2014 with 89k. Engine whines a bit. Thinking about getting timing chain done at 100k.

Hasn't needed much attention up until recently!

I have bit of 'whine' on my car when a/c turned on. I'll be curious to know what your Dealer says. I did DIY PM of my serpentine belt and tensioner/pulley a year ago; that had no effect on the whine I'm hearing.

Keep us posted!
Thanks/Bill
fyi...my car at 89K miles.

Dealer said it was low on freon, so they added freon and did an "a/c service" on it. Cost $192 (a/c service not covered by CPO wrap) and the noise is now as you describe yours... "bit of a whine". It's still there, but now it's off in the background and can't hear it over the radio like before.

Add me to the list for the A/C compressor "bit of a whine" albeit I have the N47. I'll have the A/C system checked before summer.

Dunno why 2014 below 40k miles just changed to my 3rd set of brakes, not an aggressive driver at all, F26

2016 49k miles. Still looks new. Rear brakes were replaced under free maintenance. Will replace front brakes on my own dime next week. Other than that have replaced tires. With working from home the miles aren’t adding up to fast. Can’t really justify a new car.

2014 28i original timming chain with 162k kms ( ~ 100k miles) . I am the second ( or third) owner. Having concern about the timming chain issue since the day I bought it but it is still running strong. Some mechanics from the independence garage told me my x3 having engine oil leak while maintaining my tranny, but I have never needed to top it up and I did check it myself, still no sign of leaking. Waiting for time ( and money) to swap Valve cover as well as the new timming chain at the same time ( in order to cut down some labor cost). Planning take a road trip soon but not sure the X3 can make it. Somebody says that mine is reaching the end of its life.

2013 X3 28i with 72k mi

Just did the timing and oil drive chains ~500mi ago. Engine had startup rattle. Found that timing guides were falling apart and had separated at the pivot point.
