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?

Im bringing it back to the dealer to see if they can do something. I want to see if an alignment can fix it. Ive read the Toe can be off and cause this. Dont think its the steering rack as users have had it replaced with no fix.

Anyone got any other ideas on a fix?
That's a great video that shows the problem, along with the speed that it occurs. This issue has been present on every F30 I've driven, and the cars have had different suspension, tires, and wheels. It must be a design flaw in the steering, and it seems the best that can happen is it gets dampened by all the suggestions here: balance, tires, wheels, meditation, etc.

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 ?

I would say you start seeing a noticeable difference at 5-7k miles. When I put Driveguards on the car at 10k miles I immediately noticed less of the shimmy also. This leads me to believe that quite possibly these cars are developing flat spots on the tires due to time in transit and sitting on the dealer's lot. Is it possible that RFTs are prone to flatspotting?

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

Pressure can make a difference. A good static/dynamic balance can be made, even on a tire that is not round. If the tire is not round, it can cause more vibration as the pressure is increased. There is not as much flex in the structure to absorb the run-out, which is the cause of the vibration.

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.

Very true. My wheels were quite bent and after having the worst two straightened the vibration was dramatically improved. New wheels were still a night and day change from that.

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.
