Change transfer case fluid, reset needed by BMW?

Gee3 · #1 10-19-2012, 11:44 PM

I changed my transfer case fluid on my 2004 X3 but the fault light keeps on coming on once in a while. It goes away for a while once I turn off the engine and restart it. But am I suppose to reset the transfer case/computer via the dealer?

Thanks in advance!

Yes, BMW call for a reset when the fluid is changed. If not the dealer, then someone with the appropriate computer tool.

Thanks JCL!

Anyone in San Francisco have the reset tool so I don't have to go to the dealer? I'll buy you the beer and lunch!

How much are dealers and independent mechanics charging for the computer reset? I called my local dealer and they said $180! WTH?!?

I don't know, but I would have hoped more like $100

There is a transfer case Reset? I have changed my transfer case twice as preventative maintenance and never knew that there is a reset procedure...

It's part of the DIS software; there's a service function which allows you to say that the transfer case oil has been changed.

Maybe I'll see if an independent shop can do it.

that light is an indication of an error in the system, the fluid wear values does not cause the light to come on.

I changed my transfer case oil around five months ago and has not reset anything. I hope it is not destroying anything. I thought as long as the oil is new the transfer case should be ok, but I might be wrong.

Also, the reset does not turn on any warning lights. It only activates an OBD code that say something about transfer case oil having excessive friction. I am sorry I cannot remember the exact wording now.

To be honest, I cannot imagine how anyone would know about this if they did not have a scanning device. I read mine because I have the Bavarian Technic device. I was resetting after an oil change and I noticed the warning. It even said the error would not cause a warning light to come on.

So, the question is: if the reset was so necessary, why doesn't it turn on a check engine light? What does the reset to anyway? Isn't the transfer case a stationary set of gears that transfers the vertical rotation to a horizontal one? What does the computer reset exactly?
