How do you check the brake fluid level?
So my DSC light came on out of the blue tonight. No other warning lights were illuminated and no codes came up with my Peake reader. A quick search suggests wheel ABS sensors, fuses, and low brake fluid level to start.
Fuse 17 was a bit out, and when I pushed it back in the light went out. So I think that is the cause. However, my original brakes (pads and rotors) are at 57K miles so I thought I'd check the brake fluid level anyway (I should point out I had a brake flush a few years ag0 as part of the BMW maintenance program, then had Inspection II in January 2008). So the manual tells me the reservoir is under the driver's side air cabin filter housing, but does not state how to access it. I found many posts alluding to taking out the cabin filter housing but none that actually describe how to do it (maybe I missed the posts, but I did try).
So, just out of curiosity, how does one actually check the brake fluid level?
Thanks in advance.
