No way for 2800km, unless you go to a track every weekend.
My dealer said F30 has some issue with the system. If you take your car to the dealership, they will probably just reset the system.
I had a good amount of fun during 1st year with F30 with a lot of caynon driving, and my pads got replaced at the dealership at 8800 miles. For normal driving, they should last at least 20,000 miles.
