VDiag VD30 Pro | Owner’s REVIEW
Last Updated on April 11, 2026 by Juraj
Vdiagtool VD30 is one of the best code readers I have tried. So far only code reader I have tried that can display 4 live data graphs at once, battery test, and read different types of codes separately.

I also made a video review of this code reader, check it out in action 🙂
The only thing I disliked about the scanner was it was missing some letters in the OBD codes library. For example, if I looked up the code for fuel injector, it doesn’t say “fuel injector fault”, but ” jector fault.”
But if you scan codes from your car, the code description is complete, the bug is happening only in the library function.
Testing VD30 code reader
Ok, so this code reader can do all of that basic OBD stuff you already know like read codes/data or clear your check engine light.
But what makes it so good that I placed it in my best code reader list, even though I tested a whole bunch of them?
There are a few things making VD30 stand out:
4v1 live data
Most code readers will display live data. But not all of them will show you all possible parameters (VD30 can) and not all of them will display them as graphs.
And none of the code readers I tested so far could display up to 4 different values at once!
The closest was Ancel AD530 with a 3v1 live data stream, but VD30 is the first to display 4v1 (from what I tested)
To be honest, reading 4 engine live data parameters looks pretty confusing on the small screen but that is the problem of code readers in general.
They just don’t come with a screen big enough to display multiple separate graphs.
VD30 is a great overall code reader
VD30 just does it all.
From separating codes which not all code readers can do (show permanent, current, and pending codes in separate tabs) up to multiple live data graphs make it one of best code readers I have tried so far 🙂
