What Causes the Buzzing Noise from the Rear Wheel of a Passat?
2 Answers
Passat rear wheel buzzing noise may be caused by tire or wheel bearing issues. Relevant introduction of Passat: 1. Interior: The interior adopts "Rhythmic Design", echoing the exterior. The large LCD display in the center console enhances its technological feel. The extensive use of soft materials, complemented by wood grain decorations, creates a comfortable and luxurious interior atmosphere. 2. Power: Equipped with EA211-1.4TSI turbocharged engine. The rated power reaches 110kW/5,000±200rpm, with maximum torque of 250Nm/(1,750-3,000)±200rpm.
As a long-time Passat owner, I've encountered similar issues. My rear wheels produced a low humming noise, especially noticeable during acceleration. After inspection, I found several common causes: Worn wheel bearings are the most likely culprit - damaged bearings often make this sound; Uneven tire wear could also be the reason if your tires have pressure imbalances or cracks; Brake system problems like warped rotors or rusted calipers may also cause it. Once while driving on the highway with this humming noise, I delayed repairs until the bearing completely failed and the wheel nearly came loose - extremely dangerous. I recommend first checking for wheel hub wobble by shaking the rear wheel manually; then visit a reliable repair shop for diagnostic equipment testing. Don't ignore it - delays lead to higher repair costs. Regular maintenance of tires and bearings can prevent such failures, as Passat's rear-drive structure is prone to this issue. Safety first - address it promptly.
