All,

I'm very interested in buying an e70 X5 xDrive35d in the not-so-near future. I'm trying to research as much as possible, as I always try to do for a major purchase.

What I'm having trouble finding is specific information about the changes to the diesel engine throughout the production years.

It looks like, globally, the diesel engine changed a bit during the facelift, but in the US market, it "remained unchanged".

However, I'm seeing lots of threads and reports about the emissions systems on the earlier engines being much more troublesome than the later engines.


Is this a simple matter of "later production = bugs worked out" or are there any advantages to the earlier engines?

Is it all in peoples heads?


I've tried to search on the topic here, but most of the threads that come up are from 2013 when everyone was excited about the facelift changes and there was lots of hearsay with little fact.


Thanks in advance!
