Antifreeze Pentosin or OEM BMW

I believe Pentosin Pentofrost A3 is equivalent and it's also $19 from Advance Auto. I have both at home because the Pentosin is equivalent to Subaru coolant as well.

I'm almost positive that VW uses Pentosin at the factory- I think the G12/G13 is the same stuff as the Pentofrost SF/Pentofrost E.

I use it in my Audi, VW and KTM Adventure without any problems.

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.

Do not, under any circumstances, mix generic auto store coolant with G12/13. If you are low, top it up with water - distilled preferably.

O'reilly around me carries the correct G12. Brand is Pentosin.

this is the proper coolant, and the best option out there....Ive used Pentosin G11 blue forever....

VW G12 and Pentosin G001200 are the same thing, both are pink/violet in color, phostphate, nitrite, and amine free. You should not mix cheapy prestone / o'reilys with the G12, it may turn the coolant to a sludgy substance and clog the system. Basically solidifies when mixed with other coolants. Also may build up rust or other small deposits through your cooling system.

Regarding genuine VW antifreeze and generic...from what I understand, anitfreeze like Prestone is phosphate free but the real VW antifreeze (Pentosin) also has protectants for the plastic parts of the system, etc. The genuine stuff really isn't that expensive from the dealer.
