The AdBlue liquid is pretty cheap in the EU and is not taxed. Also, the amount of AdBlue that is used depends on how you drive the vehicle too.
Mercedes will make keeping the AdBlue tank full as part of the normal maintenance routine and will probably cost next to nothing or nothing at all. Mercedes charges somewhat less than $1000 for the diesel option. Dodge charges a bit over $5000 for the diesel, plus whatever required equipment (trans, heavier front suspension, etc.) which in the long run still makes it cheaper than buying a large gasser. The other thing about that site stated something about X miles year after which point diesel starts becoming much cheaper to run. The calculator looks at first year only as I read it. You be interesting to see the return after five to eight years at 30K miles per year.

I use one additive, a cetane improver and that is it.
The diesels also seem to need time to cool off after running in hot weather. Ford suggests letting their diesel engines idle for 3 minutes before shutting them off. Sounds like a hassle to me.
Any turbocharged engine, gas or diesel, needs to be allowed to idle and cool after being run hard, such as towing at high speed or running at high speed in hot weather. Again, this applies to any turbocharged engine.
Cold weather starting. Your example smells like a GM product. (Does Ford use two batteries?) I had a diesel in the early eighties and I never plugged it in. It had one battery and would take 3.5 seconds to heat the glow plugs even at -20F! Always started unless the battery crumped. I have the Liberty and it lives outside without being plugged in. Glow plug preheat is two seconds or less in single digit still air cold. Starts first try and runs smoothly. The old diesel did too. I am off and moving in 15 to 20 seconds without a hiccough.

..."I use one additive, a cetane improver and that is it."...
Since I am a relative newcomer to passenger vehicle fleet diesels, (actually my FIL had a 1985 MB 300 TD) folks can correct me on the history. But the real reason for the NEED/want for the cetane improver was because of the mistakes made in the 1970's by the regulators. Essentially as technology improved, vehicle cetane requirement ratings (on the diesel side a tad analogous to octane ratings) went up. So for example the 2003 TDI had a cetane requirement for a min of 49 cetane. USA law allowed (relative to Europe) much lower quality #2 diesel, with 49 state cetane of 40. CA had of late before the ULSD, had 45 cetane. ULSD I read in passing is now 50 cetane min. So not only does it have WAY less sulfur 15 ppm vs up to 500 ppm, but the cetane rating is UP.
I have also been in 20 degree weather and once in 20 degree weather with a wind chill of essentially ZERO (at altitude in the CO Rocky Mtns) and once the glow plug dash indicator light went out the car starts IMMEDIATELY.

With temps. as low as -50 F windchill I've never had a problem with either VW TDI or Liberty CRD starting or with fuel gelling.
I always use a anti-gel, lubricity, cetane additve year round. #1 reason I use the additive is for the lubricity additive for the injection system.
The old adage an ounce of additive is worth 10 hours labor $80/hr.

So that I am clear to the NON diesel folks, I DO NOT use a winter additive. Nor do I do anything to remotely approach #1 diesel.
Yes, I also use the additive( Cetane booster Primrose 405C 1-3000 dilution,
I keep it in a 12 oz? bottle in the trunk and give it a quick shot just before filling (when I remember), little to no hassle.
I decided to use it in 2003 due to the VERY poor grade USA #2 diesel fuel. In theory, its use with the new ULSD is a complete redundancy. However, I still use it for the supposed extra lubricity to the fuel pump, as my longer term goals for this vehicle are a min of 500,000 miles and hopefully to 1,250,000 miles.
So if I were to keep the TDI like most people keep their gassers (to 250,000 miles), I couldn't be bothered. So in truth, I would have a hard time telling folks it does/does not work. Ask me at 500,000 miles or I will mention it if and when the fuel pump goes DOA.

The link to the additive package appears to be broken.

Hopefully this will work. One will have to scroll down to the specific product (405C)
To the non diesel community:
Perhaps it also needs to be mentioned that those folks sell directly to retail and wholesale jobbers as well as distributors of #2 and #1 diesel.
When was the last time one heard of that happening on the unleaded regular premium side!!?? There is literally no way one could have access to the the same similar additive packages on the gasser side.
The upshot is this stuff can be SAFETLY shipped by UPS, Fed Ex, USPO. etc.

I check in here regularly for a little information (the net is a better source) but more for the amusement. Now every defect in diesel is a plus every plus of gas is a defect. At least I get my laughs for the day. Now I will go over to World News to find more of the same.

Actually what is amusing is there is really no shortage of unleaded regular and premium; even as we import upwards of 60% of USA oil for higher on the hog unleaded regular and premium. The real key is to convert to diesel and keep the lower diesel fuel prices and be able to do per mile driven 25-35% cheaper than like model gasser!
Some signals in the USA that the majority of segments are really serious about dropping consumption is when: diesel (alternative fuels) are tax less and cost less per gal RETAIL than unleaded regular. Curiously enough diesel is on par with premium, or in some places even less!
