Why is the secondary air system air flow too low in Mercedes-Benz?

[Tracey]

Mercedes-Benz secondary air system air flow is too low due to secondary air injection failure. When the engine is in a hot state, never open the radiator cap, otherwise you may be scalded by splashing coolant or high-temperature steam. The brake fluid level between high and low indicates normal. A normal spark plug has intact insulation ceramic. How to use Mercedes-Benz shift paddles: The shift paddles in Mercedes-Benz are located below the steering wheel, with one paddle on each side of the steering wheel. The left paddle is for downshifting, usually marked with a "-" sign, and the right paddle is for upshifting, usually marked with a "+" sign. While driving, the shift paddles rotate with the steering wheel, making it convenient to shift up or down. Tips for using Mercedes-Benz shift paddles: When driving and needing to overtake the car ahead, you can downshift using the paddles, then increase the throttle to raise the RPM and boost torque for quick overtaking. When driving on mountain roads or on a track, you can downshift before entering a curve, allowing for greater torque when exiting the curve, enabling the car to accelerate faster.
