Clear fault codes

Finally, you can clear fault codes - through your smartphone. 

After performing diagnostics, you get a fault report with fault codes. Not every fault code implies a defect. You can clear all codes and repeat the diagnostic session. The codes that remain or return should be focused on. 

Monitor live-parameters

Live parameters can help you take the guesswork out of understanding what your car needs or what the fault origins are. 

Monitor detailed engine gauges such as temperature and pressure values.

Test emission relevant systems and procedures of your car. Catch issues yourself, before you get your car serviced and talk to your mechanic on eye-level.
