Have a 2014 cooper s and going to do brake fluid flush. Do you guys buy the fluid from dealer? What's the OEM part number? Or do you buy some other brands online? How much is usually the cost+labor for brake fluid flush?

Also, the coolant level is below LOW (engine is cold). Is this normal? Do I need to just top it off or I should ask the dealer for a checkup?

 

You can buy it on line, no need to go to Mini store.
You need DOT 4 or DOT 5.1 !
It takes arround one hour labor.
The coolant level is always arround low.
It's the same on my car and lots others
