BMW 520d 2016 vibrating at high speed

[9inchlynch]

I was test driving a BMW 520d. Loved it until I went over 80mph and then felt a roughness/ vibration

Dealer )Approved Used ) reckons it’s a case of rebalancing the rear wheels

Any advice?

Wheel balance would the first thing to check.

Well don't go over 80mph, then. It's illegal after all...

[littleredrooster]

And why two threads for this? Did you want answers in stereo?

Bet it’s the guibo/ doughnut. Don’t buy it OP. Many many stories of owners who NEVER get this fixed as BMW don’t recognise it as an issue

I'm surprised it took until you were doing 80mph to notice the vibration/roughness, I noticed it straight away in mine when it was idling!!

A hateful engine that ruins a lovely car for me.

My M3 does this above 80mph and it depends on the surface as to how bad it is, but it tracks straight and is stable at high speed I've put it down to a the wheel been slightly out of round but if that is the case wouldn't it do it at 50mph? The sensation could be described as a gravelly feeling through the steering wheel and pedals.

What does OP mean?

I have a similar issue with what sounds like a knackered wheel bearing but isn't. I'm told it is simply the way the tyres have worn and only solution is to replace, but they are visually fine and have been assured they are safe, just noisy.

Having said that, whoever owned my car before me could not park to save their life so that wheel refurb I promised myself 2 1/2 years ago may be the solution.

Thanks a million, I’m new here! I’m hoping the dealer will put everything right for me before I part with the cash.

I’ve seen a lot written on other forums about bent alloys

Going to retest on Wednesday.

Run flat tyres that have been run Whilst....flat can cause vibration. Sometimes the case they are driven on to the fitters, repaired and then put back on but damage can be caused to the inside wall.

I took it out again today and it was 100%

Why thank him? That’s just not true.

Firstly, there’s no tyre repairer would repair and refit any tyre without checking for damage. Easily done and definitive.

Secondly, if the tyre is undamaged, it can be repaired quite satisfactorily and will retain its full performance.

Finally, the chance of one being repaired is minuscule. Most tyre repairers will avoid an RFT repair like the plague, it’s more profitable to replace and, frankly, urban myth such as the foregoing only makes it easier for them to do that.
