IIRC the 3.0 litre diesels are described as third-generation engines.

I wonder (apart from the number) what that actually means?

Now that's a very good question...
Let's see if we can figure that one out...

Here's some a link to some recent blurb on the 320d... (the 320d with the 163hp engine is referred to a 2nd generation as well)

Now what is it missing or how is it different from the new '3rd generation' diesels described on
http://www.worldcarfans.com/news.cfm/newsI...celift-in-depth

It seems that the 'nth generation' refers more to the 'common rail system'
- piezo injectors are called out explicitedly on the 3rd generation 3.0 diesels released in the E90 and more recently announced in the E60
- however, I can't find them mentioned in any descriptions of 2nd generation common-rail
- any most other things common-rail-related look more or less the same (they both operate at max 1600bar etc.)
So, could it be the injectors?
