Reasons for idle vibration in a BMW 5 Series 6-cylinder engine: 1. Severe engine carbon buildup; 2. Dirty throttle body or excessive carbon deposits in the fuel injectors; 3. Faulty spark plugs, high-voltage wires, or ignition coils leading to poor ignition system performance; 4. Unstable oil pressure, insufficient fuel pump pressure, or incorrect readings from the intake pressure sensor; 5. Fuel line blockage causing inadequate fuel supply; 6. Aging engine components. In terms of exterior design, the BMW 5 Series features a one-piece large-size kidney grille for a more imposing presence. The adaptive LED headlights with BMW Dynamic Beam technology replace the hexagonal design with a simple and slender horizontal L-shaped light strip, complemented by BMW Intelligent Laser Headlights with blue lasers, exuding a dynamic and spirited look.

Do Electronic Eyes Capture Turn Signals?

Electronic eyes do not capture turn signals. The electronic surveillance systems on roads are designed to record traffic violations committed by motor vehicles, including crossing the line, running red lights, failing to yield to pedestrians, driving outside designated lanes, and illegal parking, among other traffic violations. More relevant information is as follows: Handling of Violations: Traffic violations captured by electronic surveillance can be processed through mobile apps like Traffic Management 12123, or directly at the vehicle management office or traffic authorities. Regardless of the method chosen, the violations can be effectively handled without any impact. Latest Processing Time: The latest time to process traffic violations is before the vehicle's annual inspection. If violations are not addressed, the vehicle cannot undergo the annual inspection procedure. Vehicles that fail to complete the annual inspection are not permitted to drive on the road, as doing so constitutes a legal violation.

What does it mean when the car displays TC?

The car displaying TC refers to the Traction Control system. When the system is active, the yellow TC light on the dashboard flashes to alert the driver. The Traction Control system, also known as the Track Control system, relies on electronic sensors to detect if the driven wheels' speed is lower than that of the driving wheels. It then sends signals to adjust ignition timing, reduce throttle opening, decrease fuel supply, downshift, or apply braking to the wheels to prevent wheel slip. Possible causes for the TC light to illuminate include: 1. Solenoid valve malfunction; 2. Dirty engine oil clogging the solenoid valve filter; 3. Wear in the actuator gears or impeller causing oil pressure leakage and triggering the alarm; 4. Dirty throttle body with opening reaching 20%, leading the engine computer to misdiagnose a TC fault.
