Frequently Asked Questions
Do I need an OBD2 scanner or a diagnostic app for my car?
A diagnostic app or OBD2 scanner can help UK drivers understand their car's health, diagnose warning lights, and even prepare for their MOT, potentially saving money on garage visits. While some apps require a physical scanner, others like Carvy work solely from your smartphone.
Can car diagnostic apps help me pass my MOT?
Yes, diagnostic apps can help identify potential issues that might cause an MOT failure, such as illuminated warning lights, faulty emissions, or problems with brakes and suspension, allowing you to address them before the test. Carvy, for example, offers MOT history lookup and advisory cross-referencing.
How accurate are car diagnostic apps?
The accuracy of car diagnostic apps varies. Apps like Carvy use AI to interpret data from your vehicle's systems, providing plain English explanations and potential solutions. More advanced apps can read specific fault codes and live data, offering insights often with high accuracy for engine-related issues.
