What Causes the Vibration When the BMW X3's Air Conditioning is Turned On?

[LaAlyssa]

When the air conditioning is turned on in the BMW X3, the compressor also starts working. Since the compressor is driven by the engine, its operation increases the engine's load, leading to vibration. Throttle Body Not Maintained: If the throttle body is not maintained for a long time, carbon deposits can easily accumulate. Severe Carbon Buildup: Carbon deposits can obstruct the engine's air intake, causing the engine to struggle or barely manage to drive the compressor, resulting in idle vibration. Cleaning the Throttle Body: The throttle body needs to be cleaned. If the driving environment is harsh, it is best to clean it regularly, recommended every 10,000 kilometers.
