Don't get it fixed at BMW. Find a transmission speciality mechanic - does not have to be an Indy.

This is why I would always avoid xdrive

Mein Auto: 328xi server motor leak
2011 BMW 328xi server motor actuator leaking

thanks for the advice. Is this a common problem with this model . It has 75,000 miles.
I took it to a repair shop and he said he does not have the computer software to service this problem . Also Dealer said this is where the leak is coming from -server motor actuator. But what about the transfer case ? If it is the motor , can this be fixed.

Thanks

You need a BMW Indy shop not a generic mechanic.

What is a fair price to replace the Server motor actuator?

An indy or a shop specializing in transmissions, AWD systems, transfer cases would be just fine.

Did the Dealer show you the leak? I suppose these days that's a silly question

My Bentley Manual is very sketchy on the Transfer Case, but from looking at the Online Parts Manual, it would appear that the motor does NOT have anything inside it that would leak. Perhaps however the motor reduction gear case is lubed by transfer case fluid? The motor has an O-ring (27107548348 -- $8 part -- even from BMW dealer). That O-ring seals the orifice where the motor drive gear is inserted into the transfer case. See Item 14 in the diagram linked below. That COULD be the source of the leak.

Here's the parts Manual Page:
http://www.realoem.com/bmw/enUS/show...diagId=27_0032

If the X Drive is working OK all you may need is a replacement o-ring (several in diagram), seal or gasket (which you or any decent mechanic/tech could quite possible fix).

(1) determine & obtain the correct fluid for the transfer case & top it up (to just running out of fill hole with vehicle level).
(2) thoroughly clean the exterior of the transfer case, particularly around the motor attachment & leave any bottom shield off for ~ a week.
(3) when you park the vehicle, leave a piece of clean cardboard under the transfer case,
(4) check the cardboard for drips ~ 30 minutes after shutdown after car was driven at least 20 minutes (fluid is hotter, less viscous (thinner) and more likely to drip after longer run).
(5) Mark, as accurately as you are able, the point of the chassis above the drip spot(s).
(6) Get the vehicle on a lift, ramps, etc. and inspect the marked area to determine the leak source.
(7) If you want to be high tech, put some UV dye in the transfer case (after asking the dealer if the dye is OK for the case seals, etc.) and use a blacklight and special glasses to see the leak, similar to coolant or refrigerant leak tracing.

If you're lucky, and it's just an o-ring, to have someone else do it shouldn't be more than 1 hour shop time & $8 part (genuine BMW). Or might just be the three flange screws that hold the pump (and compress the o-ring) to the case are loose. How well do you know/trust the Dealer?

Please let us know what you find,
George

The motor is a $770 item (although I'm sure you can it cheaper somewhere.) It's not a hard job, but there is a bit of programming to do after replacement.

Mein Auto: 328xi server motor leak
Server Motor

Thanks all for input. Brought the car to a mechanic yesterday to speak about the leak . He said it is probably the seal in the motor which is leaking . Three hour job at $150.00 an hour. My question is if the motor is defective and needs to be replaced what would the total cost be with labor. Also can an independent shop do the reprogramming of the system or must it go back to BMW .

Thanks

Indy with the right computer should be able to do it easily. Heck, *I* could do it with my BavarianTechnic cable and software.

Dude, in all honesty.

Have the shop just remove your transfer case and AWD components and make it essentially RWD. Your car would not have a single issue right now if it wasn't for xDrive.

Dud(e), HONESTLY:

RTFM, or at least look at the mechanical parts of the AWD system on RealOEM.com (the online BMW Parts Catalogue) and you will see how ridiculous that suggestion is. Then there is the electronic control matter, Stability Control -- what do you think that pump is attached to the transfer case to do -- turbocharge the front wheels? This is NOT a "dumb" system like the Jeep 4x4 systems of the 70s & 80s that you only engage on slippery surfaces, but rather an electronically controlled full-time AWD.

The OP's problem is a simple leak, probably an o-ring, gasket, or something loose; part cost <$10. There are only three (3) places I can think of that pump could leak from:

(1) The o-ring where the pump is mounted to the transfer case;
(2) The o-ring/seal/gasket where the pump electric motor is mounted to its reduction-gear case;
(3) A crack in the reduction-gear case or other opening in that case.

Obviously the transfer case has other seals & o-rings, so since we haven't examined it carefully, we don't even know WHERE the leak is originating. To properly diagnose a problem, one has to actually take the time to observe & think.

That's why the first line of my post to this thread (see above) was:
Did the Dealer show you the leak? I suppose these days that's a silly question

I have 138,000 miles on mine and the only major issue I had was replacing the valve cover gasket, which has nothing to do with AWD! Bad advice Dude!

If I got quoted $1600 to fix a leak I would rip out the xDrive transfer case and never buy another xdrive vehicle again.

BTW... you don't get any DSC issues from removing DSC components. That's only if you pull the fuse.

Why do we need to program? Can't you just unplug the battery and work on it ?

The system needs to figure out where "neutral" is: it's an adaptation thing to initialize the position of the clutches and motor.
