BMW key not working is caused by insufficient battery power in the key, and the key battery needs to be replaced as soon as possible. Car key lifespan: The battery in a car key generally lasts about two years. When the key battery power is too low, it will affect daily locking/unlocking and the normal starting of the vehicle. When the car key is unresponsive: Therefore, when the vehicle indicates low key battery power, or the remote control distance becomes shorter or less responsive, it may be due to low key battery power. In severe cases, the BATTERY (BATT) warning light on the instrument cluster will illuminate, at which point the key battery must be replaced.

What are the advantages of manual transmission over automatic transmission?

Here are the advantages of manual transmission over automatic transmission: Price: Compared to automatic transmission models with the same configuration, manual transmission models are often cheaper. The two cars have the same configuration, the same exterior and interior, except that the automatic transmission has additional features like tire pressure monitoring and cruise control, but otherwise there is no difference from the manual version. Manual versions also have cruise control. For example, the Chang'an CS15 manual versions all have cruise control except for the entry-level model. Performance: If the manual transmission itself is of good quality and used correctly, it is almost impossible to malfunction and has a long service life. As long as the owner is willing, even if the car is driven to scrap, there is no need to change the gear oil.

What Causes the Jerking Sensation When Letting Off the Throttle?

Here are the reasons for the jerking sensation when letting off the throttle: Poor coordination between throttle and clutch: If the throttle and clutch are not properly coordinated during gear shifting, the vehicle may exhibit noticeable sudden deceleration followed by sudden acceleration, which is the most obvious form of 'jerking sensation.' However, in automatic transmissions, since the gear shifts are controlled by the computer, theoretically, it should be smoother. But due to the structure of the transmission, the severity of the jerking sensation varies in automatic vehicles. Fuel octane rating issue: You can perform some simple checks yourself, such as whether the wrong fuel was added. This is a possibility because using lower octane fuel may result in sluggish acceleration, leading to reduced engine power and increased fuel consumption.
