Hi guys.
The other day i was out driving and when i turned down the stereo i could here that my engine didn?t sound as it usually do.
There now is a huuge turbo sound. My guess was that there was a leek somewhere, but didnt found anything. Try to presure it with 1 bar, and it dosent leek.
So today i have worked my way down to the turbo. It has a small gap, meaning i could move the impeller 1mm up and down. Nothing out and in.
Is that ok?
I wondering however there is a lot of oil everywhere. Some in the throttelbody, almhost in any tube, if i put my finger in and swirl it around, i will get really black.
Is the turbo worn? What else could it be?
Its a 530d -04 with 140000km

About the turbo axis play, I can only say that normal turbo has play just as you describe it but how much I dont know. It normally is a little radial play but no axial play whatsoever.
Start looking for a turbo rebuild kit or a new turbo. And dont forget to empty your intercooler for oil.

Hey, guys, here comes a small update so you have something else to think about
This is done:
* New crankcase vent
* Tested for leaks
* felt the turbo front and rear, and looked impellrar no visible injuries, just a little gap
* EGR bypass / plugs
* Check error codes, none found.
* Removed all the multi-straps
Tested today to snatch the cabling to the waste gate afther that the car was completely dead, but noise disappeared almost completely. The oil is completely normal what I understand, not much.
When the cable was connected again the noise came back... Same as the turbo boost.
Edit:
There is no smoke or something...
