DSC Internal Sensor?

WOW, they sure went up since last year! I just paid $487 + tax for the same part for my 2005 X3! And that was with my BMWCCA discount!

Tighten the screw properly or the box will warp.

Congradulations. I am glad you got it all done. So no more errors? Scan and reset with GT1, I am sure the fault will still be there.

Also a suggestion for anyone reading. This tool has saved my knuckles countless times. I recommend everyone have at least the straight one. I have ones that are bent also. A screw gun driver will fit, and make an extension for you. You can basically put any bit into it and you have a ratchet drive screw driver.

I updated the first post with the results. After replacing the sensor the warning light and SLS Inactive message both went away.

In GT1 CANbus error (SLS inactive) was not present anywhere. The DSC sensor error showed up in the first screen after a Short Test - but DSC module does not show having an error on the screen where you delete faults.

If I run a test plan on the DSC error it proceeds to read the DSC module and says no fault read. If you run the short test, DSC module does NOT show an "X" indicating a problem in that module.

I will try and clear it by turning/on off between deletes and/or try to find something in the function mode. Maybe its one of those errors that stay because its a clone GT1 - like that stupid BD fault (Brake Force distribution) that always shows but I cannot clear it and I have no way of clearing or even have a test plan.

There's a screen where it will show readings of the DSC sensor (rotation-rate) but I couldn't remember where I found it. I'll go back and look some other time.

I was to eager to get done and stop from being eaten alive by the mosquitos!

BTW .. you can bet that I did NOT completely tighten the hard to get to screw. I just threaded it in enough to stay in place and fuggetboutit!

Fugghetaboutit. LOL. You know there is a sign when entering Brooklyn from NYC, it says, Welcome to Brooklyn, Fugghetaboutit. lol.

The highlight indicates to me that replacing the yaw sensor did not remove EBV fault discussed in the forum post https://xoutpost.com/bmw-sav-forums/...ml#post1155712. Right?

Tried pressing the DSC button on the console to turn the DSC light off - no change.

Pulled, checked and re-installed fuses in the back and glove compartment - no change.

BTW ... there's a 30amp fuse in the back panel, looking at the panel its the last one all the way to the right, that only has one connector on the female side - unlike the others which have two. I think I found another one IIRC that was marked "trailer socket" and it also had one connector in the fuse block. Weird.

Anyways, scanned it with the GT1. Got a "5F0C DSC sensor, internal" fault in memory that was not selectable or deletable.


Went through the Test plan and got these screens.


Based on those screens, I interpret it as the internal sensor fault was found in the DSC module not a separate sensor that could be replaced.

So, before I buy a DSC module I want to see what the forum has to say.

The external sensors are a Brake Pressure sensor, (Four) Wheel Speed sensors, (Two) Rotation Rate sensors, and a Steering Angle sensor. There's also a DSC Hydraulic unit but it doesn't seem to be related to any of these at first glance.

Maybe I should disconnect the battery for about 1hr and see if that helps.

SOLUTION:
Replace Rotation Rate (yaw) sensor under the center console. Old sensor (discontinued) on the left and made in Germany. New sensor on the right and made in Hungary. After replacement, the DSC/xDrive (4x4) light and SLS Inactive message went away. I did not have to code/program anything.

I know this is old thread but I hope you guys can give more input above issue. 2005 X5 3.0, have the same issue as above. I replaced the rotation rate sensor and wheel angle sensor, the fault still
there. I read few thread about to calibrate the wheel angle sensor after installing a new. By the way, I don't have calibration tools and the dealer charging $150.00 to calibrate. I appreciate for all input.

Update!

Was able to remove the ABS module with relative ease and sent it off to MyAirbags.com to repair the module. The removal was made easy by removing the headlight and the coolant pump that is sitting right in front of the module. Removed with a T20 screwdriver and ratchets.

Sent to MyAirbags.com and they repaired the module and sent it back within a week (not the 24 hours they claimed). Still happy with the return time and overall results.

Upon installation of the module, the lights still came up. I drove the car for a bit and less than a quarter mile the lights all went away and i haven't had the intermittent speedo/lights issue for the last few days; rejoice!!

I am still getting the SLS Inactive light but hoping my indy shop can scan and see what it is. If it's the ride height sensor module, i am going to just keep driving it as i replaced both airbags and ride height sensors in August and i know the system is fine.

All in all very happy with the results and thankful i have XOutpost for all the info and support; thanks y'all!!

Nice one AJ
Looks like that was the main problem then.
I have every confidence you will get rid the SLS problem now.
It won't go away by itself - let us know which codes it is/was when you have it diagnosed eh!
