Tlon, thanks for the write up . . . the points you raise are indeed very valid and are CERTAINLY the ones that one should consider before venturing into a diesel for the first time.
Just out of curiosity - given what you knew about diesels, what were the reasons that got you to try a diesel?
I have a 2011 X5d and my other car is an 8-cylinder, 4.8L petrol engine. You are right about the noise - particularly the note they produce . . . IMO they are both very nice in their own respective ways, can't say I like one better than the other.
Regarding DEF warning, sorry to hear about that, I read that was a software glitch and is now fixed. I have ~24,000 miles on mine, never had an issue, and I have gone through two DEF refills during routine service visits.
Diesel availability was never an issue for me - most of the branded fuels (Shell, Chevron, etc) all list their stations and the fuel they offer. Here is the Chevron website
. Most also have a smartphone app showing the same info. I have never had to stop at a truck stop and got messy like you indicate.
Improved mileage IMO cannot be overlooked . . . for me, it translates to fewer visits to the pump!
Again thanks for the write - as mentioned earlier these are DEFINITELY the relevant issues one should consider before getting into a diesel.
My next X5 (say 8-10 years from now) will hopefully be a diesel-hybrid! Wishful thinking - doubt BMW will produce a diesel-hybrid.
