I'm fine still. I peeked in there yesterday. Coolant exactly where I filled it a bit below half. 210 mile road trip to poconos, hills galore. No issues. Well except that my pass rear door wouldnt open. But thats a different story all together.

I just had the collapsible coolant pipe installed w/ new O-rings in my '08 4.8i X5.

Coolant was flushed and replaced with Pentosin NF.

I've read that it could be beneficial to switch the coolant cap to the BMW 1.4 Bar Cap used on the 2007 335i. Any reviews on this cap or suggestions for me? Would this 2007 335i cap fit on the '08 4.8i X5?

I changed mine over and have had no loss of coolant since. before I went through 2 coolant tank ruptures and had to top it off every 6 months.

I would suggest it to all N62 v8 owners.

Good to hear man.

So did you buy the 1.4 bar cap from the 335i? I want to be clear on the exact part that I should buy from the BMW dealership
