F15 35d // Build Thread

Does anyone have some feedback on higher mile F15/E70's? I have been looking around but wondering if there are any larger issues that these cars face down the road?
I know some of the general stuff like 3rd row cars with airbags, general N55 stuff, etc.
I am kind of in your same boat with looking at an E70, but also seeing some higher mileage F15's for similar costs. I like the E70, but the F15 takes a huge jump in the looks.
The Imperial Blue and the brown is a great combo.

I tried looking into this a lot given that my price range would be a higher mileage one. And I couldn’t really find any complaints of major issues other than the things you listed: n55 oil leaks, bags, and drivetrain servicing.
Having air bags was a huge concern for me, but it seems like they’re pretty reliable and if a bag leaks, they’re not that expensive and replacing them is a very quick job.
I have some slight shuddering/jerking as I coast to a stop. But I have everything coming to service the transmission, transfer case, and front diff. I’ve read of significant improvements in drivetrain feel after servicing everything. Also a new OBD tool that can reset adaptations.

I believe the X5 35i uses the N55. From my research + owning an N55 335 recently I'd say they are pretty stout into the higher mileage. Most of the issues involve the common oil leaks - valve cover, oil filter housing (can drip onto belt and be sucked into the motor if it slips off, real bad stuff), and oil pan gasket. N55s also use an inferior oil pan design than the N54 or the V2 N55 used in the M2s (https://www.2addicts.com/forums/showthread.php?t=1763724) where at high lateral Gs it can starve the motor of oil and run into rod bearing wear. Probably not super likely on a big X5 though...
Otherwise I've read the transfer cases and two diffs hold up pretty dang well! I'm planning on doing what I think is this X5s first fluid changes, so I can report back how that goes. Most of the F15 X5 issues seem to be with the 35d and it's silly emissions components.

Did you sell the e90 to glen yet lol

Lol! @Rekpoint would probably offer $4k with a straight face. For now I'm planning on keeping the E90 too and storing it over winter again this year. It's a fun little summer daily and can't bring myself to part with it.

He wouldn't let me take it for 4k cash. I just want to buy it so I can daily it in the winter like its meant to do.

X5 was on 145k with original drivetrain fluids, so with the help of @Rekpointwe changed oil, front diff, rear diff, and transfer case. Fluids actually looked surprisingly clean for the mileage, but nice little peace of mind.
Still have trans to do, but saved that for another day because it looks like a damn pain.

That transfer case was horrible to do.
I thought that one wasn’t bad. I bought a long piece of really flexible tubing for my fluid extractor so I could stuff it down the fill hole. Worked really well.

I think the worst part for us was just getting a tool on that fill plug. We had quite the interesting contraption to get it lol

Ohhh yeah. I bought the special wrench tool for those after reading about how tight it is. Which made it an entirely non-issue.

We used a hex socket, a wrench and another wrench for more leverage.
