How many kilometers is the break-in period for the Audi A5?

Audi A5 has a break-in period of 3,000 kilometers. When a car is newly acquired, the process of wearing off metal debris and burrs from the components is called break-in. Below are specific details regarding break-in period precautions: 1. Avoid emergency braking: Emergency braking not only harms the braking system during the break-in period but also increases the impact on the engine and transmission. 2. Do not drive at high speeds: Owners who tend to floor the accelerator should note that the engine has limited capacity; do not overload it. Try to keep the engine speed steady below 3,000 rpm. 3. Avoid overloading: Overloading makes steering heavy, increases centrifugal force, and affects the car's handling performance; long-term overloading also shortens the car's lifespan and accelerates component wear. Keep the total weight of the car and cargo within 70% of the rated load. 4. Use high-quality fuel: There are many types of fuel on the market; choose fuel that meets national standards, as substandard fuel can clog the fuel tank and lines. 5. Warm up the car before cold starts: Warming up the car: first, it ensures smooth engine startup; second, it effectively saves fuel; third, it reduces wear on moving parts. 6. Use the appropriate gear: Manual transmission owners, please note that the gear should match the engine speed—remember, high speed for high gear and low speed for low gear.

What does it mean when the engine malfunction indicator light flashes and there is shaking?

When the engine malfunction light is on and the vehicle body shakes, the cause is poor combustion of the air-fuel mixture. Poor combustion of the air-fuel mixture can lead to carbon buildup in the engine, which is the most significant reason for vehicle shaking. Additionally, when the oxygen sensor detects poor combustion and reports it to the ECU, the malfunction light is triggered as a warning. This is why the engine malfunction light and vehicle shaking occur simultaneously. Issues such as faulty spark plugs, defective ignition coils, malfunctioning fuel pumps, or clogged fuel lines can all cause poor combustion of the air-fuel mixture in the engine. If the engine malfunction light is on, follow these steps: First, check if the engine is running normally. Look for signs like shaking, black smoke emission, or difficulty starting. If any of these symptoms are present, avoid restarting the engine. Note: Do not restart the engine if the red warning light is on. If the engine is running normally and the vehicle can be driven, proceed to a service station as soon as possible to diagnose the issue. A service station can easily read the trouble codes using a portable diagnostic tool, allowing for targeted repairs based on the fault information. If the engine is running normally, the owner can also try gently reconnecting various wiring harness connectors, as a loose connection might be the cause. Alternatively, repeatedly turning the key to the ON position may help reset the system.

The Function of the Secondary Oxygen Sensor?

The secondary oxygen sensor, also known as the rear oxygen sensor, is responsible for detecting the oxygen concentration in the exhaust and sending feedback signals to the ECU. The ECU then adjusts the fuel injection volume of the injector to maintain the air-fuel ratio of the mixture near the theoretical value. The oxygen sensor in a car is a critical feedback sensor in the electronically controlled fuel injection system. It plays a key role in controlling vehicle exhaust emissions, reducing environmental pollution, and improving the combustion quality of the engine's fuel. Oxygen sensors are installed on the engine's exhaust pipe. If the oxygen sensor fails, the ECU of the electronic fuel injection system will not receive information about the oxygen concentration in the exhaust pipe, making it unable to perform feedback control on the air-fuel ratio. This can lead to increased fuel consumption and exhaust pollution, as well as engine issues such as unstable idling, misfires, and surging. Therefore, timely troubleshooting or replacement is essential. Cars are equipped with both front and rear oxygen sensors, which work in tandem. Below is an introduction to the front and rear oxygen sensors: 1. Front Oxygen Sensor: The front oxygen sensor typically has a 5-wire configuration. Its function is to provide feedback on the air-fuel ratio during engine operation. The optimal theoretical air-fuel ratio is 14.7:1. During operation, the engine injects fuel based on the calibrated MAP, striving to maintain the theoretical air-fuel ratio except under high load conditions. However, slight variations in fuel injection may occur during actual engine operation. In such cases, the engine can adjust the fuel injection volume based on the feedback from the front oxygen sensor to achieve the theoretical air-fuel ratio, thereby improving fuel efficiency and emission performance. 2. Rear Oxygen Sensor: The rear oxygen sensor typically has a 4-wire configuration and serves two purposes. First, it monitors the conversion efficiency of the catalytic converter to ensure that emissions do not fluctuate drastically. Second, it acts as a supplementary control for the front oxygen sensor in case the front sensor fails. Due to its operational characteristics, the rear sensor has minimal impact on short-term fuel injection adjustments but should be considered for long-term fuel injection corrections. The rear oxygen sensor is primarily used to monitor the conversion efficiency of the three-way catalytic converter, while the closed-loop control of the air-fuel ratio is managed by the front oxygen sensor. Therefore, as long as the front oxygen sensor is functioning properly, fuel consumption remains unaffected.

What does traffic violation code 1092 mean?

Violation code 1092 means: Passenger vehicles other than road passenger transport vehicles carrying goods in violation of regulations. Violated provisions: Article 49 of the Road Traffic Safety Law of the People's Republic of China: The number of passengers carried by a motor vehicle shall not exceed the prescribed number, and passenger motor vehicles shall not carry goods in violation of regulations. Article 54, Paragraph 2 of the Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China: For other motor vehicles carrying goods, the height from the ground shall not exceed 2.5 meters. Traffic violation codes consist of four to five digits, classified according to the principles in the traffic law. From left to right, the first digit represents the behavior classification code, the second digit represents the penalty point classification code, the third and fourth digits are sequential codes, and the fifth digit indicates the specific item number under that clause. The first digit: Behavior classification code, indicating the category in the Road Traffic Law; The second digit: Penalty point classification code, indicating the penalty points for the traffic violation; The third and fourth digits: Sequential code, indicating the order of the violation within the same behavior category. For example: 13035 - "1" indicates motor vehicle behavior, the second digit "3" means 3 penalty points, and "035" indicates the fifth item under the third clause in the 3-point penalty category. Behavior classification code violation descriptions: Codes starting with 1 indicate motor vehicle traffic, e.g., 1003; Codes starting with 2 indicate non-motor vehicle traffic, e.g., 2002; Codes starting with 3 indicate pedestrian or passenger traffic, e.g., 3030; Codes starting with 4 indicate highway traffic, e.g., 4002; Codes starting with 5 indicate other regulations, e.g., 5005; Codes starting with 7 indicate implementation rules of provinces, autonomous regions, or municipalities, e.g., 7008; Codes starting with 8 indicate local regulations of cities (prefectures, autonomous prefectures, or leagues), e.g., 8606. There are four common methods to query motor vehicle violations: Visit the office halls of traffic police branches in various districts and counties to query through touch terminals; Log in to the external service website of the local public security traffic management bureau, find the vehicle violation query section, enter the license plate number and engine number, and click to query; Call the inquiry hotline (area code + 114); Use the Traffic Management 12123 app (V2.8.1B437 for iOS 15+ or V2.8.1B274 for Android 12+) to query. For violations involving passenger vehicles other than road passenger transport vehicles carrying goods illegally, you can handle them through the Traffic Management 12123 app. After logging in, enter the violation handling process, complete the handling, and make the payment.
