What causes the abnormal noise when accelerating in a Mercedes-Benz GL350?
1 Answers
Abnormal noise during acceleration may be caused by brake lock-up, transmission issues, or solenoid valve problems. Brake lock-up: Brake lock-up prevents the wheels from moving forward, resulting in abnormal noise when accelerating. Transmission issues: Insufficient transmission fluid, low internal oil pressure, or internal transmission problems. The transmission is a gearbox that changes the transmission ratio and direction of motion. Located between the clutch and the central drive, its main functions are gear shifting, reversing, and neutral. Transmission problems can prevent the vehicle from starting. Solenoid valve problems: Incorrect gear signals, issues with the shift solenoid valve wiring, or the solenoid valve itself may be faulty.
