What is the solution for the gurgling sound in the Audi A6L?
2 Answers
Audi A6L's gurgling sound is emitted by the dual-clutch transmission, which is a normal phenomenon. One set of the dual-clutch transmission's clutches is used to control the odd-numbered gears, while the other set controls the even-numbered gears, improving the car's shifting speed and transmission efficiency. Taking the Audi A6L 2021 40TFSI Luxury Elegance model as an example: it is a mid-to-large-sized car with a length, width, and height of 5038mm, 1886mm, and 1475mm respectively, and a wheelbase of 3024mm. It is equipped with a 2.0T turbocharged engine, delivering a maximum power of 140kw and a maximum torque of 320nm, with the maximum power speed ranging from 4200 to 6000rpm per minute, matched with a 7-speed dual-clutch transmission.
I also encountered a similar gurgling sound issue when driving my Audi A6L, especially noticeable during low-speed turns or going over speed bumps, as if something is rubbing. I found that the source is mostly due to excessive gaps caused by aging shock absorbers or bushings in the suspension system, with the sound coming from the wheel area. The solution is to take it to a professional repair shop and have the suspension components inspected using a lift, then replace the worn rubber parts or the entire shock absorber assembly. After I replaced mine last time, the sound disappeared immediately, costing around a few hundred yuan. Don’t try to fix it yourself—Audi’s chassis is precise and easily damaged. Regular maintenance of suspension points, such as lubricating the rubber bushings every six months, can effectively prevent this issue. Ignoring it will worsen the noise and affect driving safety, making turns and lane changes unstable. Additionally, check the tire balance; poor wheel balance can also cause strange noises. A wheel balance costs just a few dozen yuan and is a simple, worry-free fix.
