Haz77 0 Report post Posted February 24, 2013 Hi, 2000 E39, Had the message up for a couple of weeks now, got the garage to check it out during the service and they said the pads are fine but one of the sensors looks like the wire might have broken or be damaged, he did say that he replaced 2 on a car he had once & it didnt clear the warning though. Question is, if I simply cut the "broken looking wire" & join it should it clear the warning & prove the fault? Im guessing the other 3 sensors will still warn if the pads are low, the warning does come and go so it obviously doent need to be reset. Im "keen" to identify the fault rather than just throw new sensors at it, they quoted about $100 each. Quote Share this post Link to post Share on other sites

hotwire 352 Report post Posted February 24, 2013 The circuit is a closed loop through two sensors - L/H front & R/H rear A break in the circuit will bring the light on. $100 for a sensor, havent checked recently but I am sure they are nowhere near that. If a broken wire - then simple to fix Quote Share this post Link to post Share on other sites
Haz77 0 Report post Posted February 25, 2013 So,,, Need to know if this message is only sent by the brake pad sensor or if the ABS sensor runs the same warning? Cheers. Quote Share this post Link to post Share on other sites

Nup, separate circuits/ sensors. ABS sensors are on each wheel. Brake pad wear sensors are only on L/F & R/R & bring up the brake lining W/lamp.

Haz77 0 Report post Posted February 25, 2013 Cheers guys, Did see that price & have been talking to Paul thats why I needed to know if the prob could be the pad or Abs sensor. The garage said they he thought that was about what he had paid for his a few years back, maybe he got them from a BMW dealer. Quote Share this post Link to post Share on other sites
