Our Team

We’re a small, dedicated team of car enthusiasts, diagnostic specialists, and e‑commerce professionals based in the Czech Republic. OBD4 began with a simple frustration: it was hard to find honest sellers of reliable automotive diagnostic tools. So we built the store we wished existed — fast, helpful, and grounded in real workshop experience.

We do not outsource support. When you contact OBD4, you speak directly with someone who understands the tools, the systems, and real‑world use cases — from reading fault codes and service resets to ECU programming and module coding.

Who We Are

We serve DIY mechanics, independent workshops, and tuning enthusiasts who want reliable tools without dealer‑level prices. At OBD4, we partner with expert suppliers to offer a curated range of tested and verified hardware — from universal OBD2 scanners to brand‑specific interfaces and advanced ECU (Engine Control Unit) programming tools.

You’ll find trusted and compatible solutions including different iCarSoft, ThinkDiag, Launch, ELM327, Multidiag Pro, and alternatives of popular diagnostic tools like VAGCOM, Autocom CDP, Delphi DS150e, DICE, Openport — each selected for performance, compatibility, and long‑term support.
