Have a water cooled 279cc Scooter, will this help a small leak that cant be found?

I used this in a semi truck radiator and it worked great

How many bottles do you need for a 11 gallon cooling system

I put 4 bottles in 10 gal system which was plenty

Will this be suitable for a 2017 bmw 330i?

Yes, I had a temp sensor on my 545 bmw and it sealed it up in under a week was not a leak more like a seep, also theses v8 engines tend to leak at the coolant pipe that pass through the block . used it to maintain the seals also to stop possible future leaks. Dan

Will this work for the coolant transfer pipe?

No. If the coolant transfer pipe has a pin hole in it this will not work. The coolant transfer pipe will need to be replaced.
