X3 "Servomotor" replacement / Reprogramming HELP!!!

Hi everyone new guy here needing help. (Lots of it)

I have a 2005 X3 E83 2.0 Diesel, I live in a small Island in the North Atlantic in the Azores archipelago and, guess what! there are no official BMW shops or specialists of any kind in all the Island! And the worst is that the local shops with I usually manage to get my car fixed are not being able to solve the problem this time.

So, here is the description of the problem:
Few months ago I started to have this lights (ABS, 4x4, and Brake). First they appeared once in awhile and I didn't noticed anything when driving. But after a while they stayed permanent and the steering wheel became very hard and it doesn't turn back to the center if you leave it the car keeps turning continuously.

I went to the best equipped shop around. They called the BMW official mechanic in the mainland and were told that most likely it was a "Servomotor" that was broken.
(I donīt know if the name in english is the same but you can see the part on this link, its the number 12 of this diagram) Part number 27107566296.

http://www.realoem.com/bmw/showparts...27&fg=15&hl=33

We ordered a new "servomotor" and installed it on the car. It all remained the same!
So we called the BMW official again. They said that after installing the new one the car had to be reprogramed so it would function properly. Here is another big problem for me!
The local shop donīt have a BMW computer. They have a multi brand one that seems to work for everybody except for me.

Their Computer brand is "Brain Bee" The local shop called the computer representatives in Portugal and they said that they never had a situation like this with a BMW X3 so they could no help because despite the computer being able to reprogram manually, they don't know the numbers to do so. They tried to obtain that information with no success.
The car is stooped for more then a month now.

If anyone could give me a hand here it would be very appreciated, Anything about the computer programming or the servomotor, anything at all that you think can help to solve this problem is very welcome.

Thanks in advance guys
sorry for the long post and for my english.

All the best!
Henrique Mariante

Hmmm.

Well, the servo motor is the correct thing to replace to fix that. Hopefully someone here can tell you how to get that thing programmed.

X3 "Servomotor" replacement / Reprogramming HELP!!!

Review the thread called transfer case actuator potential free fix. It is a stickie and should be at the top of this forum.

I haven't had this issue my self, but did you try turning the steering wheel all the way left and then all the way right?

Yes I even used the car for several days after the changed the servo motor, But it all stayed the same. No improvements at all. I already saw that post and I saw some videos on youtube and one thing I'm wondering is that nobody mentioned the need of programming the car again. They just changed the part and move on. I wonder why they are saying mine has to be reprogrammed and why the new servo motor didn't solved the problem by itself?
Another thing i'm thinking is that nobody mentioned the same symptoms I have, the very heavy steering wheel that doesn't come back to the center position if you leave it.
Is it really possible that the servo motor is causing all this? or I probably have more than one problem to solve? I'm going crazy with this!!!!

Hmmm.... That sounds like something in your steering has failed, what does it sound like when you turn the wheel?

I think you have two separate problems. I don't see how the transfer case would affect the steering.

Basic question: have the triad of lights gone out after the servo motor was changed?

Captain Obvious question: your power steering fluid level is OK?

It doesn't make any sound when I turn the wheel, its just extremely heavy and doesn't turn totally back to the center when you leave it. If you take your hands off it the car keeps turning.
No, the light didn't gone out. When I first used the car after the servo motor was installed the lights were off for some minutes and then came back on.
Regarding the steering fluid level, to be honest I have no idea, I'm gonna pass by the shop tomorrow and ask the guys about this, and post here later.

Thanks for trying to help guys really appreciate it.

Wish I could help you Mariante. Have you tried calling a shop on the mainland yourself and explaining the problem?

If the car is not moving, does the steering get any better or worse? Is it still heavy?

My wife was just telling me she'd love to go to the Azores. Maybe I need to go see your car in person.

Same issue

Hello. I had the same issue around 86K miles. Got the servo actuator of transfer case replaced in a local BMW specialist. He had to re program the movements of actuator for proper operation via GT1 software. This is required to teach the transfer case for friction clutches' parameters. This reset - teaching function may be a built in function in one of those inexpensive BMW software that is available on the internet for purchasing and downloading. I have no idea but I am sure lots of people on this forum have many of these software pieces and can answer the question. This reset is required even after transfer case oil replacement. You will see the improvement on drive quality, especially on rain and snow.

Mariante,

I've had my transfer case actuator plastic gear replaced recently and it fixes the warning light issue immediately. Although I've noticed the 4X4 light doesn't flash anymore when the car goes through slippery surface, I'm not sure if it will need a alignment or the car before never worked properly.

In your situation, I would do the simple things first:

* check the two connectors on the actuator to see if they are latched in properly, the locking are slightly different.
* Open the old actuator gear box to see if the plastic gear has been shaved. If not, actuator may not be the fault.
* Having seen on the other thread some people have fuse issue at the back near the battery
* Don't get mind bolted down on the actuator has to be reprogrammed, if you go through the forums the majority of people who have this 4X4 warning issue all replace the gear or actuator themselves, no programming.

I hope this can provide some relief.

Hello everyone,
I'm new to the forum but was very intrigued by what 'Enjoydriving' posted concerning the servomotor.
Seems to imply that sometimes the entire part may not be faulty requiring only to replace the plastic gear part.
That would save alot of money.
Anyone thats had this experience before?
