How often should small cars undergo annual inspection?

What does it mean when the ECU light is on in a Baojun 730 AGS?

If the warning light has not come on, there is no problem. When the car is running, if certain sensor parameters exceed standard values, the ECU will recognize it as a fault, and the corresponding fault code will be stored. If it is a qualitative fault, the decoder cannot erase it. Introduction to the Car ECU: ECU (Electronic Control Unit), also known as the "vehicle computer" or "on-board computer," is essentially a specialized microcomputer controller for automobiles. Just as humans have a brain, computers have a CPU, and cars have an ECU. Scope of the ECU: Initially, the ECU was used to control engine ignition and fuel injection, so in a narrow sense, it is the engine control unit. As automotive electronic systems evolved, more functions were added, such as controlling the chassis (ESP, ABS, ASR) and controlling the transmission (TCU for automatic transmissions). Therefore, these control units are now collectively referred to as electronic control units, or ECUs in a broader sense.

Does a car registered in June 2012 require an annual inspection in 2021?

2021 does not require an annual inspection, but 2022 does. The annual inspection must be completed before June 2022 for the vehicle to be legally driven. The inspection is an on-site inspection and must be conducted at the vehicle management office or the traffic management department of the public security authority. Required documents include the compulsory traffic insurance policy and the vehicle registration certificate. Details are as follows: 1. Inspection cycle: The latest for an annual inspection is three cycles. If the vehicle is not inspected for three consecutive cycles, it will be forcibly scrapped by the vehicle management office or the traffic management department of the public security authority. Vehicles that are forcibly scrapped cannot be driven on the road, and doing so is illegal. 2. Inspection methods: There are two methods for vehicle annual inspection. The first method is through the mobile app "Traffic Management 12123," which is only applicable to vehicles exempt from on-site inspection and must be completed within the inspection period. The second method is on-site inspection, which can be done at the local vehicle management office or vehicle inspection station.

How much engine oil should be added to a Volkswagen 1.4T engine?

Generally, adding about 3.8 liters is sufficient. The specific amount can be checked using the oil dipstick. It is best to use fully synthetic oil. Car buyers must pay special attention not to add too much oil during the process. When the oil level is higher or lower than the acceptable operating range indicated on the dipstick, it can be harmful to the engine. Choosing the right engine oil: The selection of engine oil should be based on the engine's requirements. Do not use high-grade oil in a low-performance engine, nor use low-grade oil in a high-performance engine. Choose oil that matches the engine's specifications. Multi-grade oil is recommended, as it offers advantages such as fuel efficiency, long service life, and high performance. Precautions when adding engine oil: The oil level should be slightly below the mark on the dipstick. Engine oil is extremely important for the engine's operation, as it is responsible for both lubrication and heat dissipation. Therefore, the engine should never run low on oil at any time. However, adding excessive oil can have adverse consequences.

Where are the three pipes of the Haval H5 diesel filter located?

Haval H5 diesel filter's three pipes are located when lifting the car or going underneath. The coarse filter is near the fuel tank. The fine filter is on the lower left side of the engine. Introduction to diesel filters: The diesel filter is one of the important components ensuring the quality of diesel entering the engine. Diesel filters are mainly divided into two types: spin-on and replaceable. Function of diesel filters: High-quality diesel filters can effectively block the fine dust and moisture carried in diesel, and can greatly extend the service life of fuel injection pumps, diesel nozzles, and other filtering components. Large and small oil droplets, with the larger ones easily separated by the oil-gas separator, while the smaller ones (suspended oil particles) must be filtered through the micron-level glass fiber layer of the oil-gas separation filter. When the diameter and thickness of the glass fiber are correctly selected, the filter material can intercept, diffuse, and aggregate the oil mist in the gas, achieving the best effect.

Is the fee for license replacement on 12123 paid upon delivery?

The postage for license replacement is paid upon delivery. Below is relevant information about driver's licenses: 1. Annual review requirements: No annual review is required within the 6-year validity period of the driver's license. Drivers should apply for license replacement at the traffic police branch under their jurisdiction within 90 days before the expiration date. Holders of A, B, N, and P licenses no longer need to undergo annual reviews during the validity period, but within 15 days of the original annual review deadline, they should go to the vehicle management section of the traffic police branch under their jurisdiction to obtain the "Motor Vehicle Driver's License Application Form," fill it out as required, attach a photo, undergo a medical examination at a designated hospital, and then submit the form back to the vehicle management section for computer confirmation. 2. Medical examination: Drivers aged 60 and above, regardless of the type of license they hold, must go to the vehicle management section of the traffic police branch under their jurisdiction during the original annual review period to obtain the "Motor Vehicle Driver's License Application Form," undergo a medical examination at a designated hospital, and then submit the form back to the vehicle management section for computer confirmation.

How to Solve the Problem of Frozen Car Evaporator and No Airflow?

The reasons for the car evaporator freezing are as follows: 1. Reason one: The expansion valve's adjustment is too small, resulting in excessively low low-pressure. 2. Reason two: Insufficient refrigerant in the system, causing the evaporation pressure to be too low. 3. Reason three: The internal circulation filter is clogged. 4. Reason four: The temperature control or temperature sensor is malfunctioning, and the compressor does not shut off. 5. Reason five: The energy control valve or pressure regulating valve of the variable displacement compressor fails, causing the compressor to operate at full capacity continuously, leading to excessively low low-pressure and evaporator frosting. Solutions for the frozen evaporator are as follows: 1. Check the temperature control sensing bulb: Ensure it is in the correct position. 2. Check the temperature control adjustment: Adjust it slightly smaller if possible; if not adjustable, replace the temperature control. 3. Check the air conditioning computer control: Determine if there is a fault. 4. Check the evaporator for freezing: Besides the compressor not shutting off, also inspect if the evaporator fan's inlet and outlet dampers are blocked. 5. Check the fan speed setting: If it is set too low, increase it to enhance the circulation of heat, which will naturally improve performance in hot weather. 6. Check the temperature damper system control: It is operated by a servo motor. If the damper system malfunctions and air cannot circulate, the evaporator will freeze.
