      Does the motor have to be coded (at dealership, or elsewhere) after replacement? Doesn't the system need to know the new initial position of the motor, etc.

      Go get the code removed and see if they stay off. Have you ever had an oil change light on and had to get the clerk to remove it after they've fixed it? And if the light come back on then your initial problem remain from maybe an error during your fix

      You guys are amazing, thanks for sharing how to do this repair. I’m buying a used 1st generation X3 and will keep this tutorial handy as well as a spare servo gear in case I need to replace it on my car I’m buying.
      Thumbs up and thanks again!!!

      Good video, in reality there are some challenges. I just did this: to make your life easier, remove the 13 mm cross member bolts but not the 18 mm - hard to reach. The cross member will flop around enough to allow access. Lower the transfer case a little, makes the top servo motor bolts much easier to access. Use 1/4 inch socket/torx and you'll be okay. The other challenge is removing the housing on the motor itself. Patience is key. Eventually it will come off. When I tried to remove the gear, it wasn't that willing, had to rotate and pull from underneath with a pick; eventually it came apart. Hope this helps!

      You don't need to remove the motor assembly from the mounting. And don't forget to clean  the inside and put a new grease to lubricate the shaft and the gear. Second the rotation of the  motor is not 360 degrees therefore you can still use the old one,  just put the good gear side to the shaft and like brand new again.

      You dont need to take out motor long screw, just pull the gear out and put new one.

      My plastic gear is in perfect shape even after 115k but I'm questioning the servo motor itself...it's wobbly within the case and clicks when I turn it. I'd assume it's supposed to turn smoothly like a brushless motor?

      Excellent how to video. Thanks Bentley for making it available! I had to do this after a scenario where I had a tire replaced under warranty. You can't get away with single tire replacement on these newer AWD cars. It drove around like an old school 4x4 truck with the hubs locked up on dry pavement.

      In this video they show them removing the cross member bolts prior to the 18mm "through bolt". Do yourself a favor and remove the 18mm bolt first *after* supporting the transfer case. You'll find a sweet spot where the weight of the xfer case is supported, but the chassis isn't being lifted. By doing this you won't have the resistance of the cross member's weight or the xfer case pulling up. A wobble ended extension is highly recommended.

      So my ABS, BRAKE, 4x4 are on I pulled the servo motor off and the gear wasn't bad at all. I replaced the gear anyway. But the light are still on. And the 4x4 is still not working. Any suggestion. Please help.

      Great overview of the procedure. Was able to complete in 2 hours with the following additional considerations:
      1) Couldn't get the top bolt on the actuator gearcase mount with just the torx socket and a U-joint( the one mentioned as the most difficult). Here's what I did:
      a) Disassemble a 3/8 U-joint by using a drift or a punch to knock out the pins. You want the square pin in the center
      b) place some paper in the socket to prevent the square pin from going all the way into the socket
      c) use the 10mm wrench on the section of the square pin to loosen the bolt (you can turn it out the rest of the way with your hand
      2) Couldn't seem to pry the cover off the gearbox with small screwdrivers, picks, chisels, sharpened screwdrivers
      a) I drilled a small hole in the cover of the plate near the corner - enough for a curved pick to turn sideways
      b) placed the shaft of the pick in a vise, with the gearbox above the vise.
      c) used a prybar to apply upward force to the chassis of the gearbox, away from the mating surface...
      d) I applied heavy grease to seal the hole. I hope it is sufficient

      HTH!

      Do I have to buy the pre-determined tires, because of broken transfer case, etc.?

      I just replace my gear with a new carbon fiber composite - previous owner of my X3 had somebody replace the gear with a metal one which failed ! These knockoffs do not have the same gear profile which is critical !

      Hi,
      I'm having the same problem with my 07-525xi E60, I replaced the transfer case actuator motor and the abs, DSC and awd seem to work, but the 4x4 and dsc warning lights are still on, the car drives ok, but if I push the gas it starts to jerk/shake and engine light comes on until I restart the engine again, with Autel al419 scanning tool I only have a cyl6 misfire, but the engine runs good unless, like I said, I push on the gas, other than that I don't see any other faulty code for the transfer case, and even if I reset the codes the 4x4 and dsc light still on. Please help, do I need to re-code, re-program the resistor, ECM or something? Can I do that myself, or Where can I do that if that's the case, I live in Toronto Canada.
      Thank you
