In my opinion, polluting less isn’t a bad thing, nor is reducing fuel consumption to reduce both greenhouse gases and reliance on imported oil.. We are in a golden age of performance with out the traditional downsides of poor fuel efficiency and pollution. Why spoil it by being a cheap SOB? There are plenty of gas powered German SUV’s that tow well, have good performance, and which can be tuned for even higher performance without disabling their emissions systems. . . if you can’t afford the upkeep on a diesel X5, then you should buy a gasoline version. Just a personal opinion...

I love that there is always an assumption that someone can't afford to own one. For the record, I have not deleted or tuned my X5, and I don't support full deletes as it does make the vehicle a bigger polluter. That being said, I'm not necessarily against EGR deletes, as it is largely inactive at driving speeds, and can be a major contributor to serious negative carbon buildup issues. Nor am I against mild tunes that still use the SCR and DPF systems to keep tailpipe emissions clean, while making some additional power.
That being said, its no secret that today's Diesel emissions controls have LOWERED the efficiency of Diesels, the benefit obviously being cleaner tailpipe emissions. I don't think Diesel emissions controls are at the place of gas emissions controls however, where they really have gotten to a point where you don't have to sacrifice power or fuel efficiency, nor is there near the problem with extremely expensive, out of warranty repair issues with gasoline engine emissions control systems.
Whether someone CAN afford to replace high dollar DPFs and SCR systems or not, it is not reasonable to have to expect to take on these expenses at such early intervals (often times under 100K miles). Thankfully some warranties have been extended, but its still sad if you think about it that you can expect these systems to fail again (now out of extended warranty, but well within reasonable expected service life for the rest of the vehicle).
Then there is the hassel involved with having to take on these repairs because the systems have not been engineered and produced to have an acceptable level of reliability.
This has effectively driven many owners to deletes not only as a more cost effective alternative, but also to relieve themselves from the constant headaches of the unreliable systems. When you consider the economy and power gains that can be had versus continuing to replace high dollar emissions parts, it becomes even more enticing.
As for your suggestion to just buy gas? I'm sure we could all be happy with the gas version, it's no slouch. But even with the lost efficiencies of modern emissions control systems, the Diesels still hood a significant edge in fuel efficiency, and torque output.
Anyone want to bet all those 'Rolling Coal' idiots have brought these modifications to the attention of the feds more than anything else?
