The urea filter generally needs to be replaced every 50,000 to 60,000 kilometers. All vehicles with diesel engines require urea. Diesel engine vehicles have a urea nozzle in the exhaust pipe, which sprays a urea aqueous solution to purify the exhaust gas. Methods for cleaning the urea nozzle: 1. A small ultrasonic cleaner can be used for cleaning, with each cleaning session lasting no less than 15 minutes. During cleaning, functional tests can be performed to drive the nozzle, which improves the cleaning effect. 2. It can also be cleaned by soaking in warm water, with each session lasting no less than 15 minutes. Be careful not to immerse the plug in water.

Why does the Jetta VS5 require 95-octane gasoline?

The reason the Jetta VS5 uses 95-octane gasoline is to ensure stable engine operation and optimal combustion conditions with higher-octane fuel. Avoid overfilling the tank: Overfilling can easily block the fuel tank vent. Once the vent is blocked, the internal pressure of the tank will drop below normal levels, leading to poor fuel supply or even fuel cutoff. Overfilling also increases the vehicle's weight, thereby increasing fuel consumption. Additionally, gasoline can deteriorate, posing potential safety hazards. Refuel before the warning light appears: While driving, always monitor the fuel gauge. When the indicator shows only a quarter of the tank remaining, it's time to refuel. If the tank remains empty for too long, the temperature difference between inside and outside can cause condensation inside the tank. This moisture can corrode the tank, affect fuel quality, and increase the engine's workload.
