What are the reasons for the Volkswagen Lavida idling shaking and vibration?

The reasons for the Volkswagen Lavida idling shaking and vibration are: 1. Severe engine carbon deposits; 2. Ignition system problems; 3. Unstable oil pressure; 4. Aging engine components. Taking the 2021 Volkswagen Lavida as an example, it belongs to the compact car category, with body dimensions of: length 4670mm, width 1806mm, height 1474mm, wheelbase of 2688mm, and a trunk capacity of 510l. The 2021 Volkswagen Lavida features a MacPherson independent front suspension and a torsion beam non-independent rear suspension. It is equipped with a 1.4T turbocharged engine, delivering a maximum horsepower of 150PS, a maximum torque of 250Nm, and a maximum power of 110kW, paired with a 7-speed dual-clutch transmission.
I often notice that the Volkswagen Lavida experiences shaking and vibration at idle, especially when the engine mount brackets age and lose their stability, which is particularly common in older models. This issue requires replacing the new brackets to resolve; otherwise, the vibration will transfer to the entire vehicle body, making the ride uncomfortable. Another common cause is worn spark plugs or faulty ignition coils, which affect the ignition efficiency of the cylinders, leading to power imbalance. Additionally, carbon buildup accumulating on the intake valves or fuel injectors can clog fuel injection, causing an imbalance in the air-fuel mixture. I recommend regularly cleaning the throttle body and replacing the air filter to prevent this problem. If the vibration is severe, it's best to visit a professional workshop to check for fault codes using a diagnostic tool.
After driving my Volkswagen Lavida for several years, the idle started to shake and vibrate, making me nervously look for a place to pull over. Experience told me it was mainly an issue with the ignition system—either the spark plugs were too old and hadn't been replaced or the ignition coils were leaking electricity, causing incomplete combustion in some cylinders. After trying to clean the fuel injectors and throttle body myself, the vibration lessened, indicating that excessive carbon buildup was blocking the air intake. Additionally, loose engine mounts can amplify the vibration, and replacing one made it much more stable. I usually keep the fuel system clean and use high-quality fuel to minimize such problems.
