I topped off my daughters 2017 jetta SE with some G12+ I had from previous audi p/n G012A8G1G. I didnt look at specification as what was in the car looked pink to me. Probably put 3-4 ounces in as it was slightly below minimum mark. Afterward I looked up and see that it calls for G12++ which supposidley is not compayable with G12+. I think I should be ok as I only added a small amount. Whar makes these two incompatable

Wow so it didn't call for G13? I thought all G12's were compatible, just improved formulas? This is ridiculous.. I just bout a 2013 TDi and am starting to really get perturbed of VW's specs for unobtainable fluids....

507 spec oils, good luck!

I'm curious what special materials they are using that forces the need for such a boutique antifreeze.

Despite having been flamed in the past, I still think vehicles use pretty much the same materials in their engines. So, any modern antifreeze should suffice. It's when mixing them you can run into troubles.

I mean, they've been using G12++ for over 10 years now. It's not like it's exactly new. I agree that keeping the names and color so similar (G12+ /G12++) was pretty stupid, but this isn't exactly a hard-to-find fluid.

And most transmissions use proprietary fluids these days--and there are plenty of DSG fluids available: https://www.fcpeuro.com/products/audi-vw-dsg-transmission-service-kit-02e305051ckit

No offense intended, but I think it's a lot of hand-wringing over nothing. If you're able to read this forum, you should be able to order the correct oil, coolant and transmission fluid pretty easily and inexpensively.

I just needed some for my 18 Passat, the reservoir was marked G12. There were a few offerings available at parts stores but it was confusing mumbo jumbo so I just went to the dealer instead. They sold me a jug of G13 and showed me the screen where it was listed as correct for my vehicle by VW, and it is supposed to be backwards compatible.

The 2018 takes G12++ or G13 not G12, they probably left the ++ off the cap. G13 is 100% compatible.

Your 2017 Jetta should spec G13 not G12++, as G13 was introduced more than ten years ago now to be used across the whole range.

However G12++ and G13 Have the Same corrosion inhibitors, the only difference is that G12++ is 100% Ethyene Glycol, G13 is 80% Ethylene Glycol and 20% Glycerin.

G12+ and G12++ are perfectly compatible too, G12+ is an OAT and G12++ is a HOAT With Silicates but they are compatible.

To add to even further confusing VW has yet again changed their coolant, from late 2019 all new VWs come with G12 Evo! a newfangled HOAT coolant made by Glysantin with Silicates and Phosphates.

Nope

G11 and G12 are not, if you mix them you will get the same kind of result as mixing Conventional Green with Dexcool.

G13 was the newest formulation, now they have a new one called G12 Evo, i'm not sure wether all new VWs come with it or some are still on G13.

We were talking about G12. I should have been more clear.
