Why does the Sagitar's engine fault indicator light come on and the vehicle shake?
2 Answers
Sagitar's engine fault light comes on and the vehicle shakes due to internal engine failure or poor combustion. Here are the solutions for engine fault light illumination and vehicle shaking: Dirty throttle body: For a dirty throttle body, it is recommended to clean the throttle body every 20,000 to 30,000 kilometers. Carbon deposits on valves and fuel injectors: For carbon deposits on valves and fuel injectors, it is recommended to clean the intake and fuel system every 30,000 to 40,000 kilometers. Substandard fuel quality: For substandard fuel quality, it is recommended to add some high-quality fuel additives after refueling or choose gas stations with good fuel quality to improve fuel quality.
My car is from the Volkswagen family, so I'm quite familiar with issues like the engine malfunction indicator light coming on and shaking in the Sagitar. The most common cause is ignition system failure, such as aging spark plugs or damaged ignition coils, which can prevent a cylinder from firing, leading to uneven engine operation and severe body shaking. That warning light usually comes on when the onboard computer detects abnormal signals, triggered by issues like oxygen sensor or crankshaft position sensor malfunctions. I recommend you promptly visit an auto repair shop to read the fault codes with an OBD scanner for precise problem identification. Don't delay driving it, as it might cause catalytic converter damage. Such situations are more common in older or poorly maintained vehicles, and regular inspection of ignition components can effectively prevent them.
