My red brkae light comes on occasionally while driving.
The ABS light also comes on at times, but seems to go out when I restart vehicle . It has been on for two days now and I must manually shift vehicle for it to shift into 5th gear. The weather seems to make the lights come on, when it rains in the past.
I did change shift selector switch for a different problem when it rained and it fixed that problem 100%. The is something new.
1997 528i
Any help will be appreciated,
John |

I also have a 1997 528i with the same problems except I have to shift it manually from first all the way through and my lights stay on. I was told to check the wiring in the rear passenger wheel well. I have been driving my car this way for about a year now. I have the actual program that BMW currently uses to diagnose and repair and everything it states is to check and repair any wiring then reprogram it. Of course I don't have the equipment to reprogram so it looks like it needs to go to a shop to be fixed either way you look at it. |

According to your owner's manual, it could be that the brake pads are worn down, OR the brake fluid is low.
I have observed that, in wet weather, the wear sensors can sometimes show a false indication. If your pads are not worn down, try replacing the sensors. _________________

I'm not sure if you fixed this problem or not, but I finally figured out what it is. In the drivers side front wheel well above the strut there is a rectangle box. The wires from there to a sensor behind the wheel were broken. I stripped the wire back and resoldered them. There is a red wire and a yellow wire. After I put it all back together my ABS, traction control and brake lights all went out and the car is now shifting automatically! My wires were broken close to the sensor so I don't expect it to hold long. I am looking for a new sensor for it. I hope this info helps.[size=18][/size] |
