Hi, I was just about to take the car for an MOT, and to my horror, the red brake pressure warning light has come on - (!) the one in between the hand brake and the ABS warning light. The light stays on continuously, and does not flash. I looked in the owners handbook, and it advises to check brake fluid and power steering fluid reservoirs, which I have done, and both are as full as they should be. I have not checked brake parts, but I was hoping someone could shed some light on this subject, and help me out. |

Brake pressure switches - the ones above the sphere or "bomb". Carlos identified these as having failed yesterday
Also declared dead: my original front suspension (and you know what the implications of that are!), both front tyres....and the coolant expansion tank sensor Edited by Horsetan |

Did you have the red light on like me? If so im going to test those - cheers Ivan.
I believe there are 2 of them, that look pretty identical. Edited by phb10186 |

I traced my red light to a short-circuit behind the instrument display. The light went off if you shook the dashboard! Clearly there was a loose wire touching....
Yes. They can leak and fail, so I have to change mine. (I'll also be changing my coolant expansion tank and tank level sensor, as these have had it now.) |

They're different, items two and three, and they're about twenty-five quid or so each http://www.realoem.com/bmw/showparts.do?model=5382&mospi d=47199&btnr=34_0271&hg=34&fg=25 HTH, Sharkfan |
