What Causes the Transmission Noise in the 2021 Sagitar?
2 Answers
The causes of transmission noise in the 2021 Sagitar are as follows: 1. Use of inferior transmission oil: Inferior transmission oil has poor temperature resistance, is prone to oxidation, and can produce sludge and residue, which can clog the filter screen and oil passages, increasing friction between internal components of the automatic transmission and leading to abnormal noise in the vehicle. 2. Gear surface peeling or tooth breakage: If noise occurs in any gear, it is usually due to the rear bearing of the second shaft. Severely loose or damaged bearings should be repaired or replaced. If irregular noise occurs during vehicle acceleration, it may be caused by poor gear meshing inside the transmission.
As a veteran driver with over 20 years of experience, there are several common causes for transmission noise in the 2021 Sagitar. First is the transmission fluid issue - insufficient oil level or deteriorated fluid can increase internal component friction, causing abnormal sounds. Regular fluid changes are crucial. Second is mechanical wear, such as loose or damaged gears/bearings, which are prone to issues after prolonged high-speed operation. Additionally, improper installation like loose screws may also cause noises. The Volkswagen Sagitar uses a dual-clutch transmission (VW calls it DSG), and worn clutch plates or faulty shift modules can produce clicking sounds. Faulty sensors or electronic control malfunctions may also trigger abnormal noises. I must say, such issues are rare in new vehicles. If noises appear after 20,000 km, I recommend prompt inspection at a repair shop to prevent safety hazards. Maintaining smooth driving habits can extend transmission lifespan.
