How to Diagnose Acceleration Noise in Your i20

Listening closely while driving cautiously, using a mechanic’s stethoscope, or capturing audio with a smartphone can reveal hidden issues. Visual inspection of exhaust pipes and mounting points helps pinpoint exhaust leaks, while checking engine mounts reveals potential wear contributing to vibrations.
