Can You Still Drive When BMW Shows Abnormal Engine Power Reduction?

[Legolas]

Automobile engine power reduction may be caused by excessive carbon deposits inside the engine that have not been cleaned, leading to poor airflow in the engine intake system and preventing the engine from functioning normally. In this case, you can continue driving as long as you perform cleaning afterward, which should not pose significant issues. Clogged Air Filter: The engine's intake system mainly consists of an air filter and an intake duct. Depending on usage conditions, the air filter should be cleaned regularly. One method is to use high-pressure air to blow dust out from the inside to the outside. Since the air filter is made of paper, be cautious with the air pressure during cleaning to avoid damaging the filter. Generally, the air filter should be replaced after being cleaned three times, and the cleaning cycle can be determined based on the air quality of your usual driving area. Dirty Intake Duct: If the vehicle frequently operates in areas with high dust levels or poor air quality, attention should be paid to cleaning the intake duct to ensure smooth airflow. The intake duct is crucial for the engine's normal operation. If it becomes too dirty, it can reduce charging efficiency, causing the engine to operate outside its normal power range and accelerating engine wear and aging.
