About Us
We’re a small team of car lovers, diagnostic experts, and e-commerce professionals based in Czech Republic. We started OBD4 because we struggled to find honest sellers of good tools ourselves. So we built what we wanted — a store that’s fast, helpful, and built on real automotive experience.
Let customers speak for us
from 94 reviewsImpeccable. J'ai pu faire mon diag, régler ma pompe.
Nickel.
Hab noch nicht alle Funktionen probiert, sieht aber aus als würde alles gehen.
Bei der Installation wird eine cloud geladen, ich konnte die Software nicht direkt davon runter laden sondern musste einen Akkount erstellen, die Software Zwischenspeichern und konnte sie erst danach auf den PC laden. Hat aber alles super und besser als bei allen anderen bis jetzt gekauften Diagnosetools funktioniert.
Great service, perfect product!😉
Very great shop! Quick answers and good service. :)
Working great and confirm the description.
Amazing people, amazing response....
Have a nice day😇
I bought the J2534 for my Volvo V70 II to use with vdash. It works perfectly. Reading, changing, coding, everything works.
Regarding the purchase process with OBD4: excellent processing, very fast shipping and with tracking I knew evertime where my package was.
I very much recommend OBD4 and would buy there again.
Great product works well
I had some problems with Windows 11
But they helped me through the support and adjusted the program for me.
Works super really very happy with it
Thank you for help to make it work
Tutto ok
Best communication. Customer service replied and solved my issue in literally 3’. Definitely recommended webshop.
First ordered the model that supports vehicles till 2017, but I could return it for a refund and then ordered the full chip model. Working great!
Great , it seems to work well
👍
Follow the instructions and it works how it should! Thank you.
