Hello,

My B47 suddenly makes strange noises just before it comes to a standstill. I recorded this once and can't identify the source, maybe someone already had it.

It can be heard in the last seconds 7-8, a knocking shaking noise.

They only does that when the engine is warm. It doesn't do this when it's cold. He always used to go out with a gentle Frrrrr

I have replaced all Seals in the Air System and the result was the same.

But i have find out that the nois comes only in Position " P " , if i shout down in " D " or " R ", the engine stoped perfect.

Is there a problem in the 8HP gear box?

Perhaps it doesn't do it in D or R as the transmission still loads it long enough to prevent it.

also the same in Stop&Go shout down, no noises. Only in Position P

Hey, not much help, but I came across this thread seems to be talking about the same issue that you are describing:

FWIW I never put my car in park before shutting the engine off, I always leave it in gear and let the car put itself in park when I turn the engine off. The car doesn't mind it a bit.

Yes i know, but there was no result till yet

So, I just had the car on stage and it was always turned on and off, the gearbox swings back and forth quite a bit when turning it off/on. The noise comes from the very back, near the hardy disc flange. There is no oil leak there either.



I'll change the transmission mount tomorrow and see if that helps. Visually they don't look defective, but that doesn't mean anything.

It's unbelievable what I've just discovered. The wrong transmission mounts are installed in the vehicle.

In my pictures you can see that the 6875904 are installed, these are actually for a petrol engine and are much softer than those for the diesel.



The correct number would be 6796617, this was never changed by BMW. I think in the past the bearings were replaced and incorrect ones were installed. These move a whopping 8mm more under max. load. Both are visually the same, but have a different rubber mixture.



Well, I'm excited about the change.










Here again is my storage of what I need:

I had to delete the link again, the page then goes to Leebmann's unfiltered page with all the locations there are.

But all the BMW dealers in North Rhine-Westphalia I called always said "not available at the moment" until the end of March. Great, I would have liked to pick up the stock from my dealer for €24. So now Leebmann has to wait.

Here is proof again that it is wrong that 6875904 was NEVER installed in the F34. I left the engines hidden in the picture, but believe me, there are no diesel engines.

the parts are OK , i have take a look onto the drawing, 4 part numbers are printed in the rubber.

today i have change the mounts but nothing has change

I have called ZF and they think, that the parking brake hase some issues.
