RealOem bmw coolant mixed with RealOem audi coolant

[Germancarsrule]

Hello, a while ago my coolant was pretty low so i filled the expansion tank with audi coolant since everything was closed and had to get home. Since both of themseem to be hoat. Is it fine or should i flush it ? The / is very small. Ive filled from a bit of the bottom of the expansion tank to between min max. Car is a 2012 bmw 335 n55

Thanks!

If your BMW has the blue coolant then it is compatible with the old Volkswagen blue coolant. They are both G11. If you used pink VW coolant then that might not have been a great idea. Here is a compatibility chart that shows what the G11 (your OEM BMW coolant) is compatible with regarding the modern VW coolants.

We don't know which coolant you used so check your bottle and see if you are lucky and have a compatible chemistry.

If only a small amount was added, I'd probably have just driven home with the expansion tank low.

Which type of audi coolant? I've seen expansion tanks be empty yet the car still runs fine without any overheating. Did you get a message on your dash? i'd've just stopped at a store to get a jug of distilled water and add half of what's needed and then buy the concentrate later and add the other half in.
