Yes what is causing this issue of crusting up? I have a jetta and just did the frostheater install yesterday and today. Didn't notice anything unusual on/in the oil cooler nipple at least, only 34k on the car. If it's lime scale then an acid should dissolve it, muriatic acid, believe I seen at Lowe's or hd or a place like true value. I've used it to clean metal prior to soldering back in high school.

Drained my coolant for the second time in 2 weeks. Reservoir was once again filled with sediment. This time however I drained it to install my new weapon...
I used a coolant filtration kit for a 6.0 powerstroke. I had to make my own 5/8 to 3/8 tee and modify the mounting bracket. The other one included for 3/8 at the bottle worked with the 5/16 line. It must be working because it gets hot! Hopefully this will resolve my issues.

767 nice work. Is there any consensus on an inexpensive pH test kit or effective flush? I have not experienced any issues (yet) at 76k miles and am thinking about multiple cooling system flushes with water when the freezing temps are gone. I'll probably run a day at a time (~140 miles, 3 hrs) with straight water and keep repeating until it runs clear. Wondering if adding some vinegar or lemon juice might help with dissolving deposits???
I have been experimenting to see what will remove the buildup on my old oil cooler. So far dishwasher cleaner and full strength radiator flush have failed. Im not knowledgeable on ph levels and that kind of thing. Im more of a believer that the coolant is getting too hot in the egr cooler causing the coolant to break down. It doesn't really look like aluminum corrosion in my opinion.
That kit is expensive. I think I'll just source the adapter and the filter spins on from Amazon, and use $1/ft hose and $2 fittings. Spot weld my own $80 bracket with some holes.
Hope vw gets settled soon, I planned to swap heater core, oil cooler, and install a filter somewhere.

Never ever run non G12 or G13 coolants in a TDI.....
Cooling system issues are never a thought when using G12 or G13.
Anyone that attempts to use a non G12 or non G13 coolant had better read this thread to see what they can look forward too!
VW is clear, mixing coolant types Will result in clogging of the engines cooling system aka the brown goo!
Lol do some more reading around this forum there pro. All kinds of issues with the factory stuff. Hence the change to green organic acid and no more issues

To me, switching to 100% green may resolve the current clogging issue (remains to be seen if that is true) but what does the green do the the surfaces it contacts that pink doesn't? Must be a reason why VAG uses that pretty colored fluid. I'd be worried that it would be eating the block or something.

Update: 30k miles on my "B" replacement heater core. Now at 50k miles, coolant still bright pink, no cabin heat issues. Engine temps stable.

Just to get you caught up, all of the problems in this thread and the clogged heater core thread are with the FACTORY VW G12 and G13 coolants. Volkswagen clearly has a problem here, and it isn't with owners putting in the wrong coolant.
Green stuff with additives for aluminum. Done.
Especially if running with deleted egr cooler. No more stupid high Temps hitting the coolant.
The way factory g12/13 is giving issue , I don't think it can handle egr Temps.
Maybe old school green with a few additives is better, deleted or not?
