Next issue! When having a poke around underneath to try and find the source of this vibration (no luck), i found a very wet front diff. Seems to be coming from above the diff but can’t see anywhere near enough.

A long shot, but any known oil leaks in this area? 1995 4.6 v8, green/tan (long gone)
2005 4.8iS X5, blue/black
2011 4.4 tdv8, black/black (gone)
2003 3.0d X5, Oxford green/black/manual
2021 p575 SVR, BR green/vintage tan

Rear output seal which is higher up on the diff? Have you cleaned it up with brake cleaner topped it up and gone for a short drive to see if you can source it that way ? Current stable:
2006 BMW M6
2007 4.2 V8 S/C FF
Gone:
2002 4.4 V8 FF

if not the diff itself, the secondary turbo sits above the diff
. Cheers, Greg

I had 2 oil leaks around that area:
1) Secondary Turbo
2) Oil pump plug.

Both rectified at Rovertune with 1) new turbo and 2) plug sealed.

It’s not using any oil at all and there is nothing on the floor after sitting for a few days.. it’s also had both new turbos.

I have an endoscope so will have a look over the weekend 1995 4.6 v8, green/tan (long gone)
