mini cooper tachometer not working

• 2022-10-18

If mini cooper tachometer does not move: if it is a mechanical tachometer, the transmission core wire may be broken. Solution: replace a transmission core wire; It is also possible that there are foreign matters stuck in the meter. It is enough to remove the foreign matters by disassembling the meter. There are foreign matters in the instrument panel, which prevent the pointer in the tachometer from rotating. If the tachometer pointer is stuck or dropped, the tachometer will not move. If the circuit in the tachometer fails, it may be burnt or aging. If the flexible shaft in the tachometer breaks or cannot be connected, the tachometer will not move.

If there are foreign matters in the tachometer, it is only necessary to remove the instrument panel and clean up the foreign matters. This does not require money. If there are other problems, the car owner can only go to the 4S store or the maintenance shop to find professional personnel for maintenance.

When the vehicle is not running, it will be idle. At this time, the pointer of the tachometer is not at 0, but at a position above 700 revolutions. Therefore, at any time, it is impossible to determine whether the vehicle has started, just look at the tachometer. In the past, many people would shift gears according to the sound of the engine, but now, with the sound of the whole vehicle getting better and better, the sound of the engine is basically inaudible. The most correct method is to determine according to the speed of the engine. You can know the shift time by looking at the tachometer. There is a red area on the tachometer. Generally, the speed in the red area will be above 6000 rpm. For the engine, maintaining a high speed for a long time will cause poor lubrication performance of the engine, and the burden of the cooling system is also relatively large. If the engine is in the red zone for a long time, all parts of the engine will be damaged to a certain extent. Therefore, the condition of the engine can be judged according to the safe area of the engine tachometer.

The function of the engine tachometer is to reflect the problems of many cars. Many experienced drivers or maintenance technicians can judge whether the car has problems, such as carbon deposition, throttle valve, spark plug, ignition coil, etc., by the movement of the tachometer pointer when the engine is idling.
