Clear fault codes with the renault Diagnostic App

Car Diagnostics

Understand your car's health

Using your smartphone, Carly enables you to easily catch potential problems before they cost you dearly. Engine related costs may rise up to $10,000 in case of a total damage. Mechanics recommend running diagnostic sessions several times a year, but each session can easily cost you over $60.

Carly can read out fault codes from all important built-in electronic control units, going deeper than OBD-level. You will receive the exact same code any professional garage would, together with an interpretation of the severity.

Car Coding

Car Diagnostics

Clear fault codes

After performing diagnostics, you get a fault report, but not every fault code implies a current defect. Clear the OBD- and manufacturer level codes and perform a second diagnostic. The codes that stay need your attention.
