Can You Continue Driving When the Engine Fault Light Is On?

You should not continue driving when the engine fault light is on. The reasons for the engine fault light being illuminated are: 1. Poor gasoline quality leading to incomplete combustion of the air-fuel mixture in the cylinder, resulting in carbon deposits; 2. Excessive engine mileage causing weakened spark plug performance; 3. Aging of vehicle mechanical components; 4. Damage, poor contact, or signal interruption to sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors. The hazards of an illuminated engine fault light include: 1. Deterioration of vehicle exhaust quality, leading to environmental pollution; 2. Increased combustion chamber temperature and accelerated wear, causing premature engine damage; 3. Engine oil burning; 4. Increased engine noise, affecting driving and passenger comfort.

What Causes Bubbles in Rear Windshield Tinting?

Rear windshield tinting may develop bubbles due to the following reasons: Impact of Heating Elements: The rear windshield contains numerous heating elements, which can affect the tinting to some extent. The presence of these heating elements causes the tint film to heat up when the rear windshield is warmed, leading to bubble formation. If there are numerous large bubbles, it is advisable to remove and reapply the tint film. Effect of Low-Quality Film: Over time, low-quality tint films exposed to UV rays may release toxic gases like formaldehyde, resulting in bubble formation. If bubbles appear due to this reason, it is necessary to replace the car's tint film immediately, as continued use can pose health risks.
