Fault Codes
Our fault-code library explains what a code means and connects it to symptoms, likely causes and the next diagnostic steps.
About OBD Europe
OBD Europe is a vehicle diagnostics specialist operated by Dalset Oy in Ylöjärvi, Finland. Our focus is vehicle diagnostics: connecting fault codes, real-world symptoms, diagnostic procedures and professional diagnostic tools into one practical knowledge base.
Our purpose
OBD Europe is built around one core principle: a fault code or symptom should start a diagnostic process, not automatically trigger a parts replacement. Our goal is to help vehicle owners, technicians and workshops understand what a fault means, what evidence to check next and which diagnostic tools are appropriate for the job.
Our fault-code library explains what a code means and connects it to symptoms, likely causes and the next diagnostic steps.
Symptom-led guides help connect what the driver or technician observes to the systems and tests that can explain it.
Procedure guides explain how diagnostic information such as live data, fuel trims, freeze-frame data and active tests should be interpreted.
How we build the knowledge base
Our editorial work is based on manufacturer documentation, industry standards, established diagnostic procedures, professional diagnostic knowledge and practical troubleshooting. Real-world experience is used when it adds useful context to the diagnostic process.
We prioritise technically sound information over publishing quickly. Diagnostic claims should be supported by a clear technical basis.
A useful diagnostics page should explain what the information means in practice and what should be checked next.
Fault codes, symptoms, diagnostic procedures and tools are linked so that each page can continue the diagnostic journey.
We do not treat a fault code as proof that a named component must be replaced. Diagnosis comes before parts replacement.
We do not intentionally publish unverified repair advice or copy manufacturer documentation as a substitute for explanation.
OBD Europe has a deliberately narrow focus: vehicle diagnostics, diagnostic procedures and the tools used to perform them.
Knowledge + commerce
OBD Europe is both a diagnostics knowledge resource and an online store for diagnostic tools. Dalset Oy sells products through OBD Europe, and some guides link directly to products we offer.
Commercial activity supports the continued development of the knowledge base. The tools we present are selected around diagnostic capability, intended use and long-term usability.
The purpose of the content is to help users diagnose more accurately. When a tool is relevant, the content should explain why that level of diagnostic capability is useful rather than simply directing the reader to a product.
