The reasons why the transmission makes a noise when shifting gears: 1. The transmission housing is damaged, and the transmission housing and bearing seat holes are worn and deformed over time; 2. Due to the fracture of individual gear surfaces, causing impact during meshing; 3. Improper assembly of the transmission, improper replacement of gears or needle bearings and bushings in a certain gear of the transmission, abnormal assembly clearance, resulting in poor gear meshing and abnormal noise during transmission in that gear; 4. Poor technical condition of the external transmission system (clutch, drive shaft), which causes impact and vibration during use, leading to transmission resonance and resonance noise; 5. Noise caused by other factors in the transmission, such as the number of simultaneously working gears, rotation speed, working specifications, load, insufficient lubricating oil, and many other factors.

What is the standard for Audi's oil consumption?

Audi's standard for oil consumption is between 5,000 to 10,000 kilometers. Factors affecting car oil consumption: Wear of piston rings, weakened or broken piston ring elasticity, misalignment of piston rings (where several piston ring gaps form a straight line) can cause poor sealing, allowing some oil to enter the combustion chamber and burn. Aging or damaged valve stem seals can also allow oil to enter the combustion chamber, especially if the intake valve stem seals are aged or damaged, making it easier for oil to enter the combustion chamber. Methods to reduce car oil consumption: Use high-quality fuel; clean carbon deposits, which can be done using cleaning lubricants; regularly inspect and replace the air filter as needed; if too much oil is added, use a syringe connected to a tube inserted into the dipstick to extract excess oil, or visit a repair shop or 4S store to use professional equipment for extraction. Pay attention to the amount of oil added, ensuring the oil level is between the highest and lowest marks on the dipstick.
