What are the symptoms of a bad dual-clutch clutch plate?

Symptoms of a bad dual-clutch clutch plate include clutch slippage, etc. Symptoms of a bad clutch plate: A burning smell can be detected, the clutch plate slips, acceleration is weak, and power performance declines; when the friction plate is damaged, it results in slipping during startup or weak driving performance, where the engine speed increases but the vehicle speed does not. The relationship between the pressure plate and the friction plate is interdependent. When the friction plate is faulty, it accelerates the wear of the pressure plate and even the flywheel. The main symptoms include difficulty in shifting gears, incomplete disengagement, and shaking during startup. Possible causes of a bad dual-clutch plate may include: Improper operation by the driver can cause the clutch plate to rub against the pressure plate and flywheel, generating high temperatures that can burn out the clutch plate; when the driver operates the clutch pedal, the clutch plate and pressure plate may suddenly engage, easily causing the clutch plate to break down and the pressure plate surface to wear; the clutch plate may naturally age and wear out due to prolonged use or excessive mileage.
My car previously experienced issues with the dual-clutch clutch plate damage. The most noticeable symptom was severe jerking during low-speed city driving, especially when following traffic. Every shift from first to second gear had a distinct tugging sensation, as if being lightly kicked. Additionally, during acceleration, the engine RPM would spike rapidly, but the car lacked power to move forward effectively, as if most of the power was being lost. Once, I even smelled a burning odor while going uphill, which later turned out to be caused by overheating of the clutch plate. Restarting after stopping was even more frustrating, occasionally causing violent shaking that made the entire body tremble. These are all classic signs of clutch plate wear. If not addressed promptly, not only does fuel consumption skyrocket, but in severe cases, the car might even break down on the road.
When the clutch discs of a dual-clutch transmission develop issues, several key symptoms are worth noting. A metallic grinding sound is often heard during gear shifts, particularly noticeable when downshifting from third to second gear. While driving normally, there may be sudden moments of power interruption lasting less than a second but quite alarming. The car drives exceptionally smoothly for the first five minutes after a cold start, but begins to slip once warmed up. Although no warning lights appear on the dashboard, the vehicle's performance is abnormal. Fuel consumption increases by 20-30% compared to normal due to reduced power transmission efficiency. Such problems typically progress from occasional occurrences to becoming constant. It's advisable to have the clutch assembly inspected immediately if more than three symptoms are observed, rather than waiting until complete failure occurs.
