How to Solve the Transmission Noise Issue in Volkswagen CC?
2 Answers
Solutions for the transmission noise issue in Volkswagen CC are as follows: 1. Body noise This problem is usually caused by insufficient body stiffness, leading to deformation of the vehicle during driving, friction or shaking between the door and the frame, or friction between steel plates due to welding failures in some areas. Applying adhesive tape on the doors and windows or placing rubber pads in the friction areas may reduce or eliminate the noise, but these are temporary fixes rather than permanent solutions. 2. Engine compartment noise There are various possibilities for noise in this area. A high-pitched belt squeal is generally caused by belt slippage. If there is a dry friction sound of metal parts outside the engine during operation, it usually indicates damage to the bearings of the generator, water pump, or power steering pump. It is important to note that if the noise originates from inside the engine, most car owners cannot resolve it themselves, and it is best to send the vehicle to a professional repair shop for inspection and repair.
My Volkswagen CC's transmission is making strange noises, and I suspect it's due to worn bearings or gears. Such issues are common with Volkswagen's dry dual-clutch transmissions. Check the lubricant level yourself by looking at the dipstick to see if the oil is dark or sticky. If it's deteriorated, replace it immediately. I recommend changing the transmission oil regularly during maintenance to extend its lifespan. Don't attempt to fix it yourself; instead, seek a professional diagnosis from a 4S shop. They can scan for fault codes with specialized equipment, which is more reliable. Pay attention to the location of the noise while driving—for example, if it occurs during gear shifts, the clutch might be faulty. Addressing the issue early can avoid costly major repairs, saving you money and peace of mind. Also, don’t forget to check for loose transmission mounts, which can cause vibration and noise—another common cause. Proper overall maintenance can reduce problems and extend the vehicle's lifespan.
