How to Check if the Catalytic Converter is Present

The safest method is to visit a reliable repair shop and use a lift to check whether the catalytic converter is still present under the chassis. Additionally, if the vehicle lacks a catalytic converter, the exhaust noise will be significantly louder, and the exhaust gas will emit a very unpleasant odor. Furthermore, if there is a popping sound from the front section of the exhaust pipe when accelerating, it indicates that the catalytic converter is missing.

What is the reason for the buzzing sound after the Tiguan is turned off?

When the engine of the Tiguan is still making noise after being turned off, it is actually the sound of the fan. The Tiguan is equipped with a turbocharged engine, and the fan continues to cool and rotate after the turbocharged vehicle is turned off, which is a normal phenomenon. More details are as follows: 1. When using a turbocharged engine model, it is important to note that after parking, do not immediately turn off the engine. During engine operation, some of the oil is supplied to lubricate the turbocharger rotor bearings and for cooling. 2. After a running engine is suddenly shut down, the oil pressure quickly drops to zero, and the high temperature from the turbocharger turbine section is transferred to the middle. The heat in the bearing support housing cannot be quickly dissipated, while the turbocharger rotor continues to rotate at high speed due to inertia. Therefore, if the engine is suddenly shut down while it is hot, it can cause the trapped oil in the turbocharger to overheat and damage the bearings. 3. After the engine has been running under heavy load for an extended period, it should idle for 3-5 minutes before shutting down to allow the turbocharger rotor speed to decrease. It is especially important to avoid suddenly shutting down the engine after revving it several times. After starting the engine, especially in winter, let it idle for a while to allow the lubricating oil to fully lubricate the bearings before the turbocharger rotor reaches high speed.

Why can't I bind my newly obtained driver's license to 12123?

Here are the reasons why new users cannot bind their newly obtained driver's license to 12123: 1. The mobile phone number filled in by the user does not match the one in use. 2. If the motor vehicle is deregistered or transferred to someone else, as long as it is under the user's name, it will be automatically bound on the Traffic Management 12123 platform. Below are the methods to unbind vehicles and driver's licenses from the Traffic Management 12123 platform: 1. Handle vehicle management procedures in a different location. After the platform is launched, procedures will be simplified, eliminating the need for paper materials such as business applications, and establishing a new working mechanism where application information is submitted online, materials are reviewed offline, and licenses and certificates are produced and delivered via mail. 2. Achieve online license and certificate processing. Through the platform, the public can easily handle various services anytime and anywhere, such as self-scheduling driver's license tests, pre-booking motor vehicle inspections, pre-selecting motor vehicle license plates, applying for replacement or renewal of licenses and certificates, and paying traffic violation fines. 3. Check violation information at any time. In terms of obtaining information, the public can query and dynamically track personal information such as motor vehicles, driver's licenses, and traffic violations through the platform. They can also promptly understand road conditions, dangerous road sections, road construction, and precautions for severe weather to better plan travel times and routes for safe travel.
