You cannot continue driving with a damaged ignition coil. The reasons are as follows: 1. Engine vibration: If the ignition coil is damaged, the spark plug cannot ignite the combustible gas mixture, which can easily cause the engine to misfire and produce severe vibrations. If too many cylinders misfire, the engine may not start normally. 2. Increased fuel consumption and reduced power: Due to the weakened sparking ability of the spark plug, the combustion of the combustible gas mixture in the engine will be affected, leading to adverse reactions such as increased fuel consumption and reduced power. 3. Excessive carbon buildup: When the spark plug's sparking ability weakens, it can also cause incomplete combustion of the combustible gas mixture. This incomplete combustion produces a substance called carbon deposits, and the vehicle's exhaust may emit black smoke.

As a veteran driver with decades of experience, I've encountered situations where the ignition coil failed. At that time, the car shook violently at idle, had poor acceleration, and the fuel consumption was unusually high. I know it's possible to drive short distances, like from the workplace to the repair shop, without major issues. But never attempt long-distance travel or high-speed driving, as this can lead to misfiring, damaging the catalytic converter or even the engine itself. Once the ignition system fails, it gradually worsens, so I always make sure to have a professional replace the ignition coil as soon as possible. It's not expensive, usually costing just a few hundred yuan. Remember, if you experience similar symptoms, don't delay treatment to avoid turning a minor issue into a major one, affecting driving safety. Regular maintenance checks can prevent these problems from occurring.

What is the method to check the transmission oil level in a Volkswagen CC?

To check the transmission oil level in a Volkswagen CC, follow these steps: 1. Preheat the oil to approximately 50 degrees Celsius. 2. Shift the gear lever through each position, pausing for a few seconds in each gear, then check the oil level using the dipstick located on top of the transmission. The functions of transmission oil are: 1. To keep the shifting system clean; 2. To lubricate the transmission components. Taking the 2021 Volkswagen CC as an example, it is a mid-size sedan with the following dimensions: length 4865mm, width 1870mm, height 1459mm, wheelbase 2841mm, fuel tank capacity 66 liters, trunk capacity 501 liters, and curb weight 1640kg.

What Causes the Rattling Noise When a Camry Drives on Bumpy Roads?

The rattling noise when a Camry drives on bumpy roads can be caused by various reasons. Here are the detailed explanations: 1. Insufficient Body Rigidity: Rattling noises in the body often occur due to insufficient body rigidity, which causes the vehicle to deform during driving, leading to friction or shaking between doors and door frames, or even friction between steel plates due to welding failures. This is primarily a quality and manufacturing issue, with no fundamental solution. However, some rattling noises may result from loose body components, which can be fixed by tightening screws or replacing adhesive strips. Applying adhesive strips on windows or placing rubber pads in friction-prone areas might reduce or eliminate the noise, but these are temporary fixes. 2. Engine Vibration: Some engine noises are normal, but certain unusual sounds may indicate potential faults. For example, a high-pitched belt squeal is usually caused by belt slippage; sharp metal friction sounds during engine operation may stem from damaged bearings in the generator, water pump, or power steering pump, or from loose fasteners. A hissing sound could indicate an exhaust system blockage, vacuum tube leak, or breakage. Heavy metallic knocking sounds suggest engine knocking, often caused by excessive ignition advance angle, excessive carbon buildup in the combustion chamber, low spark plug heat range, or the use of low-quality gasoline. 3. Tire Noise: If you hear a "tapping" sound while driving, it might be due to a stone stuck in the tread or a punctured tire. A dull "rumbling" sound accompanied by tire and body shaking indicates uneven tire wear, requiring tire replacement. Overinflated tires can also cause excessive tire noise.
