Brake change...light not resting
 
I change my brake pad and I have tried two different sensors and I can't get the light to rest...I have also tried going into the car settings and rest it there....still did not rest.....I have a 2004 745LI

Do anyone have any idea what should I try next?

You need to reset your service interval thru hidden menu in KOMBI

I also changed my rear brake pads & tried to reset the service interval thru the hidden menu but the red car warning light will not turn off & now when going to the I-Drive menu it says my rear pads are -16,000 over due. Just before I got the pads changed the I-Drive menu said -8000 over due.

When I did the reset in the hidden menu the last step highlighted reset & when I pushed the button it can up OK or something like that. I also reset the engine oil interval & it reset it to 24,000 kilometers. I scrolled through the I-Drive to see if there was any other service that was due but everything was green other then the rear breaks which is staying red along with the red car warning light.

Any suggestion's on how to solve this problem would be appreciated.

When you changed the pads, was their damage to the pad wear sensor?

my mechanic said he did not think there was any damage to the wear sensor.

you need a new sensor.

I will order & replace the sensor & will give update once I have installed it. Where would be the best place to order it? Thanks

You have 2 sensors on your car. 1 on the left (drivers side) front and one on the right rear. You can change these easily enough by jacking up the car on the jack pad and remove just the wheel that you are replacing the sensor on. No need to remove the caliper, pads, or rotors.

Autozone $20.00

Yep. With bad sensor you'r not able to reset service interval. Just measure resistace to check the sensor-continuity test or temporary bridge the sensor to see, if you can reset interval

OK, the sensor arrived yesterday & I installed it today & reset the rear brake service interval setting & the red light turned off & the interval now shows 31 tmls.

I noticed when scrolling through the service interval list that the front brake interval reads 43 tmls & I reset it a few months ago.

Why would the front interval read 43 tmls & the rear interval read 31 tmls when I just reset the rear today but reset the front sensor months ago?

CBS interval should be 32000 miles for rear and 25000 miles for front brake pads

That makes sense to me. I wonder why my CBS interval for the front pads is reading 43,000 mls? Not only is 43,000 much higher then the maximum number, I reset the front CBC months ago. I also checked in the I-Drive menu & it also reads 43,000 for the front?

While the rear is not so far off, it should be reading 32,000 not 31,000 since I changed it yesterday & have not driven the car?

If You have diagnostic software, then You can correct it

I do have INPA software installed on a laptop but have not used it for anything yet. Is that the software that would be needed for this & would you be able to lead me through the process of correcting this problem? I would be most grateful.

inspi 11-18-2012 12:30 AM

Hi, I know You can use INPA to reset service interval(under Body-Instrument cluster), but I don't know if You can correct data with INPA-never tried. I always used DIS software. In DIS You go to: Diagnosis - Function Selection - Service Functions - Maintenance - CBS Correction, Vehicle Data and change the value
