A4 Peak Euro coolant - is it safe?

Hey all - I got this yesterday for cheap and I'd like to make sure this is safe to be used in our cars. It does say 1996-2007 Audi and it's got the same specifications as G12 in regards to being phosphate-free, silicate-free, and compatible with aluminum engines and radiators.

I'm planning on doing a coolant change early next year, so I'd like to use this if it's fully compatible with the 1.8T.

Thanks in advance!

I stick with pentosin but I'm sure it'll be fine as long as it's g12+

That's what I've been using in my AEB.

It should be fine. It is fully compatible with the original G12. The only issue you could have is if someone flushed the coolant before and replaced it with an incompatible coolant.

In that case, just make sure to also flush the heater core.

Thanks! That's what I had to do right after I got it about 1.5 years ago lol previous owner had the cheapest coolant he could get (think "normal" neon green stuff from AliExpress).

Yes it's fine for B5s. It's all I can find around here almost everybody stopped carrying pentofrost concentrate. I've been using it for several b5s for years. Totally fine
