X-Drive Maintenance???
 

I was in the heavy maintenance mode with tranny, final drive, engine, waterpump, thermostat, coolant, brake fluid, power steering cycle. Of course I am doing one of these at a time to make sure that each job has been done correctly!

However, after changing smelly(especially the final drive) and dark fluids, I am thinking about the x-drive multi clutch disc system. Is there maintenance on it???? sound wierd if there is none~~

x-drive fluid check at inspection , change if discoloured .

the VTG sends a current signal through the oil to determine if the oil is worn out, this will set a fault in the VTG control unit, advising the tech to change the transfer case fluid. a GT-1 will be needed after the fluid exchange to re-adapt the new fluid and then to clear the fault memory.

What are you smoking? I had my x-drive t-case fluid drained and refilled. Nothing needs to be reset or re-adapt. No issues since 8K miles.

wow, such ignorance.

He didn't say that anything needed to be reset if you changed the fluid. He said that if the fluid needed changing based on a sensor indication, you would get a fault code and then you would need to reset it.

Personally I wouldn't want to debate it with a BMW tech (and I believe killcrap is one). I suspect he has probably done this procedure himself.

A bit rude I agree. Chill out. He's absolutely correct.

Here is a printout of the work order/invoice for such a change:

I can also second (or forth) his statement.

Sorry to create such a debate on my ignorance~ Just wondering~ anyone DIYed it?? I never seen it mentioned in the forum.

The drain and fill would be pretty straight forward, just a big allen wrench away!
