Congratulation Wallyx5, on your milestone, can you please list some of the preventive maintanace on the x drive, diferentials, water pump, I have a 2006 with 72,000 miles, i;m dabating on changing the oils on the difertian and transmision, than you.

Mine does not have idrive, the 2001 did not have that option yet. I didn't do much to the fluids. I drian and re-filled the differential around 220,000 and drained and re-filled the transmission with new fluid, but I did not change the filter. It's up to you if you bought the 06 new and put the 72,000 miles on your self and you plan of keep the X for a long time then you may consider changing all the fluids and doing it on a regular maintenance schedule. But its really up to you.

Thank You

for the OP u said u drive urs like u stole it and made it to 300k???!!!.i drive mine like it cant go over 40mph with a 0-40time of 10 secs or something.nothing but problems but i insist on keeping just because its practically a vagina magnet.anywayz you really must of gotten lucky with your x5

nice wow

I am not sure if I got lucky or not, BMW builds amazing machines. I am stilling running and just passed the 309,000 and still driving her hard. She likes it and built to take it. The transmission finally died at 308,000 but I had it rebuilt and we are back at it. I want to see 400,000 out of the motor

Cost of rebuilt tranny?
 

I see that your tranny died at 308,000. What were the symptons. What did the rebuild entail and how much?
I'm at 255,000 and somewhat apprehensive that if the tranny goes I might just part it out.

My Indy pulled the tranny and I shipped it to a shop in Cali, Peter something I can't remember right now but they were excellent to work with. They rebuilt it and shipped it back for $ 2800.00. They offered a unlimited milage warranty for 2 years. My Indy charged $ 1000 or so. All in I spent around $ 3800. The X is now back on the road being abused and loving it.

transmission rebuilder
