2001 bmw x5 speedometer not working
The BMW x5 dashboard turns red and can't afford to speed up because the acceleration logic of the automatic transmission is downshifting. If you want to speed up quickly, you can use the accelerator first to release the accelerator and then step on it. The acceleration is very fast. It's really not possible to have a sports gear. I don't know whether you have a self-priming or a t gear. I am self-priming. As long as you give fuel, acceleration is OK.
1 The area between the two red lines of the dashboard is the economic speed. In addition, if you accelerate, you can definitely add floor oil when stepping on it.
2 The red car sign on the instrument panel is the warning light of the driver's auxiliary anti-collision warning system. Its lighting up means that the car is too close to the vehicle in front of it and there is a risk of rear end collision. The red car sign is lit up to remind the car to keep a safe distance from the vehicle in front and ensure the safety of the car when driving
3 The working principle of the car anti-collision warning system is relatively simple. The front of the car is equipped with a radar, which can detect the distance between the car and the car in front. When the distance between the two cars is too close, the speed of the car behind is faster than the car in front, and the distance between the two cars is gradually shortened in a short time, the instrument will display a red car pattern to remind the owner.
4 If the red car sign flashes with a drip sound, it may be that the relative speed between the two cars is too fast, which causes the system to issue a more serious warning. Occasionally, it may also cause the collision warning system to automatically brake. At this time, the owner can stop the automatic braking behavior of the system by stepping on the accelerator or turning the steering wheel.The function of the air circulation pressure reducing valve of the turbocharger is to avoid severe vibration of the pump wheel of the turbocharger when the throttle valve is suddenly closed (for example, during gear shifting and when the accelerator pedal is suddenly loosened), which may cause damage to the turbine blades. The circulating air pressure reducing valve is opened to generate an air circulation around the turbine. The boost pressure is channeled to the inlet side of the turbine, which can connect the inlet side with the pressure side for a short time. After replacing the circulating pressure reducing valve, the test run is accelerated and the fault is solved.
