1. An apparatus for diagnosing engine wear, comprising:
a detachable puck sensor configured to be placed within an engine bay of a vehicle, the puck sensor including at least one microphone for capturing sound data and at least one accelerometer for capturing vibration data;
an onboard diagnostics (OBD-II) module configured to connect to the vehicle's OBD-II port and collect event driven or asynchronous engine performance metrics;
a wireless communication interface establishing a secure link between the detachable puck sensor and the OBD-II module or a smartphone to transmit the sound data and vibration data;
the smartphone application configured to receive, raw data comprising the sound data, vibration data, and engine performance metrics; and
a backend server system configured to receive the raw data from the smartphone application and perform AI-based diagnostics, wherein a Dynamic Time Warping (DTW) algorithm is applied to align the time-series data from multiple sources and the event driven or asynchronous engine performance metrics prior to identifying engine wear patterns.
