F10 vibration in driver seat when doing between 70 to 80mph

Hi Guys as per the title my f10 520d msport with factory 19" rims has a strange vibration in the drivers seat when driving between 70 to 80 mph. No amount of balancing seems to make it better. And ive read that this is a problem that affects the f10. Does anyone have this problem with their f10 and what is the soloution? Thanks in advance

 

I felt the same when I got my f10 530 but getting 4 wheel alignment and all wheels balanced along with swopping from run flats 100% improvement

 

Hi There
Have you removed and replaced any of your wheels recently, I had a similar issue above 70mph, the cause was the dealer not cleaning the brake rotor when then tyre was changed, if the alloy has been in one place for a while, and the rotor has rusted a little, then if you put the wheel back on and it’s not in exactly the same position it will cause it to vibrate, worth a try as a cheap fix.

 

Reminds me of the E39 'shimmy' issues, where some examples could be very sensitive to any wheel and/or hub run-out, imbalance or slight suspension wear. Wheel mounting accuracy was a critical part of reducing and eliminating shimmy. Doesn't take much of a mounting error to amplify the problem at the rolling frequency bands where we get shake.

Even road force balances, which help in a lot of problem situations, can't always correct some wheel and tyre issues.

I had exactly the same issue on my F10 520d MSport from when I bought it a year ago.
I changed tyres, all the brakes, suspected buckled wheel so I bought refurbed wheels but nothing solved it.
Then last week the lower coil snapped on the rear spring. I had them changed for BMW original parts at my local indi for £375 including the springs and the wobble has dissappeared. The car drives sublime again. Rear has firmed up too.
The road force thing is junk, don't waste your money.
Hundreds of people seem to be having this issue please spread this solution.

 

As posted in your other thread, besides the spring, what was your solution?

Just the rear springs Peter
That’s it

 

I multi posted Peter as so many people are having this exact issue

 

The spring won't be responsible for wheel vibrations in the typical wheel frequency speed range, The spring is associated with the vehicle body harmonics. The wheel or some other rotating component is the 'generator'. Are we seeing a more precise wheel mounting in your instance? IMO, the 'outsider' in the problem solving path, would be the replacement spring fitting, required disturbing suspension components and they have settled in slightly different positions, possibly masking a bit of wear or softness.

Quite possibly Pete but the act of changing springs has been my solution.

Very happy

 

It is a good solution, whatever the cause.

There are similar issues with the G30 models. Wheel vibrations even with different wheels, precision balancing, etc. What is also clear, the mounting is critical. Even with hub-centric mounting we have on the BMW models, there is enough clearance between the hub spigot to rim centre bore, (maximum allowable by BMW is 0.15mm), to cause vibrations. Guys are taping the spigot to get a more precise fit. Adding BMW's friction disc, along with precise cleaning and torqueing before loading the wheels. Seems every little bit helps.

This is much the same as we had with the E39. Everything had to be precise, or vibration and shimmy couldn't be eliminated. Any wear or errors, and the situation was amplified.

It can be a pain, as everything may look okay, but vibrations occur somewhere in the critical 60 - 80mph speed range.
