Mercedes-Benz C180 boost pressure deviation from the standard value is a comprehensive fault, with the main cause being the decrease in turbocharger rotor speed. The following are detailed reasons: 1. Speed: Generally, when the engine operates at the rated speed (above 2500 rpm), the turbocharger rotor speed reaches as high as 150,000 to 200,000 rpm, allowing the boost pressure to reach the rated value. 2. Bearing damage: When the bearing and shaft wear out, the turbine or pump wheel blades deform or get damaged, or when the rotor rubs against the housing, causing the rotor speed to decrease, the boost pressure will consequently drop.

Does Slight Water Wading Have a Significant Impact on Cars?

Car slight water wading has little impact. Here is a detailed introduction to the effects of car wading: 1. Headlights: Water vapor may form inside the headlights, affecting the light transmission effect. 2. Vehicle chassis: Dirt can adhere to the chassis or gaps under the body, leading to rust on the chassis. 3. Air filter: Water may enter the engine through the air intake. 4. Brake pads: After wading, it is essential to remove water from the brake pads, especially for cars with drum brakes, otherwise, the vehicle may lose braking ability after wading, causing severe danger or accidents. 5. Wiring harness connectors: Different types of wiring harnesses in the engine compartment are positioned at varying heights. In the future, the car's electrical system may experience occasional faults.

Can the car still be driven with an engine temperature of 130 degrees?

An engine temperature of 130 degrees means the car should not continue to be driven and requires immediate inspection and repair. Below are the common causes of high engine temperature: 1. Coolant issues: The coolant may have reached its replacement interval or deteriorated; there might be a coolant shortage; or the coolant circulation system could be blocked. Regularly check the vehicle's coolant level and inspect the circulation system. 2. Engine issues: The engine thermostat might be damaged; this issue should not be overlooked and must be repaired promptly to avoid affecting engine performance. 3. Radiator issues: The radiator fan might be damaged; regularly inspect the vehicle's radiator fan.

If dashed yellow lines are used, it means temporary parking is allowed, but vehicles cannot be parked for too long. Yellow grid lines: If there are yellow grid line areas on the road, parking is prohibited within these areas, including temporary parking. White guide lines: In urban central areas or at highway ramp intersections, white guide lines are usually present, which also indicate no-parking zones.

What to Do About Rusty Car Brake Discs?

Here are the methods to deal with rusty car brake discs: 1. If the rust is only slight, you can use continuous braking while driving to remove the rust. Disc brakes rely on friction between the brake caliper and brake pads, and the rust can wear off after multiple braking applications, but this should be done in a safe area. For areas of the brake disc that are not worn down, you can remove the wheel and lightly sand the brake disc with fine sandpaper. 2. If the rust is severe enough to cause noticeable vibration in the brake pedal or steering wheel when braking, you should contact an authorized service station for assistance. Stubborn rust not only cannot be polished away but will also accelerate the wear of the brake pads.

What are the inspection items for the engine compartment?

The inspection of the engine compartment is divided into three parts. Check the wiring: After opening the engine hood, carefully inspect whether the wiring in the engine compartment is neat and uniform, whether there are signs of component disassembly, and whether there are oil stains on the terminal posts. Check for deformation: Inspect whether the upper edge of the engine hood is smooth. There are some single-plate holes on the engine cover; make sure to check for any deformation. If deformation is found, it indicates that the hood has undergone reshaping and repainting. Check for loose screws: Examine whether various screws are loose or missing, check if the frames of different parts are smooth, and ensure that the gaps are evenly spaced.
