What to Do When ETC Visa Fails?

ETC displaying label detachment means the device is currently unavailable and needs to be reinstalled and reactivated at the original processing point or any highway ETC service center. The ETC installation process is as follows: Upon receiving the device, first check if the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU, the red light will briefly illuminate, and the OLED screen will display "Visa Invalid" or "Please Insert Card," indicating the device is functioning normally. Clean the front windshield, ensuring the glass surface is smooth, clean, and dry. Then peel off the adhesive backing of the OBU and stick it to the installation position, pressing firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front side facing the driver and the back side facing the windshield, ensuring the chip is inserted into the OBU device. ETC 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 twice without attaching the electronic tag, this is normal and does not affect activation. Alternatively, press the button on top of the electronic tag to enable Bluetooth directly. Turn on your phone's Bluetooth and open the corresponding mobile app (usually a download QR code is provided on the electronic tag), then enter the device activation interface. Click on device connection and wait patiently for the "Connection Successful" prompt. Once connected, upload a photo of the vehicle's front to complete activation.

What are the reasons why Volkswagen's start-stop function is not working?

There are generally the following reasons why Volkswagen's start-stop function suddenly stops working: accidentally pressing the auto start-stop button, the system not recognizing the action, not meeting the start conditions, and a malfunction in the auto start-stop system. Accidentally pressing the auto start-stop button: Generally, vehicles equipped with the auto start-stop function have the system enabled by default. If it suddenly stops working, it might be because the auto start-stop button was accidentally pressed, causing the system to turn off. Check whether the system has been turned off. The system not recognizing the action: For manual transmission cars, the conditions for enabling the auto start-stop function are a bit more complex. When parking, the system will only activate after recognizing three actions: "shifting to neutral, pulling the handbrake, and releasing the clutch." Not meeting the start conditions: Different models from various brands have different designs for the auto start-stop system. Taking the auto start-stop system of the new Passat as an example, it must meet certain conditions. Specifically, the seatbelt must be fastened, the left front door must be closed, and the engine must be running. So, check the user manual for any precautions. Auto start-stop malfunction: An auto start-stop malfunction could be due to wiring issues or other reasons causing the system to fail. In this case, it's best to take the car to a 4S shop for inspection and repair.

How to Eliminate the Tire Pressure Monitoring Alarm?

Tire pressure alarm indicates that the pressure in the four wheels is uneven, possibly due to a tire being underinflated or punctured. Ensure the tire is properly inflated. If there is no puncture, the alarm may automatically reset after driving for a while or can be manually reset via a button. Tire Pressure Monitoring: Tire pressure monitoring involves real-time automatic monitoring of tire pressure during vehicle operation, alerting the driver to leaks or low pressure to ensure driving safety. Direct Tire Pressure Monitoring: Direct tire pressure monitoring systems use pressure sensors installed in each tire to directly measure tire pressure. The pressure data is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure for each tire. The system automatically alerts the driver if the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between tires, the system monitors tire pressure. Indirect tire pressure monitoring systems essentially rely on calculating the rolling radius of tires to monitor pressure. Tire Pressure Monitoring System (TPMS) Overview: This system combines the advantages of both direct and indirect systems. It equips direct sensors in two diagonally opposite tires and includes a four-wheel indirect system. Compared to a full direct system, this hybrid approach reduces costs and overcomes the limitation of indirect systems, which cannot detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires as effectively as a full direct system.

What are the engine sensors?

Engine sensors include air flow sensor, throttle position sensor, accelerator pedal position sensor, intake air temperature sensor, coolant temperature sensor, camshaft position sensor, etc. Engine sensors are an indispensable part of automobiles. An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. The engine can be used as a power generation device or refer to the entire machine including the power device (such as gasoline engines, aircraft engines).

How to Use the Electronic Parking Brake in an Automatic Transmission Car

Automatic transmission cars use the electronic parking brake as follows: 1. Press the electronic parking brake to release braking; 2. Lift the electronic parking brake to engage braking. The electronic parking brake, also known as the electronic parking brake system, integrates temporary braking during driving with long-term braking after parking, achieving parking braking through electronic control. Electronic parking brake systems are categorized into: 1. Cable-type electronic parking brake system: retains the cable of the traditional mechanical parking brake system; 2. Caliper-integrated electronic parking brake system: consists of an electronic button and motor assembly.

How to resolve ESC malfunction in Volkswagen Golf?

Volkswagen Golf ESC malfunction requires taking the car to a repair shop for maintenance and resolution. Reasons for ESC malfunction causing failure to start: ABS pump failure or throttle body contamination; speed sensor malfunction or contamination leading to erroneous signal output; malfunction can result in reduced control performance during sharp turns and sudden braking. Function of ESC: ESC significantly enhances vehicle control safety and driving convenience. In emergency situations such as sharp turns, sudden acceleration, and emergency braking, the vehicle can quickly detect and implement appropriate braking measures to maintain stability.
