After that, you can run generally whatever universal coolant you'd like. I do a universal Prestone and have no cooling problems. I live at the beach and drive my stage 2 Jetta 2.5L pretty hard.
Pros: no cooling problems
Vehicle:
Volkswagen Jetta
I use the purple peak G13 in mine - from autozone. Its actually more pinkish when it pours. Made sure to flush with distilled water before adding the new coolant just in case but its been fine in my car. Don’t overthink it!
Pros: been fine in my car
Vehicle:
Volkswagen Jetta
If you are going to use Prestone brand, then you'd want Violet color.

You will probably be fine running the Peak stuff if you have to, but I seem to recall a few years ago I was able to purchase Pentosin/Pentofrost from Advance Auto Parts. That was a brand that I saw often on VW parts sites and it meets the standards for using it in the MKIV VW cooling systems, so I went with that.
Pros: meets VW standards
Vehicle:
Volkswagen Jetta
Buy 5L Vaico brand G13. Flush the system several times with distilled water. Then drain and purge with compressed air. Disconnect the heater core lines. Then pour in all 5L of pure antifreeze, and top off with distilled water.
Pros: acceptable mixture
Vehicle:
Volkswagen Jetta
Use the specified coolant I would use the specified coolant for the vehicle in which you drive and always use distilled/deionized water foreign or domestic! The cuts down on deposits and electrolysis from corrosion from using tap/ground water and or the incorrect coolant.
Pros: cuts down on deposits
Cons: incorrect coolant
Vehicle:
Volkswagen Jetta
When I bought my Jetta it was filled with Prestone. One time the fan switch crapped out on me so while replacing it I did a coolant flush and decided to use G12. About 2 weeks later the car started overheating like mad.
Cons: car started overheating
