Depends on whether or not you are talking about my cubicle at the office, where I do paperwork, or the work space at the customer site, which is actually in a cleanroom.
The cleanroom space is, obviously, cleanroom clean. 5S and all that horseshit.
My desk at the office is chaos to everyone else except me.
VW's patented setup sounds far less ideal than the well understood SCR/DEF setup everyone else uses. 20% of max power to burn out the NOx trap? No way in hell would I want that!
The precise temperature controls you allude to for SCR/DEF is hogwash. You've got quite a bit of leeway to get up to temp before the system starts dosing before throwing codes and going into limp mode (think like over an hour of operation). If you didn't, then all of us in places with 4 real seasons would have diesels that wouldn't go anywhere because DEF freezes at about 18 degrees F. Where I live, we can go months with temps lower than that, and it takes time to thaw the DEF so it'll flow.
DEF consumption is 1-3% of fuel consumption. So figure 1-3 gallons of DEF used for every 100 gallons of diesel; that's for the puny little 2 liters in a VW all the way up to the 13L monsters in a Peterbilt... 1-3% of fuel, like clockwork. How many gallons of DEF would be needed to go the oil change interval on a VW TDi? Not many.
Lastly, on DEF, any fool paying stealership prices deserves to get ripped off. Drive to a truck stop and enjoy ISO rated DEF/AdBlue at $2.70 or so a gallon. My last DEF fill cost me a whopping $16 for my truck at just over 6 gallons in ~8k miles.. A 3.0L diesel truck that gets 24-27 MPG in mixed driving. A 2.0L TDi should be able to go 12k+ miles on 5 gallons considering how much less fuel they burn than my truck does.
Sounds like VW disabled EGR when not on a dyno. I know exactly why they did it.. EGR is pure evil on a diesel engine.
EGR lowers NOx emissions by lowering combustion temperature, but the downside is that they gum up the valve stems in the heads on a diesel due to the soot. Eventually the sooty crap hardens in the intake and then chunks break off and go into the combustion chamber and act like sandpaper or rocks, scoring the cylinder walls, worsening everything.
EGR works well on non-direct injected gasoline engines because they "wash" the soot with fuel before it can cake the valves, but is very hard on diesel engines from a longevity standpoint since no fuel touches the valve stems. EGR lowers power, and increases fuel consumption to lower NOx.
I've got a "small" diesel, in my pickup, and it has DEF (urea) injection on it. VW owners should not fear DEF. I fill the DEF tank on my truck about every oil change, from bulk dispensers at the truck stop, for a whopping $16 every 8k miles. I average about 1500MPG on DEF, and about 24.5 MPG on diesel fuel (full tanks, not pure highway). Pretty good numbers for a 6000 lb 4x4 pickup truck.

Don't have a 1GB USB stick and a web browser to update it yourself?
Take it to the dealer, takes about 20 minutes.
Wait until your USB stick shows up in the mail and do it yourself.
Tesla's Warranty is a bit better than what GM offers, true. However, it is not hugely better excepting the unlimited mileage for the powertrain, and 8 year battery warranty. That said, I've got some concerns with Tesla's battery warranty being that I live in MN.
"In addition, damage resulting from the following activities are not covered under this Battery
Limited Warranty:
â Exposing the vehicle to ambient temperatures above 140ÂF (60ÂC) or below -22ÂF (-30ÂC) for
more than 24 hours at a time;"
That bit scares me. -22 F temps are normal for us in the winter, and I don't heat my garage. Thus, the car would be exposed to such temps for over 24hrs at least once a year. Kind of puts a crimp in my plans to buy a Tesla 3 when it comes out; I can already make the justification to buy a model S based on my driving needs, but I refuse to pay more in car payments than my mortgage.
From Chevy's website:

Sheet Metal:
Corrosion coverage is for the first 3 years or 36,000 miles, whichever comes first.
Rust-through coverage is for the first 6 years or 100,000 miles, whichever comes first.
From Tesla:
Subject to separate coverage for certain parts and the exclusions and limitations described in this
New Vehicle Limited Warranty, the Basic Vehicle Limited Warranty covers the repair or
replacement necessary to correct defects in the materials or workmanship of any parts
manufactured or supplied by Tesla that occur under normal use for a period of 4 years or 50,000
miles (80,000 km), whichever comes first.
Supplemental Restraint System Limited Warranty
Subject to the exclusions and limitations described in this New Vehicle Limited Warranty, the SRS
Limited Warranty covers the repair or replacement necessary to correct defects in the materials or
workmanship of the vehicleâ(TM)s seat belts or air bag system manufactured or supplied by Tesla that
occur under normal use for a period of 5 years or 60,000 miles (100,000 km), whichever comes
