Where is the air pump located in the Mercedes-Benz GL450?

[Pluto]

The air pump in the Mercedes-Benz GL450 is located behind the right front bumper. It can be seen after removing the protective cover. Reasons why the Mercedes air pump fails to inflate: 1. The internal spring plate in the air pump softens over time. When the air reservoir reaches a certain pressure, the softened spring plate cannot rebound due to the counter pressure from the air reservoir. 2. Blockage in the air pump tube. This can be easily checked by disconnecting the air pump tube from the dryer and starting the pump. If black smoke-like substances come out of the tube, it indicates a blockage. 3. Leakage in the tube. Air escapes while pumping. 4. The water tank switch fails to close, causing air pressure to leak from the water tank. Solutions for the air pump failing to inflate: 1. If the air pump inflates slowly, it may be due to insufficient power. Consider replacing it with a higher-power model. 2. If the air pump cannot inflate, it might be because the tire pressure is too high. Regularly check tire pressure to avoid affecting normal use. 3. All valves in the air pump require regular maintenance to extend their service life. 4. The wiring of the air pump is thin. Avoid squeezing the wires during storage to prevent damage to the device.
