Thought this may be of some help, beware 5500 pages!
I believe this manual is for the L320. ����P1, this is redundent information and is inaccurate for for the generation it covers. 2003- 2005 are identical. Why does this leave the first 2 years off? 2006 was the unwanted step child. BMW electronics and the all new 2 Ford platforms. It really is one of year for lots of things.
2007-2009 is the third generation L322 2010 was the face lift and refreshed interior.
Why down load 5500 pages when the existing resources are factory workshop manuals and easily navigated?
