The reasons for the ticking sound in BMW's N20 engine are: 1. Severe carbon buildup in the engine; 2. Unstable oil pressure; 3. Aging of engine components; 4. Poor performance of the ignition system, causing spark plug misfire. Taking the BMW 120i as an example, it is a 4-door, 5-seater compact sedan with body dimensions of: length 4462mm, width 1803mm, height 1446mm, and a wheelbase of 2670mm. The BMW 120i is equipped with a 1.5T turbocharged engine, paired with a 7-speed dual-clutch transmission, delivering a maximum power of 103 kW and a maximum torque of 220 Nm.
