What's wrong with the abnormal engine of BMW X1?
2 Answers
BMW X1 engine abnormal reasons are as follows: Internal carbon deposits: After a certain period of use, the engine will inevitably accumulate some carbon deposits. These deposits themselves will cause changes in the engine's design parameters, and their unstable nature and heat accumulation can lead to disorderly ignition of the engine, resulting in engine knocking. In this case, the engine fault light will come on. Poor combustion state: A poor combustion state is the main reason for the engine fault light to come on. In automotive design, to ensure the engine is in good working condition and to guarantee its normal working lifespan, an oxygen sensor is installed to monitor the engine's combustion state. Once the combustion state is poor, it not only causes environmental pollution but also leads to fuel waste and excessive engine wear.
I've driven the BMW X1 several times, and engine abnormalities are indeed quite common, mainly requiring checks on some basic components. The most frequent issue is ignition system failure, such as aging spark plugs or damaged coils, which can cause engine shaking and sluggish acceleration. There could also be fuel supply problems, like clogged injectors or a failing fuel pump, especially noticeable during traffic jams. Additionally, the electronic control unit is prone to bugs, and BMW's iDrive system sometimes falsely reports error codes—it's best to use an OBD scanner to read the fault codes. Engine overheating is another factor; check if the coolant and cooling fan are functioning properly. My advice is not to rush into long-distance driving; instead, take it to a professional repair shop for a thorough diagnosis to prevent minor issues from turning into major repairs. During regular maintenance, check the engine oil and air filter to prevent many problems. BMW engines have high maintenance requirements, so don't skimp on these costs.
