New Passat air conditioning cleaning method is: 1. Remove the filter device, open the doors and windows, and set the cold air to high gear; 2. Spray the air conditioning cleaner into the air intake, while closing the air conditioning vents to prevent the cleaner from flowing out during operation; 3. Start the car and let the cleaner circulate in the air conditioning system to ensure that the cleaner circulates to the air conditioning system. The New Passat is a mid-size sedan designed by Volkswagen AG in Germany, with body dimensions of 4933mm in length, 1836mm in width, and 1469mm in height, and a wheelbase of 2871mm. In terms of suspension, the New Passat's chassis suspension structure is front MacPherson and rear multi-link.
Every time I clean the air conditioning of my new Passat, I follow these steps: First, prepare a dedicated air conditioning cleaner and a new air filter. Park the car in a ventilated area, and after turning off the engine, locate the filter position behind the glove box on the passenger side. When removing the old filter, you will see a lot of dust and debris. Then, start the vehicle, set the air conditioning to the highest fan speed in external circulation mode, turn off the AC switch, and spray half a bottle of cleaning foam into the external air intake. Wait for ten minutes to let the foam dissolve the dirt, then spray the remaining cleaner. Continue blowing air for twenty minutes to expel the dirty water. Finally, replace the old filter with a new one and open the car windows for half an hour to ventilate and remove odors. Throughout the process, don’t skimp on buying low-quality cleaners, as they can corrode the evaporator and cause more trouble.
My experience is that the air conditioning must be cleaned every 20,000 kilometers. The Passat's air conditioning system is particularly prone to mold buildup, especially during the transition between spring and summer. Specific steps: Purchase a cleaning kit with a long spray nozzle online, and pay attention to the direction of the clips when removing the filter. Apply the cleaner in three intervals of five minutes each to thoroughly dissolve the biofilm on the evaporator. When drying, remember to switch between cold and hot air for ten minutes each, and also use disinfectant spray on the vents. I just cleaned it last week, and now the cooling is noticeably faster. Most importantly, the musty smell in the car is finally gone, and my family no longer complains about dizziness during long drives.
Cleaning the air conditioning of a new Passat can be done in four steps: After disconnecting the power, remove the old filter and use an endoscope to check if the fan impeller is clean. Start the car, set it to maximum external air circulation, and inject specialized cleaning foam from the engine compartment air intake. While waiting for the foam to take effect, wipe the vent grilles. Installing a new activated carbon filter is particularly important as it can filter PM2.5. The entire process takes about half an hour, but be careful not to let the foam seep into the circuit board. After cleaning, it's recommended to drive with the windows open on the highway for a while to expel any residual moisture in the ducts.
