Antifreeze PEAK or OEM Volkswagen

I use Peak red concentrate, no probs.

I put purple in my 2015.

I'm the kind of person who uses 100% OEM whenever possible, but I wasn't actually able to find OEM G13. Not sure who the OEM even is.

The purple "Peak" brand coolant in your image is the only kind I was able to find. I've got about 10,000 miles on it and it's been just fine so far.

I’ve used that stuff, absolutely no issues.

I run it and haven't had any problems, just topped it off and kept rolling.

The Peak coolant that is the correct color for your year, i.e. pink for the MkIV, is fine. I have been using it for several years with no problems.

I ran the euro Peak without issue for about a year but I was bleeding coolant and in desperate need of the cooling system overhaul.

My car is currently filled with the Peak Euro Blue stuff, works fine, identical to the OE BMW formula anyway

I personally use Peak brand coolant, and I've never had an issue for 100K+ miles.

Even though most will say to stick with G12/G13, I think that is where that "sand" comes from. I decided last year to completely drain the system - including engine block - and converted to Peak antifreeze. I have not had any problems since.

I got the light this morning on the wife's JSW. So I checked out the situation. Sure enough seriously low coolant, like well below minimum fill line. Only 7000 miles. Took it to the dealership to have it topped off.
