G'day Dan,

As JCL says, the most comprehensive E53 manual is the Bentley. Unfortunately there's no specific coverage of the 3.0d engine as the manual is produced essentially for the North American market

The cargo blind and the safety net should be both available at a BMW dealer, but expensive. Otherwise it's ebay etc.

I haven't done a software update on my gearbox, but this is covered in much detail in the general E53 forum. Do a search. Just be aware that the post-2004 3.0d had the same ZF gearbox (ZF 6HP26) as the post-2004 4.4 V8. This is a different auto from the 3.0i and pre-2004 3.0d and 4.4i.

Good luck with it.
