Two problems related to engine clicking and tapping noises have been reported for the 2010 BMW M3. The most recently reported issues are listed below.
Rod bearings failed due to a manufacturer defect. Many BMW M3's suffer this issue because if the tightness of the engine which leads to oil starvation and metal shavings begin to destroy the engine. The vehicle was in motion, after sitting for a few hours, I start the car to discover a ticking noise in the engine. Upon checking the oil, I have found metal shavings in the oil.
Loud knocking noise and a ticking noise that whined up when accelerated and slowly whined down when the accelerator is released. It appears to be bad rod bearing and it occurred within an hour of an oil change at the dealership. According to online forums this is not an uncommon occurrence.
