488 New owner hello and some questions about chirping (sorry) and manetinno display and others

Hello all,

Been lurking on this chat for a few weeks, Recently acquired a 2017 488 GTB with 6500 miles. Non-cpo. Absolutely love the car! Some questions and sorry for reduncy. Just know before anyone flames me, I HAVE searched extensively on these topics but can't seem to get a good answer.

1) Chirp while coasting and sometimes even accelerating: absoultey worst part of the car! Can't seem to find a definitive answer. Top searches have yielded 1) pre fill brakes encountering dirty rotors, 2) that's just the nature of ferrari brakes and can be remedied with pagid (which doesn't make sense because it ONLY comes from the driver side and most pronounced when coasting and turning left) 3) some vent tube on the driver side wheel well that's rubbing. Have an appt with the dealer for service (oil, fluid flushes etc) in a couple of weeks and will ask them as well.

2) what is the signficance of the manitenno status screen in VDA when you're driving? What do the colors and bar graphs (1-3 little bars) idicate for F1 trac, SCM, E-diff? Do certain colors and less bars been they need service or they're "less warmed up". I don't mean the page that says "warm" "go" etc. It's the page after that displays all the functions.

3) What coolant do you buy? Went down that rabbit hole and still couldn't get a good answer. G30? When you go to autozone or any other online auto retailer and put your cars info in, it recommends Peak European Formula coolant. I use the same in my 911 turbo.

Thanks all and happy to be a Ferrari owner!
