On a flat road, you can hear the "gurgling" sound in the front of the vehicle, which is intensified when turning sharply. When stopping for inspection, press and hold the front of the vehicle firmly to make it bounce up and down, and the abnormal noise occurs. The greater the force, the greater the noise.
Diagnosis 1: The electric butterfly valve is damaged due to oil leakage due to improper maintenance when the vehicle is usually driven on bad roads. Solution: In this case, repair or replace it according to the severity of the damage.
2. Oil leaks from the oil seal on the upper part of the main body of the electric butterfly valve. Once the electric butterfly valve moves, the oil drops more severely. Diagnosis II: The oil seal is damaged due to the damage of the piston rod or foreign matters, which results in the loss of sealing performance.
Solution: In this case, we recommend replacing new parts or new electric butterfly valves.
3. When starting or braking, the body bumps violently up and down, which makes the passengers feel unstable.
Diagnosis 3: The electric butterfly valve is old and aging.
Solution: We recommend replacing the electric butterfly valve to make the body feel bumpy up and down, reduce small vibration, and make the ride more stable and comfortable.
The electric butterfly valve is usually checked every 100000 km. The maintenance cycle of different models may be slightly different. When your car needs to be replaced and maintained, please know through the "Self service" function.
