Audi A4L New Car Engine Noise is Loud

[GiaAnn]

Audi A4L new car's engine during the break-in period may produce some noise because it is not fully broken in. If the noise is quite loud, it is advisable to consult a 4S dealership to ensure the car operates normally during the break-in period, preventing any abnormal engine conditions that could lead to excessive wear and affect the engine's normal service life. During the break-in period, avoid prolonged high-speed driving as it causes the engine to operate at high RPMs, which can easily lead to engine overheating and exacerbate abnormal wear. High-speed driving should not exceed three hours; necessary stops for rest allow the engine to fully dissipate heat.
