No, nothing I've done makes any difference.

Had all new tyres twice in my ownership

Just crawled underneath.

The one side of the diff box is oily, the otherside clean.

Also, one of the driveshafts I has definitely been replaced (on the clean side)





Not sure if its relevant, but it obviously been messed about with

Close mate of mine has an M135i from new until tomorrow, 3 and 1/2 years old. For the last 2 and 1/2 years it's had this exact problem. Paid over £30k for the car.

BMW said he had damaged a wheel at first. He spent £1800 on a new set of quality aftermarket wheels - didn't fix it.

BMW swapped a few parts over from a 'spare' M135i in the workshop. But eventually sacked him off with the same charactertic of the car bullst they've given you. He's sold it on to another group at a significant loss and committed to a new Japanese car hoping they are not made from chocolate and their dealers are not s.
This is why I drive a Subaru, it might not be as flash as a German car but its reliable and I have confidence in driving this around the word (and back) without any major mishaps.

Japanese cars just cant be beaten for reliability but the majority of the UK seem to have something against them and instead think buying German marques make more sense, I think not.

What gets me is that the dealers deny the issue

I have an MB CLS with a vibration problem.
Interestingly, Its not a problem with the winter 17" alloys/tyres and a pleasure to drive.
When I change to the summer AMG fat tyres, the vibration returns and its really annoying.
I've had the summer set up balanced and checked and its correct.
I'm pretty sure its a wishbone bush issue on mine.

I'm going to say it's the guibo. Does it still happen if you're going 60-80mph in a lower gear?

Yes.

Though isn't the prop related to road speed only?

BMW have come back and said they recommend having the wheels balanced (after they remove the locking wheel they put on too tight and now won't come off)

Also, any issues on the F12 are NOT related to the F10 (I'd imagine the drive train is identical)

Typical, as its gone out of warranty this week

Its a Giubo. Hate to be a spelling nazi but it's not been spelled correctly a single time in the thread.

Yes it's meant to be giubo but just about everywhere you look these days it's mistakenly written as guibo, The incorrect form is far more prevalent than the accurate term so it's no surprise to find it in common use! We know what we mean etc.

If you brake very gently whilst it's vibrating do you feel a pulsing through the pedal?

I'd be surprised if it was the propshaft Giubo/rubber doughnut - There would be obvious signs of deterioration and tend to wear on older high milers.

For me is the elephant in the room - the buckled wheel. I know someone has said that it's not bad enough to cause vibration but if it's slightly buckled it could well be out of round too.

I'd be trying/borrowing a replacement wheel first.

It's easy to go rushing into all sorts of components, but a vibration that can be driven through is highly likely to be wheel balancing.

You need to eliminate the commons things first and the buckled wheel is the obvious item

I've had them balanced at numerous places & on a hunter machine.

BMW also swapped a set of wheels and noticed not change (whilst also funnily enough not admitting that there's a vibration)

But, you're right until I get this wheel off, I'll not know about that wheel, however, the vibration been present, I've done 20k in my 1 year ownership, current mileage is 61k.

I'll just have to wait to see what they say, I just get feeling that they don't want to be bothered and just recommend that it has the wheels dynamically balanced which isn't a service they offer

There's a slight wobble, In fairness they've already replaced the front discs under warranty

Sticking brake caliper piston?

Propshaft balance/ doughnut?

Faulty driveshaft, balance or damaged CV joint?

I renewed a driveshaft on my nieces car using a reconditioned respected name part, it was faulty and caused symptoms similar to yours.

Chances are the joobo or gweebo ( taKe your pick smile ) is ready for replacement anyway, it's a useful first base job to get done.

I'll ask them to do it, no doubt that somehow they'll not be responsible for the cost.

Fingers crossed, anyway thanks PH

It won't do any harm. I've reached the point with three BMWs where I suspected that this particular component was in need of replacement and in each case it was. Driving characteristics improved each time so I've never considered it a waste of time / money.

If you've got a buckle, no matter how slight, that's where I'd be looking.

I'm incredibly sensitive to wheel vibrations after having had an E39 which did it and even a relatively slight buckle is something I can feel.

Sorry if I missed this but what's the mileage on yours? The one repair that has previously made a massive difference to my previous cars was new track rod ends. Both times, it felt like driving a new car afterwards!
