2006 325xi Transfer Case Motor/Gear

I have read dozens of threads and only find answers to the X3 and X5. I have the same symptoms as described, but can't find the answer I hope exists for my daughter's car.

The trio of lights came on- ABS, 4X4 and Brake. I figured a sensor. As I was diagnosing it, for the first time I heard a "click click click" noise when I shut the engine off. It almost sounded like the noise when setting an emergency brake. But the emergency brake did not have anything to do with - just comparing the sound. So I came on here and read for a few hours different ideas and suggestions. Well, it seems to be the transfer case motor has a stripped (or worn down) gear. The X5 adn X3 forums have great detail, pictures, and solutions. But I can't assume these are the same parts. I went to several sites that sell the stripped gear, but they are NOT compatible to the 325XI 2006-newer.

I find the entire motor for $400+. The gear for the X5/X3 range from $10-100. Brass, metal, plastic, etc. No gear/cog, whatever you want to call it for the 325XI.

Does anyone have any ideas or suggestions? Does anyone know if the motor is similar so I could pull it off, remove the cover, and turn the gear 180 degrees to get the other side used?

Thanks. First time poster....6 month reader of this forum. Only BMW I have owned, and it was for my daughter for Christmas.

Also thanks to this forum...I replaced a window motor and door lock actuator with the help of people on here.

RealOEM.com. Enter with your VIN-7 and search / drill to the part.

Maybe this one

Thanks Doug. They have just the motor on the parts list, not the gear. And it is $770! crazy expensive. Thanks again for the reply.

I did the motor on one maybe 4 years ago - was about 400 bucks at the dealer for the motor - took the old one apart and was the worm gear in the one I had that wore out, basically the threads in the middle of the gear where done, ends were ok - this may do the trick for you if it is that gear

If you want to be sure pull it out and take it apart to see if it is the worm gear that is done.

Mein Auto:
I found a new motor for $170 from wholesalepartsexpress.com
Part #27107546671

It didnt fix my problems, I still have the triad of lights pointing to the passenger rear sensor. I've replaced the sensor, the bearing, and the axle before swapping this actuator motor.

Now it seems that my car is always in AWD, it has become sluggish in low speed turns and appears to dissengage from AWD after I shut the motor off, letting out a good size clunk while rocking the car.

You will not be able to do the X3 gear, or the swap trick. Our gear is metal instead of plastic, and when I dissasembled mine, it appears to use the entire length of the gear, mine was concaved 100% of the circumferance.
