I use peak violet european formula in my mk8 R.
I use Peak, and I think they recommend the violet stuff.
I just use peak pink made for Alfa Romeo and European vehicles overall and it works fine!
I use Prestone 50/50 HOAT compatible in my 2012 JK and it works great. I like to do it every 3 yrs or so.
Prestone Max Violet is ok to use--it meets G12++ or TL774G which is fine to use with the G12evo in your car already.
I've mixed Peak Violet in with the OEM G12+. My car ran normal for several thousand miles like that.
I always use Prestone concentrate and then dilute it down to a 40/60 coolant to water ratio.
coolant is always best. I would get rid of the green coolant, flush it all out and replace with something better. I use Peak Final Charge in everything.
Most likely answer is he used one similar to PRESTONE which they do have one thats for all makes and models, it is a universal coolant including European models.
I paid for a coolant flush and the mechanic put back in peak 50/50. The orange kind not the gold. At least its not mixing with the HOAT but im pissed
