Where is the Audi tire pressure reset button located?

Audi's tire pressure reset button is located in the circular button on the center of the dashboard. The specific method is to press the CAR menu button, then rotate the central circular button to set the reset, select tire pressure reset, and the tire pressure monitoring system will store the current normal tire pressure data, automatically clear the original data. Finally, the warning light on the dashboard will turn off, indicating the tire pressure reset is complete. Tire pressure reset is an operation performed on the tire pressure monitoring system to reset it after resolving tire pressure faults. Abnormal tire pressure warning lights generally occur due to the following 3 reasons: Abnormal tire pressure: Typically, the system will alert when pressure is below 1.8bar or above 3.0bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure reset is not performed promptly, the tire pressure monitoring system will still record the original data, causing the tire pressure warning light to illuminate. Simply performing a tire pressure reset will resolve this. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is directly installed inside the tire and connected to the tire inflation valve. If the tire is impacted while driving, damaging the sensor, it can also trigger the tire pressure warning light. For sensor damage issues, the only solution is to replace it with a new component.

Does the Geely Panda have a catalytic converter?

Geely Panda is equipped with a catalytic converter, which is located in the first drum section of the vehicle's exhaust manifold, resembling the shape of a canteen. Composition of the catalytic converter: The catalytic converter generally consists of four parts: the shell, damping layer, substrate, and catalyst coating. Shell: Made of stainless steel to prevent oxidation scale from falling off, which could clog the substrate. Damping layer: Composed of padding or wire mesh, it serves to seal, insulate, and secure the substrate. To protect the substrate from damage due to vibration, thermal deformation, etc., the padding is made of expanded mica and aluminum silicate fibers, bonded together with adhesive. Substrate: Made of honeycomb ceramic material, though many also use metal (including stainless steel) materials. Catalyst: Composed of precious metals such as platinum, rhodium, and palladium, sprayed onto the substrate to form the purifying agent. Lifespan of the catalytic converter: The lifespan of a catalytic converter is typically between 80,000 to 100,000 kilometers. The exact lifespan depends on the vehicle's usage conditions, and it is also related to the quality of fuel used and the driving environment.
