolant temperature, throttle position, battery voltage, and more.
Unlike fault codes that only tell you what went wrong, Live Data gives you context – helping you understand why the issue happened, where it's occurring, and how the system is behaving.
It’s a powerful tool for monitoring vehicle performance, identifying root causes of problems, and checking whether a fix has worked.
What kind of information can OBDeleven live data show?
Available parameters vary between car brands, models, control units, and even software versions. In general, live data is available for vehicles from:
Volkswagen Group (Volkswagen, Audi, Škoda, SEAT, Cupra)
BMW Group (BMW, MINI)
Toyota Group (Toyota, Lexus)
All other vehicles from 2008 onwards (with CAN-bus protocol)
Some common examples include:
Engine RPM
Coolant temperature
Intake air temperature
Throttle position
Battery voltage
Fuel trims
Oxygen sensor readings
Turbo boost pressure
Transmission oil temperature
Vehicle speed
Each value is read live from your car’s sensors. If something looks off, you can dig deeper or compare with expected values to pinpoint problems.
