FIXED: BMW F13 640D vibration ONLY during idle speed

[Curamrda]

Hi guys..

have anybody experienced something similiar? I have 640d 2014, and I can notice quite annoying vibration inside the cabin everywhere at idle speed. Everything in cabin is resonating.

When I am going at least 1 000rpm everything is very fine.


I tried to raise idle speed +40, it helped, but not so much...

I had E92 330D and it was less vibrating then this 6 er... It is 6 series !! this cant be normal !

i have the same vibration on my 2013 640d...Engine mounts has been changed, the new non runflat michellin tyres have been balanced several times, the rims have been straightened the axle checked but the vibration insist!!!

what else should be?

Can't help with a fix but I had this also. Was surprised at how bad it was compared to my previous 318d! On top of that I also had a vibration at all speeds which meant in the end giving the car back to the dealer.

thats unbelieveable... i can see differences:

1] vibrations are really strong...that your head is in pain, when engine is cold
2] vibrations are much lower when transmission is on R or P

i am suspecting the mount of Transmisison or the hydrounit

Had exactly the same problem on idle , (droning vibrations )went in today after a day of investigation, it's a build up of carbon I think he said in the manifolds but I'm not sure,that needs removing .(de-coking)
Becoming more common on low emission Bmw diesels apparently
Bmw approved the work it's a two day strip down job, tech said its deffo the problem.
Will update you next week ,

They Bmw techs diagnosed the problem on my car 640d as ...carbon build on I think they said manifold.
I as in me am not personally stripping anything,
They Bmw techs think ( deffo) they have found the problem, and are stripping and using an old phrase ...decoking the engine next week , it ( the work) is estimated to take 2 days.
That's what the master tech told me , I hope that is clearer
Apparently this problem( vibration) is becoming more common on low emission Diesel engines
That's all I can tell you my Bmw friend ?

Is it fixed with the cleaning of carbon build up? Does it vibrate any more?

[Curamrda]

i strongly believe it has nothing to do with carbon in intake... i am suspecting not balanced crankshaft from factory.. - so not fixable...
