Transfer case actuator motor

[neilrmp]

hello, I am going to change the Transfer case actuator motor on my 2006 x5, I am familiar with the removing and re-installing of the unit but need more info on the repair" function done with GT1, I read that you need to delete the value of the classification resistor but don't know how it's done, any info will be appreciated.

new Motor should come with a new classification resister simply code the motor and transfer set the the new calibration via service functions

Thank you for your reply..

I have a 2005 BMW X3 with the Brake, 4x4 and ABS lights are on. When the vehicle is shut off the transfer case actuator clicks several times. The front wheels are currently not powered.

I can get the actuator for under $900 on the internet. A repair facility wants $1150 for the repair. It looks like an easy replacement. If I do it myself, how do I reset the resistance values to the new unit?

Thanks,
Jason

It is a easy job, just 4 bolts and two electrical connections, I didn't even have to lift my car, It worked without using GT1 but I activated it just to make sure.

neilrmp, if you don't mind, could you tell me why did you replaced the TC actuator? What were the symptoms? Did you get any fault codes?

TIA

I replaced the actuator motor because there is a plastic gear inside that was stripped, BMW would not sell the gear alone you have to buy the unit, the car can't activate AWD so it turns off the ABS DSC and 4x4, no codes are generated, but GT1 will will let you know it failed. The car goes into 100% rear wheel drive.

I had thie part replaced on my X about a year ago. I kinda wish now that the X had a switch/option where you could switch the power to be 100% at the rear only (for good weather condition driving of course) as I feel that would make the truck a lot of fun on a different level.
I pondered leaving the stepper motor broken for a few months, but it happen to GO in the middle of our winter here, and I bought the X to deal with the winter/snow here Glad I bought it though. Love the heck out of it. If it had of stopped in summer, there would be no way I'd fix it until winter. I'd love a rear wheel drive X5 (as long as no other systems were negatively affected * taking note of the ABS/DSC systems being deactivated)

Thanks, unfortunately that sounds like my problem.

there was an inexpensive alternative, take the stripped gear out and have it made, I was quoted $65 to $100 to do it. I don't know if it has ever done before but it is possible.
