Key takeaway

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.

01

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.

02

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.

03

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.

04

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.

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®.
