Any instruction or diagram how to remove intake manifold?

So you have a pre-facelift car - earlier than Sept. 2003?

Here's the instructions for removing the intake on the M57...

The newer M57TU is here...

This video show some of the items you'll need to disconnect - it's for an X3 E83 3.0d but very simliar to the X5 E53 3.0d (i.e. same basic engine).

Three items of note...

Firstly, the rail pressure sensor can be seen clearly (to the right of the EGR) in the front views starting about 30secs into the video, even with the intake manifold in place. It's likely that you can remove this sensor without removing the intake manifold.

Secondly, if you DO remove the intake manifold, be VERY careful when lifting the manifold clear of the mounting studs - the gaskets are known to fall off the manifold and drop into the engine's intake ports!

Thirdly, the X3 video linked above shows the intake manifold has swirl flaps. The M57/M57TU (aka M57N) as fitted to the X5 E53 does NOT have swirl flaps, so don't bother worrying about them.

Here's a couple of pictures from my own car - an LCI model, so engine is an M57TUD30. Red arrows show the fuel rail pressure sensor, yellow shows the fuel pressure regulator. Click the images for a larger version.
