I had a similar vibration that drove me insane. First time dealer blamed it on tires. After replacing those they blamed it on bent wheels. Had wheels inspected and there were no bends. They ended up replacing my drive shaft and car is smooth as silk again.

Thank you for that update, Did the warranty cover it?

What I can say is that as you accumulate miles the issue seems to diminish. I have no idea why and neither does BMW. |

BUMP !
I have a brand new F30 ( about a month old ) and its exhibiting the EXACT same behaviour as per that video. Can happen at various speeds and on different surfaces.
I will take it in for wheel balancing today and report back. I noticed that some say the vibe will disappear after some miles - did anyone have this experience and after how many miles ? |

F34 320i GT built in April 2018 behave EXACT the same. I discovered the abnormal vibration recently and could not get an explanation from my dealer.
P.S. Wheel balance are done and tires are in good condition. |

Some say the steering column was the issue. Have the dealer check it out.

My 2 cents. 4 weeks ago I bought my first BMW, a 2014-10 320d EDE automatic. I test drove the car twice because of the horror stories regarding the steering wheel vibration. The car drove flawlessly, the only thing that caught my eye was that the tire pressure on left rear was a bit low but everything else was perfect. So I bought the car. Before delivery they replaced the brakes, the fluids and filters. After 7 days I picked up the car and drove home. On my way home you can already guess it, the steering wheel vibrated from left to right between 75 km/h and 90 km/h... The next day I drove back, they eventually rebalanced the tires twice in 1 week time but it didnt help. I went to another garage for a second opinion and they said that the tires were perfectly balanced. So 4 weeks of headaches, reading forums, watching YouTube clips but I couldn't find a real solution. Two days ago by just a coincidence I looked at the tire pressure and it was pretty high, it was on 2,7 bar (39,2 psi) on the front and back. I remembered when I test drove the car it was around 2,1/2,2 bar. So I lowered the front tot 2,2 (31,9 psi) and the rears to 2,4 (34,8 psi). Went on the highway and the shimmy steering wheel had disappeared... So is this pure luck or... The tires are Pirelli Cinturato's runflats.

Tire pressure has a lot to do with ride quality and steering wheel activity. The factory recommendations are 32 psi front and 38 psi rear cold. However , i always put 33 psi front and 36 psi rears, and i have never felt any abnormal vibrations |

A road force balance will likely show the error and whether the tire can be remounted and brought within acceptable tolerances. Remember even bent rims can be 'balanced', but the wheel doesn't run true and can vibrate once carrying load. |

Wheel bends are very common on BMWs in the Northeast, my Indy says they see at least one good bend on every car that comes in if it has gone through a winter. I do believe there is some underlying driveline vibration depending on RPM and throttle application at high speeds. On track where I am accelerating at wide open throttle I can't detect it, but when mildly rolling on the throttle beyond 90mph I can. Not bad enough to concern me, it may be pressure related.

Hello guys, I'm having same problems as listed above. My car is BMW F31 320i 2016 and steering wheel is vibrating in speed 70-90kmh (40-60 mph). More noticeable after car have stand over night. While braking vibration feels about the same. Wheels and tires are aftermarket 19 inch and have been checked and balanced several times. I have tested low and high tire pressures makes no difference. Is there problem with brakes or do I have some bushing worn out? Car is 100 000 km (60 000 miles) driven.

Any news?
My case - vibrations at 90 km/h. - new disc brakes - new disc pads - wheels swapped to front/rear and winter/summer - wheels balanced - disk brakes deviaton <0.2 - hub deviation <0.1 - new top/bottom wishbones The issue comes after night, and only at 90km/h. When i drive some time its going to be fine. Its only at the first kilometers of trip and only on flat straight road. No shimming during braking. The thing that cause it smaller - i removed the wheels, loosed the disc brake screw, then tighten the disc brake to hub by 5 screws and 140Nm, then i screw the small rim screw, but not very tight, then removed wheel screws, put the wheel, screw the wheel on axis and 140Nm. Now its minimal, but still is. Any ideas? Last edited by Kyokushin; 03-21-2024 at 08:45 AM.. |

I see. I had a new 2014 328i that had the shimmy issue at about 40MPH. That car had Pirelli P7 runflats. If I remember correctly the problem slowly went away as the tires wore. I now have a 2017 330i. When the car was new I had the same shimmy problem with Continental ContiSportContact SSR tires. Those tires were so noisy that I replaced them at 10k miles with Bridgestone Driveguards. The shimmy went away immediately. I have a feeling that the shimmy is due to manufacturing variations in runflat tires. If your tires are nearing their wear limit, you may want to try the Driveguards or possibly Michelin MXM ZP tires. Of course going with non-runflats is also an option.

In last weeks i have done several tests, and my findings to reduce the shimmy are:
- wheels need to be perfectly balanced. hunter is good option to go. - disc brakes - need to be perfectly flat. Even less than 0.02mm. - it is connected with the road surface - it is connected with the tire pressure - i hink 'slightly more', 1 bar, is slightly reducing shimmy - after few kilometers it may gone - the torque for wheels need to be equal 140Nm - the way how you install the disc brake on the hub HAVE MATTER. You need to find a sweet spot before you screw the rotor to hub, screw it by wheel screws, then tighten the small screw - release of wheel column changed nothing. and the best part now: - i have second f32 - 420i. It also have shimmy at 90km/h. Its ran at michelin crossclimate+ runflat 17" For me - the disc brakes rotors need to be perfectly flat - if some of you have the access to the machine that can make it flat then try it. I was in the workshop to make new disc brakes flat... mine had 0.02 deviation... and after flatening they have.. 0.03 deviation so i need to go to te guy who did it and tell him to correct it again, probably he installed the machine (cut pro 9.1), but not tighten screws equally to hub I also think the original hub may be made from a shit and that is why equal screw thightening is so important and it may influe for disc rotor deviation. However, 0.03 deviation is 'within tolerance'...but when take car up and rotate the wheel or rotor by a hand then i feel the brake pad is peels the rotor in a cycle, i can hear and feel when its touching rotor and when not. Same effect on both sides and in two cars. 428i is from septemeber 2014 (USA N26) and 420i is from April 2015 (Europe N20) Last edited by Kyokushin; 03-21-2024 at 07:22 PM.. |
