I have a 2002 X5 4.4i. The red brake warning light came on yesterday. It only says "brake" in red. I checked this forum and it stated to check the fluid level in the reservior. I can't find the thing to save my life. I know that it is supposed to be on the drivers side under the microfilter buy Im not seeing it. Maybe im retarded. Also, my service engine soon light came on today. Any help would be much appreciated.
