2017 430i coupe with M package owner here, with 59k miles running factory spec staggered set up on stock 19 inch M wheels.

Anyone with a coupe notice any vibration or humming noise at highway speed? I am trying to figure out if the noise is a “characteristic” of the car or if there are other problems. Vibration/humming seem to be in the seats and center console area. Not noticeable in my steering wheel.

I have done the following:

Replaced front tires to match rear tires. Rear tires have 1500 miles on them so pretty much brand new. Tires are Yokohama advan A/S.
During the tire installation, tech noticed 3 bent rims. Rims were professionally repaired and rebalanced today.

There are few other options to diagnose the problem such as alignment check and replace wheel bearings. Wheel bearings are last on my list because I don’t know if my extended warranty will cover the claim since it’s only been 500 miles since I purchased the car.

Any thoughts?

hmm are they run flat tires? i had humming and ended up replacing to non run flats & don't have the issue anymore

All tires are the same Yokohamas, non run flat tires. Shops can’t seem to figure out what’s wrong.

I’ve been replying to that post as well

If anyone cares, here’s my update:

Complained to BMW dealer and front driver wheel bearing was replaced. Tech confirmed no more noise. He is wrong. I pushed to 90 mph and humming/wop wop wop is still there.

Took car to discount tires. No issues with tires but had them do road force balancing. Found one wheel with 32 lbs of road force and threshold is 35 lbs. Got that wheel down to 14 lbs. Wop wop wop noise is still there at 90 mph. Feels like it got little better but honestly no idea.

Got my car aligned right afterwards. Decent amount of adjustments were made and tech test drove and confirmed the noise. He said no worries it’s just tire noise. I confirmed noise is still there at 90 mph.

My car is staggered set up, 225/19 front and 255/19 rear. All Yokohama advan sport a/s, front tires are brand new and rear tires are 1000 miles old.

I spun the rear wheels with my hands while it was lifted. Saw the driveshaft move with some clicking sound while it’s spinning. Doesn’t sound abnormal. But maybe at high speed that clicking sound is amplified. I really don’t fucking know anymore.

Am I paranoid, too anal, or flat out wrong about the wop wop wop sound that I hear at 90 mph?

Help

I think there was one person who had the driveshaft replaced and fixed the problem.

Thanks. I read through the novel of that thread. I’m glad I’m not alone but misery loves company. Got some new ideas to try so thanks for the suggestions!

Dealer quoted $1800 f32 driveshaft for manual tranny. And not available in US so shipped from Germany in 20 days. Idk what the labor would be. Found alternatives online but this job is not something I feel comfortable doing.
