What are the causes of engine shaking in BMW X1?
2 Answers
The causes of engine shaking in BMW X1 are as follows: 1. Severe engine carbon deposits: Clean the fuel system and check if the idle speed motor has carbon deposits that should be cleaned. It is recommended to use BOD's 'Fuel System Cleaner', which can be added to the fuel tank when refueling to achieve the effect of cleaning the fuel system. 2. Ignition system problems: Check if the spark plugs have excessive carbon deposits and replace them if necessary. 3. Unstable oil pressure: Check the oil pressure and replace components if necessary. 4. Aging engine components: Identify and replace aging components. The air filter is directly related to the engine's air intake during driving.
I previously drove a BMW X1 and encountered engine vibration issues. At that time, I found that carbon buildup was quite severe, especially around the throttle body and spark plugs where excessive dirt accumulation caused poor air intake, leading to constant engine shaking during idle or acceleration. Check the condition of your spark plugs—if they're worn out from prolonged use or have excessive gaps, unstable flame during ignition can also cause vibrations. Additionally, if the air filter is clogged or dirty, insufficient air intake can make the engine run unevenly. I recommend using high-quality fuel additives to clean carbon deposits regularly and cleaning the throttle body every 20,000 kilometers to prevent carbon buildup. It's best to schedule regular inspections at a 4S shop. If noticeable vibrations occur, don't delay addressing them, as this could affect engine longevity and may also waste fuel.
