Common issues after cleaning fuel injectors include engine shaking and increased fuel consumption. Below are detailed solutions: Handling Engine Shaking: The vehicle's onboard computer has a self-learning function, and the fuel injection data before cleaning is stored in the ECU. After cleaning, the throttle continues to use the data from when it was clogged, leading to unstable idle and severe shaking due to the higher throttle opening. Simply resetting the throttle opening to factory settings can resolve this issue. Increased Fuel Consumption: After cleaning the throttle, fuel consumption may noticeably increase for a short period. This can stabilize over time or be resolved by resetting the computer. Some vehicle models require connecting to a maintenance computer via the onboard OBD interface to perform the reset.

Why is left turn allowed at red light?

Motor vehicle traffic signals and non-motor vehicle traffic signals indicate: When the green light is on, vehicles are permitted to pass, but turning vehicles must not hinder the passage of through vehicles and pedestrians; When the yellow light is on, vehicles that have already crossed the stop line may continue to pass. When the red light is on, vehicles are prohibited from passing. At intersections without non-motor vehicle traffic signals or pedestrian crossing signals, non-motor vehicles and pedestrians should follow the motor vehicle traffic signals. Additional information: Pedestrian crossings, overpasses, or underpasses should be installed at road intersections and sections with concentrated pedestrian crossings. In sections with frequent blind pedestrian traffic, audible signal devices should be installed for pedestrian crossing signals.

How to resolve the P0513 fault code?

P0513 fault code indicates an incorrect anti-theft key, meaning the anti-theft controller has detected an issue with the key. The function of the anti-theft control module is to ensure the car can only start when the dedicated key is present and matches with various components. If a problem occurs, it should be addressed promptly at a professional service center. Based on the fault system principle and an analysis of potential causes, the following components should be checked: 1. Check if the battery voltage is too low. 2. Verify if the key chip is faulty. 3. Inspect the anti-theft read coil for any faults. 4. Examine the anti-theft controller (IMMO) and its power supply circuit. 5. Check the engine control system.

What to Do About Minor Paint Scratches?

Here are the solutions for minor paint scratches: 1. For deeper scratches, you can use a touch-up pen of the same color to cover them, but this is only a temporary and less aesthetic solution. If the scratches are deep enough to expose the metal, it is recommended to repaint the affected area. 2. For shallow scratches or minor surface marks, you can use car wax to polish and buff them out. This method usually blends well with the original paint without noticeable differences. When touching up paint, first choose a color that closely matches your car's original shade. Secondly, perform the touch-up on a sunny, dry day and preferably in the shade. Thirdly, ensure the scratched area is thoroughly cleaned before treatment. Finally, avoid washing the car for at least three days after completing the touch-up.

Mercedes-Benz GLA One-Touch Window Control

Hold down the lock button on the car key, and all window glasses will simultaneously rise. Similarly, holding down the unlock button will cause all window glasses to lower simultaneously. Below is additional information about one-touch window control: 1. One-touch window control refers to a system where car window glass can be fully raised or lowered with a single press of a button. Cars equipped with this feature have two-stage window control switches. The first position functions like a regular power window, while the second position allows the window to automatically open or close completely with just one press and release. 2. Generally, mid-to-high-end models come with one-touch window control, mainly for the convenience of drivers and passengers, avoiding distractions from manually operating windows and improving safety. One-touch windows usually feature an 'anti-pinch' function to prevent the risk of pinching fingers.

Can the Engine Be Started Again After Water Ingestion?

Engine water ingestion prohibits restart attempts, as secondary ignition may lead to the following scenarios: 1. The engine may initially start post-water exposure, but with water entering the air filter. The engine inhales moisture-laden air, forming steam. When water vapor mixes with gasoline for complete combustion, the impact on the engine remains minimal; 2. Minor water ingress reaching the cylinders contaminates engine oil, degrading its quality. Water-contaminated oil accelerates engine component wear, manifesting as increased noise and vibration during operation; 3. The most severe scenario occurs when the engine stalls seconds after starting and becomes inoperable despite multiple attempts. Since water is incompressible, its presence in cylinders during high-speed operation can bend valves/connecting rods, seize pistons, severely score cylinder walls, and warp crankshafts.

Where to Add Cleaning Fluid in a Mercedes-Benz?

Mercedes-Benz cleaning fluid is added at the windshield washer fluid filling point in the engine compartment. Steps to add Mercedes-Benz cleaning fluid: First, press the engine compartment unlock button in the cabin to unlock the engine compartment. Then, pull the lever at the front of the engine compartment hood to open it. This will reveal the windshield washer fluid filling location in the engine compartment where you can add the fluid. Function of automotive cleaning fluid: When the cleaning fluid comes into contact with dirt particles on the car's surface, the strong wetting force of the cleaning solution allows it to easily wet the surface of the object being cleaned, ensuring thorough contact between the two. The solution deeply penetrates the surface of the dirt particles and the tiny gaps within dirt aggregates, effectively wetting them. This process weakens and loosens the bond between the dirt and the cleaned surface.
