Yeah, sounds like you got a tank of who-knows-what... And shows how resilient the diesel engine is, that it will still run on stuff that is barely fuel.
No kidding. This is the first time in a very, very long time that this has happened to me - probably over 15 years at this point. Says a lot about how much more consistent the quality of diesel fuel has become as well.
Anyway, have about 75 miles on the current tank. Performance seems to be recovering, but I suspect that this is also going to require another fuel filter replacement.

At least it isn't the fuel pump.
And very relieved I am about that, too. Having just done some very major and expensive work to this thing, that literally would have been the last straw.

At the cost of fuel filters and for overall good you could use something like a facet pump or a cheap one similar to it (about $20 at parts stores or $10 on eBay to pump the tank out all at once and put all new fuel in. Here is a pic of my portable transfer/lift pump wired to battery with a push button switch. I have also used with a cut off valve to use my jeep tank to fill up diesel lawn mowers as well as my tractor. Just make sure you don't empty it all out of the jeep. Here is pic using it on jeep:

Problem is, the only other place I'd have to put the contents of the tank would be in the VW... And if the Jeep didn't like that fuel, the Jetta *certainly* won't. Hell, this whole incident made me paranoid enough that I decided to pre-emptively Clear-Diesel and Biocide the Volkswagen just to be on the safe side, given that it just got a new fuel filter on Saturday.

You could also filter the fuel and still use it if you wish even separate the water out wit
Still sounds like there could be another contributing problem if it is still putting out a lot of black smoke though. If you replaced almost all the fuel that would answer the question quickly. A couple of times over the years I had old fuel or water in fuel I pumped it out and filtered it then used it in my F350 7.3 liter diesel. That thing will burn anything!
Yep, agreed on the possibility of another issue. Going to go through all the intake connections and make sure that they're down tight when it's not 102°F outside; similar symptoms have been seen before when a clamp has worked its way loose. All of the turbo vacuum actuating stuff was replaced back in March, so am not suspecting those at this time.
And I hear you on the 'will burn anything' aspect of certain engines. I've had a Peugeot 504 and Mercedes 300TD that would practically run on melted blacktop
