Выявленные причины
Engine Knock (Detonation/Pre-ignition)
75%This occurs when the fuel-air mixture ignites prematurely or unevenly within the cylinder, creating a sharp pinging sound. It's often caused by incorrect ignition timing, low octane fuel, or excessive carbon buildup.
Exhaust Leak
60%A small leak in the exhaust manifold or pipes can sometimes produce a ticking or pinging sound, especially under load when exhaust pressure is higher.
