I’m running 110k miles in my M40 X3. There was a coolant issue but other than that it’s been an excellent engine.
I use BMW coolant cause it's similar in price, so why not. Actuall,y a little cheaper cause my dealer does discounts
By “air intake reservoir tank”, I assume you mean it’s the coolant tank for the water-air charge cooler. We need to know what car to tell if the coolant is suitable. That “G30” on the front is the important bit.
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 always use Prestone concentrate and then dilute it down to a 40/60 coolant to water ratio.
Prestone is designed to be compatible with the Toyota Red coolant, which is also POAT. Should be fine.
I’ve had no issues with Prestone Platinum in my MK6 CJAA TDI. It’s been in for 4 year 65k mi.
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.
330i, coolant repairs.
