Transfer Case Actuator Motor issues

Hi Guys,


2007 BMW X3 161k miles

I had the 4x4, Brake and ABS lights come on last Friday. I've replaced the the transfer case actuator gear about 50k miles ago when the car displayed these lights and was driving poorly at low speeds.

Today I pulled the gear again and it looked a little worn but not nearly as bad as it had when I replaced it 50k miles ago. I rotated the gear so the worm would be positioned on fresh teeth, added some grease and reinstalled.

I took the car for a spin and the lights came back on, now with the addition of the DSC light.

I pulled the following codes:

- Fault: Clutch position unknown -. Transfer Case Ec
- Code: 005F39

- Fault: wear oil
- Code: 0054C6
- Fault: Actuator errors or increased demand for electricity clutch
- Code: 005462


I have had the wear oil code for a long time. I replaced the transfercase oil about 50k miles too but don't have the equipment to reset the adaptations.


Do you think the actuator motor is shot? I don't want to spend that kind of money just guessing at the issue.

Also, not sure if this is coincidence or not but this issue arose the day after I had my snow tires swapped out for my all season tires..

Thanks!

This transfer case actuator resistor might be worth a try too?

https://www.ecstuning.com/b-genuine-...r/27107557345/

If the resistor was bad that might be what is triggering the following fault:

- Fault: Actuator errors or increased demand for electricity clutch
- Code: 005462

I just disconnected the VTG harness to the servomotor, suggested by Bentley Repair Manual, and the issue is still there. Car shakes and requires more power applied during slow speed turning.

Just came across:

http://www.bimmerfest.com/forums/showthread.php?t=846517&page=3

Very similar to what I've experienced. I've got a new servomotor coming in the mail tomorrow. I wish I had read about the Land Rover servo earlier but I think I'll stick with the $399 one being delivered tomorrow rather than reorder and delay myself even more.

I'll let you guys know if the new servomotor fixes the issue. I realize I'm speaking to nobody but someone might find this helpful someday lol.

That's not encouraging

Do you think based on my codes, or experience, that it's actually the t-case and not just the servo? I will try to rotate the input shaft when I get home and see if it rotates freely.

codes are not perfect indicator

>the codes only put you in a ball park of possibilities

>best to follow what DMF did and check rotation etc

Fingers crossed

Well I got home and my new transfer case actuator was waiting at the door for me.

https://www.ecstuning.com/b-bosch-pa...107566296~bos/

I got under the car and tried to wiggle the input splines and it had no play at all.

Since I didn't have a wiggly shaft I proceeded to remove the resistor from my existing actuator and mount it to the new one, as the new one did not come with a resistor.

I installed the actuator and started the car and all the lights were out. I cleared the codes and went for a drive and the car seemed to run great, maybe even shifting a little smoother than before.

I've gone on a few short drives with no oddities so I am hoping my issues are resolved. I plan on draining the t-case fluid and replacing it then heading to an indy to get my adaptations reset.

I will let you guys know if the I find myself the way of DMF but I am hoping after 161k miles my actuator motor just kind of crapped out.

Next up replacing brakes and rotors and trying to figure out what is going on with my RPMs dropping by 100 RPMs here and there during stops. I am thinking VANOS solenoids..

Swamp, that's a great idea. I have attempted to get the cable and install the software before and gave up. It's funny because I am a software engineer by career, but it's hard to piece together requirements and versions and downloads and then troubleshooting.

Is the cable ****ty because I bought it for $10 off Amazon? Is the software not right because I downloaded it illegally as a torrent? Is it because I am on a 64-bit Windows? I just gave up because it seems like it's kind of black market equipment with vague instructions, and a lot of it is in German. I also don't understand the difference between DIS, EDIBAS, and the other several softwares in the suite.

If you have a write-up that you think is accurate I'd love to try to get my laptop setup again. The other caveat is that the only laptop I own is a Mac. I can run Windows in bootcamp or as a VM but I wasn't sure if the Mac itself made things more difficult.

Thanks for any input!

never ever ever give up on software etc !

>link for rheingold and other software

http://www.bimmerfest.com/forums/sho...=1#post9972460

>link to request rheingold on this FEST

Here is the message that has just been posted:
***************
You have to post a reply in that thread asking for a link to rheingold. Then you'll receive a private message with the download link. It's all very spy hush hush mysterious. But the link and software are legitimate.

You'll also need a cable to connect your laptop to your car

Thanks a lot!

I will report back with success or failure on the software and keep anyone up to date on if the actuator was the solution or just a bandage.

One Last question

Why does this package come with 2 cables?

http://www.ebay.co.uk/itm/BMW-DIS-V4...-/191978604081

Do different softwares require different physical interfaces, or are the multiple cables to accommodate different era vehicles?


Answered my own question, emailed the vendor. He suggested http://cgi.ebay.co.uk/ws/eBayISAPI.d...e=STRK:MESE:IT based on my VIN.
