Hi


Today i had a look at the connectors as you suggested. They were all connected firmly with no issues.


I also cleaned the actuator motor connectors using contact cleaner.


Once again, no improvements at all and i am not getting the dashboard lights constantly, previously they would not come on most of the time, now they are on all the time.


So, i think that my Transfer case motor, although it is new may need to be replaced.


Just a quick question regarding the transfer case motor. When buying from ebay would you rather buy a used motor or a new one? I know that this sounds silly but the last motor that i purchased from ebay was a new motor and that seens like it has failed on me.


Thank you

New ≠ fixed you have to follow the symptoms.

New chinesisum not any better than used working. Especially if you can rewind the miles clock.

I have checked and the symptoms point to the motor not working. The transfer case is not making any noises being idle or whilst driving.


I will be further investigating these issues before i spend money on a new motor etc.


Thanks

My scanner can abdicate the TC clutch motor.

The error says can't communicate so i think it's just deactivated you can try to clear codes with the engine off then remove the key and put the ignition on but but not start then see if cider comes back but listen for the motor.

Just to give you an update on my work on the X5.


I feel that the actuator motor that i purchased from Ebay is faulty so i may order a new one and hope that will help fix matters.


Also, today i had a look athe fault codes and these are the results:


1) 4F7a - EGS
2) 54C4 - VTG Calibration faulty. ***
3) 5F39 - ABS / DSC Actuator Motor
4) BD - Instrument Cluster..??




1) So, I have had a look at the EGS ECU and that seems okay, as in there is no corrision on the contacts, dry etc. But, i have ordered a working one just to test and remove this error code.


2) VTG Calibration.... I am not too sure about this one. I was under the impression that you can install the Actuator motor and then the transfer case does the rest.
Is there a calibration process that needs to be done on the car after installing a new Actuator motor?


3) There is a good posibility that the actuator motor may be at fault.
Now, i have removed the actuator motor and started the engine. When the engine was switched off the actuator motor gear did turn and then stop.


4) BD.... not sure what that is all about regarding the Instrument cluster??


Also, the software that i am using is DIS and INPA... i feel that they may be limited in what they can do.
Over the weekend i will install ISTA+ on my laptop... hopefully the download that i have is a working one.


I will update this thread and let you know the joys i come up against.


Fingers crossed and pray to all the BMW X5 gods that i can fix my car...lol !

Some TC have a special calibration resistor needs to be the right one

Yes you are right. The TC Actuator motor is paired with that resistor. In my case the TC Actuator motor already came with the correct resistor.


We are talking about the same resistor that is screwed on to the TC Actuator motor?


Thanks

Yeah that's the one. I think it's to calibrate the TC to the car so I don't know the magic of what makes that golden.

I think [mention]EODguy [/mention] went though that

Thank you... i will speak to EODguy too.


:iagree:

BD = brake-force distrubution - this is possibly a "phantom" error and many (most) e53s have this error. You can ignore it.

ITSA+ is different from INPA and DIS (newer) but won't offer any much in the way of additional "tools". Some find it it easier to use though.
