Change transfer case fluid, reset needed by BMW?
 
I changed my transfer case fluid on my 2004 X3 but the fault light keeps on coming on once in a while. It goes away for a while once I turn off the engine and restart it. But am I suppose to reset the transfer case/computer via the dealer?

Thanks in advance!

Yes, BMW call for a reset when the fluid is changed. If not the dealer, then someone with the appropriate computer tool.

Gee3 10-20-2012 01:20 AM

Thanks JCL!

Anyone in San Francisco have the reset tool so I don't have to go to the dealer? I'll buy you the beer and lunch! :)

Gee3 10-20-2012 10:04 PM

How much are dealers and independent mechanics charging for the computer reset? I called my local dealer and they said $180! WTH?!?

JCL 10-23-2012 12:04 AM

I don't know, but I would have hoped more like $100

Gee3 10-25-2012 10:21 PM

Maybe I'll see if an independent shop can do it.

that light is an indication of an error in the system, the fluid wear values does not cause the light to come on.

I changed my transfer case oil around five months ago and has not reset anything. I hope it is not destroying anything. I thought as long as the oil is new the transfer case should be ok, but I might be wrong.

Also, the reset does not turn on any warning lights. It only activates an OBD code that say something about transfer case oil having excessive friction. I am sorry I cannot remember the exact wording now.

To be honest, I cannot imagine how anyone would know about this if they did not have a scanning device. I read mine because I have the Bavarian Technic device. I was resetting after an oil change and I noticed the warning. It even said the error would not cause a warning light to come on.

So, the question is: if the reset was so necessary, why doesn't it turn on a check engine light? What does the reset to anyway? Isn't the transfer case a stationary set of gears that transfers the vertical rotation to a horizontal one? What does the computer reset exactly?

JCL 11-15-2012 01:40 AM

I believe there are two different items that are affected by a reset, or whatever it is called.

The fluid condition monitor is supposed to know that there is new fluid in there, so it will know when the fluid is out of spec.

The transfer case just splits the power front and rear. However, you have x-drive, with a variable torque split. The x drive clutch packs have an actuator that applies pressure to shift torque front/rear. There was a reset procedure I read based on the actuator measuring its travel, so it knew where the engagement point was for the clutches. This is the one I would worry more about, as clutches not fully engaged could wear quickly.

It doesn't turn a light on because the driver is not supposed to change the fluid. The service manual describes the procedure.

Is there a service manual out for the X3?

JCL 11-16-2012 11:46 PM

Nothing like the Bentley manual that I am aware of, but there may be something.

Look up the factory TIS if you like.

Here is the page for the transfer case oil change.

BMW TIS - 00 11 572 Changing oil in transfer box (ATC 400/500)

Whole thing here:

BMW TIS Online • 3' E83

vince59it 11-21-2012 05:04 AM

the oil of the transfer case DOES not send any signal. The lamp on the board means a problem in the TC

rdc8118 11-21-2012 11:26 AM

Vince, nice avatar :wow:
I read through the BMW TIS that JCL posted (thanks). As per the TIS, can the self-adapting wear values in the transfer box control unit be deleted using INPA or GT1 required? I moved from an e39 to an 08 X3 3.0 so I'm not sure what software works on the X3.

I went severaltimes with the INPA and GT! but never seen something like that for the ATC.

OT:thank you ;-))

There is a transfer case Reset? I have changed my transfer case twice as preventative maintenance and never knew that there is a reset procedure...

It's part of the DIS software; there's a service function which allows you to say that the transfer case oil has been changed.

Just curious...

For the E53 X5, the transfer case is different between 2001-2003 (ATF) and 2004-2006 (Special BMW fluid).

Does anyone know if E83 X3 transfer case fluid varies from which year to which year?

JCL 12-24-2014 12:32 PM

The E83 used the ATC 400 transfer case (with x drive) from 2003 until 2010. There was a part number change during production. Same oil is listed for all years.

cn90 12-24-2014 03:57 PM

Thanks,

I currently own a 2006 X5, great vehicle.

Question for the X3, is there a year that is better than other year (such as transfer case issues etc. etc.), should I decide to buy an X3 in the future?

Within the E83 production (since this is the E83 forum, and I presume that the 2010+ F25 X3 isn't in the comparison) I would look for a 2007-2010 X3, which was the facelifted version, with the 3.0si (260 hp) engine. Up to 2006 there was a lower power M54 six (same 225 hp as the early X5) but the later ones are worth looking for IMO. All have the same awd system. And manual transmissions beat automatics every day and twice on Sunday. But then I'm biased.

Earlier X3s had a harsher ride, and some automatics had an issue with rough shifting.

This might be helpful for your E83 guys, I just finished uploading a new video to showcase how to drain and flush the transfercase (transfer case) for a 2005 E53 X5. At the end, I even show how to use GT1 / DIS to perform the adaptions reset.

Hello, I recently replaced all fluids, front and rear diff, transfer gear and transmission oil. No reset needed. Something​ else is going on. There's no need to reset computer for diff oil change.

Badasblkbmwx5 06-05-2017 10:34 PM

This was done on my 2007 X3 3.0 motor.

JCL 06-24-2017 04:14 AM

I have a 2007 X3 3.0si. The BMW service manual says:

Quote:

00 11 572
Changing oil in transfer box (ATC 400/500)
Important!
When changing the gear oil, it is necessary to delete the self-
adapting wear values in the transfer box control unit.
Refer to Service functions.
Use only the approved transmission fluid.
Failure to comply with this requirement will result in serious
damage to the transfer box!
Nothing to do for the diffs, but the transfer case, yes. I would use the word "may" and not "will" for resulting serious damage. Understanding how the transfer case will have different clutch engagement for the front/rear torque split depending on the transfer case fluid properties, it only makes sense to delete the adaptations that are stored for the old fluid.

kmm111 10-07-2017 07:21 AM

The transfer case adaption can be reset using Autel maxisys scan tool. while not "cheap", many independent shops have these now. It's burried under the "maintence" section.

Badasblkbmwx5 11-08-2017 11:06 PM

still no issues/no computer reset
 
It's been 6 months and over 6k miles since I changed transfer case fluid/front and rear diff and transmission fluid. I have had no issues, no warning lights on dash and I did not reset anything. 130k miles still running strong

Xm4n 01-09-2018 06:55 PM

Hello all, also note if you have D1S you can activate this reset adaptation feature.

80stech 01-09-2018 08:08 PM

I don't think you necessarily need to reset adaptations if only changing fluid since your not changing any clearances the adaptation will adjust the little bit it might need to for the new fluid. The fluid wear code will not turn on a warning light as mentioned previuosly, and will need to be reset(if it bothers you) as the processor can not tell if new fluid has been installed.

joebrowntech 02-20-2018 04:48 AM

For the best results with your BMW, I would suggest you to consult the user manual for your vehicle. This contains all the information regarding transfer case fluid.
But if you do not contain the user manual for your vehicle, get a copy of it online from manuals.co, which offers all kinds of car user manual absolutely free of cost.
