Oil leak from turbo outlet flange (B47, 320d G21)

[andy1316]

Hi everyone,

I’ve noticed an oil leak coming from the turbine outlet flange area on my BMW 320d xDrive G21 (2019, B47 engine). The oil seems to be coming from the joint between the turbocharger and the downpipe.

Has anyone had a similar experience?
 

Any help or experience with a similar issue would be really appreciated.

Thanks in advance!

Welcome to the Forum

Unfortunately the only solution is to strip it all down and then find it is a £0.50p gasket (hopefully)

Good Luck

Hi Dave,

Thanks for your reply!

Removing the turbo is not that challenging. The challenge is to find the right gasket..

And here I’m a bit helpless, since no.8 on the drawing does not fit there.  Looks like there simply isn’t any gasket..

Hi Andrew 

Are you using www.realoem.com ? The drawing looks like it or is that from the Internet? 

Is the turbo fitted OEM ?

Hi Dave,

Sure, realoem.

Part number (steel gasket) is 11628576287. 
and according to the second drawing (please see attached), this is the EGR Line Gasket.

The plot thickens

I have changed 2 Turbo's on friends cars but in both cases they were refurbished Turbo's brought as the OEM ones were beyond help. And were  fairly straight forward (grazed knuckles) to change. Could the leak you spotted be coming from the Oil Feed pipe ?

Thank you for your interest in this topic. There is some hope that a solution can be found through joint efforts)

I eliminated the oil feed pipes.Since the first thing I did was replace the sealing rings there.

I am attaching a few more photos showing the leaking area.
