For European passenger cars, 2001 petrol and 2004 diesel are useful reference years. Hybrid coverage is limited to the combustion engine; fully electric vehicles are outside the standard use case.
Petrol and diesel reference years
The database uses 2001 for petrol and 2004 for diesel passenger cars as practical reference points. A generation that spans these dates can still vary by engine, so older versions need individual confirmation.
Hybrid means combustion-engine scope
On a compatible hybrid, OBDPhone® may read generic codes for the combustion engine and emissions. Traction-battery health, inverter data and make-specific hybrid functions are not guaranteed.
Fully electric vehicles are different
An electric vehicle has no combustion-engine emissions diagnosis. It may have a diagnostic port, but its useful data is manufacturer-specific and outside standard OBDPhone® use.
Read the confidence level
A field-observation result is stronger than a documented estimate. Probable or not guaranteed means the exact version should be confirmed before relying on it.
- Compatible: generic engine use expected.
- Conditional: check the stated year or fuel limit.
- Probable: exact test recommended.
- Not guaranteed: individual confirmation needed.
Frequently asked questions
The essential answers.
Are all petrol cars after 2001 compatible?+
It is a strong reference, not an absolute guarantee for every engine and market.
Does OBDPhone® work on hybrids?+
It may cover the combustion engine, not the complete hybrid system.
Does it work on electric cars?+
Not for the standard combustion-engine diagnostics intended by OBDPhone®.
