Reasons for Excessive Carbon Monoxide in Vehicle Exhaust

Excessive carbon monoxide in the exhaust may be caused by incomplete combustion of gasoline in the engine. The main reasons and solutions are as follows: Main reasons: Spark plug failure, poor ignition, excessive cylinder wall clearance, uncalibrated valve timing, failed catalytic converter, poor fuel injector atomization, etc. Carbon buildup inside the engine fuel system, or a clogged/dirty catalytic converter that has lost its ability to convert carbon monoxide. Solutions: Remove engine carbon deposits, or clean/replace the catalytic converter. The correct solution should be determined based on accurate diagnosis of the excessive emission causes through steady-state exhaust gas test data.

How long does maintenance at a 4S store take?

The specific time required for car maintenance at a 4S store depends on the actual situation. Generally, if you go for maintenance on a weekday, it can be completed within two hours. However, if you go on weekends or holidays, it may take more than two hours. When the car owner arrives at the 4S store, a dedicated maintenance receptionist will be responsible for the reception. After the reception, the service advisor will discuss the maintenance costs with the car owner. Once the required items and costs are confirmed, a maintenance technician will drive the car into the work bay. This process usually takes about 20 minutes. After the car enters the work bay, the maintenance technician begins the maintenance. First, they lay out the fender pads and the five-piece set inside the car, then wait for the warehouse to deliver the materials. This is followed by a routine oil change and a safety inspection of the car's condition. If safety issues are identified, the maintenance technician will go to the warehouse to prepare a quote, which is then handed to the service advisor. The service advisor will communicate with the customer to decide whether to proceed with the repairs. If repairs are needed, the waiting time will depend on the specific items to be addressed. If no safety hazards are found, the above process takes about an hour. After the maintenance is completed, the maintenance technician moves the car to the car beauty center for washing. Once the car is washed, the maintenance technician or the quality inspection department will inspect the car. After the inspection, the maintenance technician moves the car to the finished parking space, and the service advisor handles the payment. This process takes about 20 minutes. In summary, car maintenance generally takes about two hours.

What to Do If You Lose Your ETC Card?

ETC card replacement method: The vehicle owner should bring their ID card, the original and a copy of the vehicle registration certificate to the bank counter to handle the card change or replacement. The installation process for the ETC device is as follows: Upon receiving the device, first check if the ETC card and the electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU. A red light will briefly illuminate, and the OLED screen will display "Tag Invalid" or "Please Insert Card," indicating the device is functioning normally. Clean the front windshield to ensure the surface is smooth, clean, and dry. Then peel off the adhesive backing of the OBU and stick it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front facing the driver and the back facing the windshield, ensuring the chip is inserted into the OBU device. ETC device activation method: Insert and remove the ETC card twice consecutively until the electronic tag screen displays "Bluetooth On." If "Tag Invalid" appears when inserting and removing the card twice without the electronic tag attached, this is normal and does not affect activation. Alternatively, press the button on the top of the electronic tag to enable Bluetooth directly. Turn on your phone's Bluetooth and open the corresponding mobile app (usually with a download QR code on the electronic tag), then enter the device activation interface. Click "Device Connection" and wait patiently for the "Connection Successful" prompt. After a successful connection, upload a photo of the front of your vehicle to complete the activation.

What is the size of a 400-12 tire?

400 represents the tire section width of 400mm, and the following 12 indicates the rim diameter of 12 inches. Tire size specification example (taking 195/55R15 as an example): The international standard tire code represents the section height and aspect ratio percentage in millimeters, followed by the tire type code, rim diameter (inches), load index (allowable load mass code), and allowable vehicle speed code. For example, 175/70R1477H, 175 represents the tire width of 175MM, 70 indicates the tire section aspect ratio is 70%, meaning the section height is 70% of the width, the rim diameter is 14 inches, the load index is 77, and the allowable vehicle speed is grade H. Notes for replacing car tires: When selecting tires, the specifications of the tires should be the same as the previous ones and must match the other tire on the same axle, such as speed rating, load index, tread pattern, brand, size, etc., to ensure safe driving. The valve stem should also be replaced because after changing the tire, the aging cycle of the new tire and the valve stem may differ. During the new tire's cycle, the valve stem might develop issues, which are not easily noticeable, so it's best to replace the valve stem when changing the tire. Installation direction and inflation: If using the original equipment tire, follow the manufacturer's installation requirements. For non-original tires, the side with the production date usually faces outward. If it's a directional tire, align the arrow on the wheel with the car's forward direction during installation. During inflation, you can fill the tire to the maximum allowable pressure and then reduce it to the manufacturer's specified standard pressure.

Where is the rearview mirror folding button for the Volkswagen T-Roc?

The folding button for the Volkswagen T-Roc's rearview mirror is located on the door armrest. Here are some precautions for using the rearview mirror: 1. Before adjusting the left and right rearview mirrors, rotate the knob to align with the left or right rearview mirror button, then you can adjust the mirror up, down, left, or right. Aligning the knob to the left adjusts the left mirror; aligning it to the right adjusts the right mirror. 2. When no adjustment is needed, it is recommended to rotate the knob to "0" (neutral position) to effectively prevent accidental changes to other settings. The correct adjustment angles for the rearview mirrors are as follows: 1. Central rearview mirror: When the mirror is parallel to the horizon and the horizon is positioned at the center of the mirror (1/2 of the mirror height), the view is optimal. The mirror should slightly face the driver to ensure a clear view of vehicles directly behind. 2. Left rearview mirror: Adjust the horizon to the center (1/2) of the left rearview mirror, while ensuring that 1/4 of the car body is visible in the mirror. Pay attention to the proportion of the car body image in the mirror—if it occupies too much space, other vehicles may not be visible; if it occupies too little, you may not see vehicles closely following in the same lane. 3. Right rearview mirror: The adjustment method for the right rearview mirror differs slightly from the left one. First, adjust the horizon to occupy 2/3 of the right rearview mirror, while the car body occupies 1/4 of the mirror.
