What is the reason for the functional failure of the Mercedes-Benz inflatable sport air flap cylinder?

[DiNova]

The reasons for the functional failure of the Mercedes-Benz inflatable sport air flap cylinder include: excessive sludge accumulation in the internal oil passages of the vehicle's fuel injectors, leading to blocked and insufficiently smooth fuel lines, preventing adequate fuel from entering the combustion chamber. Cleaning the vehicle's fuel injectors can eliminate this fault. Check whether the oil level in the float chamber is too high: If the oil level is normal, check whether the choke valve is open and whether the air filter is dirty or clogged. If the oil level is too high, adjust it. If the oil level cannot be adjusted to the normal height, check whether the needle valve is sealed and whether the float is broken. Check the carburetor: If the above checks are normal but the mixture is still too rich, check whether the main metering orifice of the carburetor is too large, whether the economizer is malfunctioning, and whether the air orifice is blocked. For carburetors with a main metering orifice adjustment needle, check whether the adjustment needle is unscrewed.
