So, since Christmas, I have noticed a whine when I accelerate in 4th-6th gear. I first noticed it on my trip from PA to FL over Christmas, while I was on the highway. It's loud enough that it makes me worried that the turbo or something is going. It usually happens when I'm doing highway driving, or prolonged/harder driving. I don't usually hear it while doing my 40-minute commute to work. It's worst when under about 3/4 throttle, and is not noticeable under half or less, or full throttle. I don't have any videos, but I don't think it would be loud enough to pick up on video anyway. Maybe the whine is normal, and I'm just being paranoid, but it would be nice if someone might have an idea of what could be wrong, if anything is. Any input is much appreciated!
