VW can only deny warranty strictly related to the part failed so if like your HHFP went out they can't use DEF as an excuse to deny warranty of a totally un-related part.
Sorry, nonsense. The composition of DEF is specified in the EPA regs. They are required to make it to spec, and they can't add any "special sauce," not even dye, to distinguish theirs from all the others. It is ONLY urea and distilled water, at a fixed ratio, and there are no variations allowed. The result is that DEF is a commodity, one brand is the same as any other. There is NO difference in quality. Buy the cheapest one you can find; you are getting exactly the same stuff as the most expensive brand you can find.

As for DEF vs. HPFP, at no point does the DEF come in contact with the HPFP, so there is never any reason why the one should have any bearing whatsoever on the other.

The only issues with DEF is (a) whether you are actually buying DEF, as some folks have been known to buy a jug, pour it into their truck, refill with tap water, and return the jug to the store for credit; and (b) when pouring it into the tank, some idiot has managed to add grease, oil, or plain water in the process. Some folks can't take a whiz without hosing down the entire room, you know what I mean?

The system itself isn't the problem, it is that "no start" "no more driving" bullsheit that they are putting into the program. If there is an electronic way around that or they weren't so draconian, then these systems wouldn't suck so much. But the programming takes the position that if the vehicle is allowed to exist AT ALL without this tank of piss, then thousands will die, polar bears will melt, and the sky will fall.

Yes, the VW management lied about the pollution levels, but 12 times almost nothing is STILL almost nothing.

This is what I'm using. Less than $8 for 2.5 gallons at Walmart.
The half gallon bottles are $15 / half gallon or $27 / 2.5 gallon at dealership.

I just put that Supertech from Walmart in my Golf a week or 2 ago - screw the flexible hose on the outlet of the jug, insert hose into DEF fillup port of car, then lift up and pour DEF into car until jug is empty. Easy peasy.

I get DEF at Rural King. They've had several different brands (and, yes, they've been ISO blah-blah), and it's $6.99 for 10 quarts. Cheapest place I've found, and the car seems to like it just fine.
