Got in my 07 335i today and got these warnings...
Doing some searches and found that it may be brake pads/fluid level. Is that accurate? How much is a brake job?
I bought the car 6 mo ago with new (appearing) rear rotors and the fronts looked worn, but not worn out. The front rotors do have a bit of lip from the pads wearing them down.
Since it's Saturday, is it safe to drive until I can get it in?

I've also been getting random yellow engine light that I attribute to the JB+ being installed (did the bypass and it comes up less often, but still comes on). Is there any correlation?

Thanks in advance for the help!
