2014 328i xDrive M Sport, 25k miles, I have a vibration between 60-70 mph more prevalent at 65 mph and is stronger when accelerating. I have had the car for 2 months and is at dealer right now for the 3rd time. Picked it up 12/16, CPO so I've had no out of pocket costs but the dealer cannot solve this problem. Here's what was done so far ...

Replaced:

All 4 wheels
Tires are new 10/16
Front left wheel bearing
Front left strut

Vibration is still there and it's driving me nuts. Dealer says it's normal and that it's the engine / trans holding gear and that they tested a loaner with same specs (prob not m sport) and has same vibration. This is a secondary car I don't drive it everyday so they said could be flat spot on RFTs. I'm not taking that for an answer. Anyone else with similar problem? Suggestion? Driveshaft? Axles? Other wheel bearings? It's more evident under acceleration. Thanks!

Do a search. I'm almost positive that there is an older thread where someone had the same exact issue you are describing.

I've tried, new to the forum have not seen any posts with the same problem and or the fix.

If you have snow, there could be ice build up in the rims.

[14F30MSport]

No snow ... been happening at all times

Yea. I had salt build up inside of my rims that caused a vibration.

wheels were replaced but the tires were not? ask them to throw some new tires on (or swap out from a car in stock) to see and maybe road force balance. Runflats are evil in many ways

[14F30MSport]

Sent email to service advisor to see about tires and road force balancing. Thanks

[14F30MSport]

Road force balanced all wheels, one was way off they replaced that tire but vibration was still there. They swapped my driveshaft with another car on the lot and apparently that fixed it. They have new driveshaft on order so hopefully this is the true fix. Good thing I didn't settle with their original response that vibration was the engine holding gear nothing abnormal. Will post update.

It could be the 4wd system failed. Did you lowered your car? I had 325ix before and it was lowered. After lowered the car I could feel the vibration. They said it's from the shaft or the tie rods. They said that I'm not supposed to lowered the Xdrive BMW. Regular 325i is ok to be lowered

My car has vibration under acceleration too. Most probably the driveshaft since i've done 30+ Launch Control passes on drag strip. Ehh i'll just ride this one out until my lease ends

Good news! Glad they found the issue.

Was driveshaft in my e90 335xi, also equally painful resolution path since I kept saying driveshaft from day 1 and after a transfer case, front diff, front driveshaft later they finally got the main driveshaft and it was glass smooth.

[14F30MSport]

I am happy to say that this is finally FIXED! The driveshaft cleared it all up and now I can truly enjoy the car. Just purchased on 12/2/16 and it's been in the shop 3 times. Thanks for all the posts! First project upgrade stock halogens to LEDs. Picked up spektrum and weisslicht bulbs from bimmian for highs / lows / daytime and parking. I wish this has the adaptive leds but not the end of the world. Thanks again
