Z4 gear indicator is always on.

The reasons why the Z4 gear indicator is always on are as follows:

1. Road conditions may cause the automatic transmission oil to overheat or the automatic transmission oil to be too dirty, which may cause the sensor to transmit wrong information;

Second, the gear switch is damp and slightly corroded, resulting in poor contact;

Third, the gearbox pressure causes the sensor to fail;

Four, the electronic control unit, dial wiring and related components have scratches, burns or poor contact;

Five, clutch friction plate wear or insufficient pressure. When the friction surface of the clutch falls off, the directly related parts of the gearbox electronic components are damaged, resulting in the damage of the gearbox computer.

Solution:

It is recommended that the owner go to the 4s shop, use a professional computer to detect the faulty parts of the transmission, and then replace the damaged parts. When the clutch and the valve body are worn, the worn debris may block the battery valve, causing the battery valve to get stuck, so that the signal of the battery valve cannot be processed by the gearbox computer. This situation may cause the car to malfunction, such as low signal and short circuit to ground. If the transmission fails, it is necessary to check the idle speed of the automobile engine and adjust the throttle.

BMW Z4:

1, BMW Z4 is a BMW coupe. The design of Z4 is improved on the basis of Z3, with a long hood and a very comfortable seat, which almost falls on the rear axle. The sloping tail of the new car is more attractive, and the concave and convex lines on both sides make the new car look more domineering than the Z3.

2. Although Z4 doesn't have a fixed roof, compared with most hardtop cars today, passengers feel less psychological pressure when an accident occurs. Z4 not only won the highest honor of safety, but also has the best deformation resistance, which is an important guarantee for the sports characteristics of BMW Roadster.

3. The sales volume of BMW Z4*** is 23,374, which is the most successful model in the world's high-end single-row convertible category. Z4 was listed in June 2002, and has maintained a leading position in the market ever since.
