Applying undercoating to a new car is beneficial. Its primary function is to enhance the corrosion and rust resistance of the car's chassis metal. Functions of undercoating: The main purpose of undercoating is to protect the chassis from direct damage caused by flying gravel and uneven road surfaces. Its unique integrated features of sound insulation, impact resistance, and rust prevention can indeed save car owners significant costs in later chassis maintenance. Method for applying undercoating to the Volkswagen Tayron: After lifting and securing the vehicle, use a rust remover to spray any rusty areas on the chassis, then wipe dry. First, apply the first bottle of undercoating evenly on the surface. One bottle is definitely not enough; apply additional bottles as needed. After completing the application, wait for the vehicle to dry.

As an average car owner, I think getting undercoating for a new car is totally worth it. If you live in areas with heavy rain or snow, or in coastal cities, undercoating can effectively protect the chassis from corrosion and prevent rust or pitting. Spending a bit on undercoating when the car is new means the chassis stays shiny for years and saves you a lot of repair headaches. My previous car didn’t have undercoating when new, and after just two or three years, it started rusting and cracking—repairs cost me over ten thousand, way more than the cost of undercoating. Nowadays, undercoating materials have improved—they’re eco-friendly, durable, and installation is hassle-free, taking just half an hour at a professional shop. The added weight barely affects fuel efficiency. Just make sure to pick a reputable shop to avoid minor issues like uneven coating trapping moisture. Overall, spending around two thousand for peace of mind and long-term protection that extends your car’s lifespan is definitely worth it!

The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. This means that in the national standard, the significance of vehicle width data is to ensure enough space during overtaking, preventing accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, the national regulation stipulates that the total width of a vehicle must not exceed 2.5m to meet the usage requirements of public roads.

Does OBD Tire Pressure Monitoring Cause Damage to the Car?

OBD tire pressure monitoring does not cause damage to the car. OBD tire pressure monitoring detects tire pressure indirectly. During vehicle operation, OBD continuously monitors the working conditions of the engine's electronic control system and other functional modules of the vehicle. If any abnormal conditions are detected, it determines specific faults based on specific algorithms and stores them as diagnostic trouble codes in the system's memory. OBD, which stands for On-Board Diagnostics in Chinese, provides useful information after self-diagnosis that can assist in vehicle maintenance and repair. Technicians can use the vehicle's original equipment to read the fault codes, enabling quick fault localization for vehicle repairs and reducing the time required for manual diagnosis.
