I am not much of an engine technician, but I'll bet some folks out here are. Diesels have a reputation for lasting a long time. Will the X5 diesel have a longer life than the regular gas engines?

As I rack the miles up on my E70, I am pondering if the next one will be the diesel or not. My biggest concern with the E70 is maintenance costs in the future (and the associated hassle).

Granted most of the X5 issues are not with the engine itself, but I'm curious to more about diesel engine maintenance and issues compared to the normal gas engines.
