What does the Tiguan L leaf mean?
3 Answers
Tiguan L leaf refers to the in-car air quality, generally indicating particulate matter. Try smoking a cigarette inside the car, and it will soon turn red, with the number soaring to over 90. It seems to turn green when the value is below 30. Causes of in-car air pollution: In-car air pollution refers to the poor air quality inside the vehicle due to lack of ventilation, car interior decoration, and other reasons. The main sources of in-car air pollution come from the car body itself and decorative materials, among which toxic substances such as formaldehyde, xylene, and benzene have the most severe pollution consequences. Mainstream car models with carcinogenic in-car air: In September 2012, a "Healthy Car Testing Report" indicated that 11 mainstream car models might pose carcinogenic risks, with companies such as Changan, Chery, Shanghai General Motors, and Brilliance listed. The carcinogenic risk originates from the presence of carcinogens in the in-car air quality.
I've been driving the Volkswagen Tayron for several years and often encounter the issue of leaves clogging the air conditioning grille. It refers to the accumulation of fallen leaves at the vehicle's air intake, especially during autumn and winter when there are more falling leaves that can easily block it. Once clogged, the airflow from the AC becomes less smooth, the air inside the car worsens, and it may even cause the fan blades to jam. Once during a long-distance trip, I noticed the AC making strange noises, and upon checking, found the blades full of leaves. I had to use a small brush to clean them out. I recommend owners regularly inspect the front part of the engine bay to clear accumulated leaves and avoid long-term impacts on cooling efficiency. Additionally, leaves may accumulate near the wipers, and not cleaning them in time could lead to motor burnout. Overall, this isn't a design flaw of the vehicle but more of a routine maintenance matter. Developing a habit of cleaning is key—after all, the Tayron performs well, so don't let minor issues affect the driving experience.
I was discussing the 'leaves' topic of the Tayron in the car enthusiasts' group, and I think it might refer to the fan blade components of the air conditioning system. Because the air vents all have rotating blades to adjust the airflow direction, some people call them 'leaves' for convenience. In terms of design, the blade angles are adjustable, controlled via the central console to disperse the airflow. If the blades are deformed or dirty, it can affect the air volume and even cause noise. I've studied Volkswagen models, and the blade material is plastic, which is not easy to break but requires regular cleaning. Over time, if this step is neglected, dust and debris accumulate, reducing the air volume by half. Remember not to let children poke at the vent blades randomly, as they can easily break. From a safety perspective, good blade design enhances driving comfort. It's recommended to check the air conditioning system, including the blade area, every six months to ensure smooth ventilation.
