What is the reason for the lack of power when starting with a newly replaced clutch?

Just replaced clutch lacks power when starting due to the clutch being too high. Here are the specific details about the car clutch: 1. Clutch too low: The free travel of the clutch will be very long, and the working travel will be relatively short, which will prevent the engine and transmission clutch plate from completely separating, keeping the vehicle in a semi-engaged state. 2. Clutch too high: This leads to a longer working travel and shorter free travel, making the vehicle prone to stalling while driving. At the same time, the clutch pedal will become very heavy, making it more strenuous for the driver to operate. Prolonged low-speed following will cause the driver to lose too much energy.

What are the reasons why the Mercedes-Benz one-button start fails to ignite?

The reasons why the Mercedes-Benz one-button start fails to ignite are as follows: 1. The smart key is out of battery: When the vehicle's smart key is out of battery, the key's transmission power is very low, making it difficult for the vehicle's sensor to detect it. 2. The gear is not in P position: If the vehicle can be started directly in D or R gear, the sudden movement of the vehicle at the moment of ignition is undoubtedly a significant safety hazard. 3. The steering wheel is locked: Steering wheel lock is a simple anti-theft function. When the car is turned off, turning the steering wheel a certain angle from the straight position in one direction will cause the steering wheel to lock with a click. In the locked state, the one-button start function will not work.
