CDC (Continuous Damping Control) damping valves are electronically controlled shock absorbers used in automotive suspension systems. Under normal usage conditions, they generally do not require regular replacement. However, based on factors such as the actual wear of the shock absorbers and the vehicle's mileage, inspections and maintenance may be necessary within certain periods.
Generally speaking, if you notice any of the following issues with your vehicle's suspension system, it may be time to consider replacing the CDC damping valves:
Oil leakage from the shock absorber: If the shock absorber leaks oil, it will lead to reduced or even lost damping effect, necessitating replacement of the shock absorber.
Excessively fast spring rebound: When driving over bumpy roads or at high speeds, if you feel that the vehicle's springs rebound too quickly, it may indicate a decline in shock absorber performance, and replacement should be considered.
Abnormal bumping, bouncing, or instability during driving: If you experience abnormal operation of the vehicle's suspension system while driving, such as bumping, bouncing, or instability, it may be due to damage or excessive wear of the shock absorbers. Inspection and replacement are recommended.
High vehicle mileage: Generally, when a vehicle's mileage reaches over 100,000 kilometers, the shock absorbers may start to age or experience performance decline. It is advisable to conduct inspections and, if necessary, replacements.
In summary, the need to replace CDC damping valves should be determined based on actual circumstances. It is generally recommended to regularly inspect the vehicle's suspension system and decide on replacement based on the working condition and performance of the shock absorbers. If significant issues with the shock absorbers are identified, prompt replacement is recommended to ensure driving safety and comfort.
