2009 MCS

111000 miles

I replaced the front pads and bought an AutoZone brake pad wear sensor. After installing, the trouble light for worn pads still comes on. I researched this on the web, and see that Pelican Parts says that 2009 has a two stage wear sensor. A new sensor should read 5 ohms resistance. AZ sensor reads dead short. I bought one an Amazon, out of the bag, it reads dead short. I went back to AZ and tested another one from the shelf, dead short.

I cut the old sensor off and wire nutted the leads together, light is still on. I put a 5 ohm resistor in line with the old plug, light is still on.

short of buying and trying a BMW sensor, can anyone point me in the right direction?


I do have a code scanner with the ability to erase codes. I have tried to erase this one, but it just keeps coming back.


I do have the Bently Bible, but it gives no useful information on this issue.

 

Did you try resetting the service indicator? If my old notes are correct I think this is the procedure that worked on my 2012. Not sure if it also works on a 2009.

• Start the ignition and wait for the service info to go out.
• Then press and hold the right button.
• The first service item should appear after 10s on the display.
• Release the odo-reset button and hold the button on the light stalk
• Now "reset?" should appear below the service item
• To reset, press AND keep the indicator stalk button held once more
• During this time a clock will appear. Some seconds later the procedure is complete
• Repeat for all service items you want to reset.

There's another slightly different procedure here but this didn't work for me:

OBD2 will not clear the alarm i tried to reset when i changed all the brake in my car 2008 clubman S.
Gubi is right follow his direction by using the car reset button.

 

I will try it out and let you all know. Thank you.

 

Gubi,
I tried your suggestion. It worked! Thank you for helping out. I am still confused about the testing procedure on Pelican parts that says I should be able to test the sensor at 5 ohms. Bently Publishers had a procedure that said the same 5 ohms should be read on a new sensor. I tested my meter with known resistors to make sure it was accurate, but only ever had test results of dead short. Maybe I missed something else.

Good news is, the light cleared. Now to go find out where my antifreeze is leaking from. :-(
