525d F11 - Heavy vibration after shift from "R" to "D"

Makker · 04-19-2022, 05:16 PM

Hey everyone! Hope someone know what it could be or have had the same issue as i have Heavy vibration after shift from "R" to "D" only sometimes.

I have 525D F11 - 2012/2013 N47 engine and automatic trans with 165.000KM.
Some weeks ago after reversing from my driveway, and changing to Drive, i heard a "KLONK" sound from under the car. And after that, as soon as i accelerated, the car was vibrating very much, it felt like i was driving with the handbrake pulled, then it kind of dissapeared when i got over 50km/h, but when i stopped at a section and had to accelerate it was back vibrating. Next day it was gone. Afterwards the vibration happend like once a week. I kind of felt it was provoked when i changed a little too fast from "R" to "D" before holding completed still, but not sure... I also found out that, when the vibration start, i should just stop the car, reverse a bit and then change to kind of slowly "n" and then "D" and it would go away just like that.... What do you think it could be? It sound really bad. A mechanic said either something with the driveshaft or the transmission. i hope its not the transmission. But other than that car is driving perfect, no fault codes, transmission is shifting good and it was flushed and oil was changed 20.000KM ago. Flexdisc has also been changed.

Hi, this is definitely not a transmission problem. If the transmission shifts gears well. The reason may be Silent block rear reducer, or Flexible coupling.https://www.fcpeuro.com/products/bmw...RoC5l8QAvD_BwE

Quote:

This rubber flex disc sits in between the drive shaft and the output shaft of the transmission. It helps absorb vibration while allowing slight flex. This particular component is known to tear or crack as it ages which will cause excessive play within the drive shaft. This will cause excessive noise and vibration. We recommend periodically inspecting this component for cracks or wear.

I also have the same issue but only in colder months, I have been advised to check the motor mounts.

The flex disc has just been replaced, and it is still doing it. i will try with the Silent block rear reducer. But i just had a by a BMW guy, and they reset the transmission, and gave the car an software update of all modules. Didn't work. They came to the conclusion it was something mechanically inside the gearbox, and solution would be new gearbox...

So does it only happend occasionally, and only when you go from reverse to Drive and at low rpm = high vibration ?
