Can't get rid of Brake Service light - BMW 3-Series (E90 E92) Forum

skim7x · 01-22-2012, 01:16 PM

So about 2 weeks ago I had some AR Design Cattless DP's installed on my car along with BMS DP Fix (v3) set at 6 o'clock position. Haven't had any codes or anything until about 4 days ago when the brake service light came on. I took the car to BMW and they said the brakes were fine and the code was a faulty code. Now, this is the 3rd time I've had the brake service light come on inappropriately. However, this time BMW says that they could not clear it... they tried multiple times but were unsuccessful.

Anyone have this problem? Maybe the BMS DP Fix is set too strong (although I haven't seen any other reports of this problem on other DP Fix threads).

My other performance mods are: Dinan Stg 2, AMS FMIC, AFe drop in filter, AR Design Cattless DP's

Thanks all!

Maybe your brake sensors needs to be replaced. I think there are two. One for the front And the other in the back.

Hey, been a long time! I believe they checked the sensors at the BMW dealership... the tech told me they were fine...

bimmertt · 01-22-2012, 02:29 PM

Since you had the dps and dp fix running fine for a little over a week, I'd be inclined to think the sensors are now bad.

I'd check the brakes myself to see if the pads are low. The sensors are one time use so if the pad wears down enough to the point the sensors are hit, that light will stay on no matter what until you get new pads/sensors.

I have the same problem, but my light came on after I tried rsetting the CBS viz the BT tool.

What's the CBS? Central Braking System? lol...

So you guys find a fix for this, or your Brake light is still on? It's not the fact that it's on that bothers me as much as now I won't know when my brakes actually need changing =P Guess I can do it old-school style and check at 6 month intervals with oil change or something...

I'm replacing the sensors with my new pads soon so we'll see then if that helps.

badass335 · 01-22-2012, 02:37 PM

You'll need to get your cars flashed with the latest software to get rid of this. On the new software, they remove this monitoring. I had it on and off for a year and BMW did the brakes, and replaced sensors about 5 times within the year. I'd check with the BT tool and the sensor would read 600000km's overdue etc. It was a malfunction. Pain in the ass!
Replacing the sensor is a temporary fix. Resolves it but will come back randomly. Say you drive through a big puddle of water and it hits the sensors just right etc..

Yeah, the BMW Dealership actually mentioned that one of the possibilities was that the flash I had on my car was a "cheap flash." LOL... I have Dinan... not only is it the most expensive flash, but I don't think anyone would argue that the software is in any way half-assed... but anyways, yeah that's another idea... try to get the most updated version of the Dinan flash / BMW software. Maybe I'll try to get the newest flash soon...

I've been on the fence between getting the BT tool or just getting the Cobb AP so I can start reading my own codes. I'm out of warranty now, so a lot of these little warnings going off I'll need to fix myself and then i'll need to be able to clear the errors with some sort of tool... with Cobb AP I'd get a nice little boost in power too, with the Cobb Stage 2 + FMIC =P

Brey335i · 01-22-2012, 02:48 PM

The COBB AP is not able to clear that type of code. That's why I still have my BT

Keep in mind, though the BT Tool was able to read this, it could not reset the codes.

So neither the Cobb AP nor the BT Tool are able to clear codes? You need another device in order to clear the code?

scottp999 · 01-22-2012, 04:03 PM

I've used the BT tool to reset the conditioned based service warnings more than once for the brakes, and other items. Works like a charm. http://wiki.bavariantechnic.com/index.php?title=CBS

I never used the reset. I just went in to adjust values and bumped up the percentage remaining.

805beemer · 01-22-2012, 04:07 PM

you can clear and read codes with the cobb ap, doesn't even need to be married to the car. I think brey is just saying that it won't clear your particular code for some reason.

Wont work if the sensor is faulty. I tried many times. You can adjust the condition based service but in the OP's case, he's mentioning that BMW has issues resetting codes so most likely faulty sensor which can't be resolved with BT as the condition is still present.

Randomaccess335 · 01-22-2012, 07:20 PM

What's on your dash? Mine was car on lift in red( saw it when started car and turning car off) and the word brake also in red on all the time.
I finally figured how tow to clear it

Yeah that's exactly what I have... how did you clear it?? Any idea what it was caused by?

Will this happen to aftermarket brakes?

Since they don't have sensors...

You can force/wire the circuit together so the circuit will never be broken.

idrift4wd · 01-23-2012, 02:25 AM

Solution(if your brakes are fine)

put your car in accessory mode and wait till the service symbol dissapears hold your odo button and a symbol should come up let go and scroll through the system and reset your brakes from there.

vase330 · 01-23-2012, 09:54 AM

You mean the odometer reset button right? Wow that sounds easy. Actually I think his sensors are bad. I have had the issue and dealer replaced the rear brakes even though they weren't that won, and problem solved. I also had a nasty screeching issue that happened only with the car driving not on level surfaces and that went away too. They told me it was just the sensors.
