Similar issue
Subscribing to this thread because I am getting a similar issue.
A slight tugging or skipping sensation, fells almost like "wheel hop". NOTE: I started to notice mine recently right after i replaced the OEM 19's with 20" BBS SX's wrapped with Conti Sport Run Flat's. I am wondering if these wheels could be the cause of the issue or the issue themselves. |

tugging/ jerking
I had the same tugging and jerking on my 2014 BMW X5xdrive 501 F15 at 60k. Took it to dealer and they told me I need a new transfer case, the bill was like $7,300. Went to my local guy and they performed a transfer case service/change fluids/reset computer for $150. No issues since. now almost at 80k.

I had a similar issue however I got a drivetrain error.
The first time I took it to the dealer they said they couldn't replicate the issue. Error codes showed one misfire. Of course it happened on my drive home so I took it back. They eventually diagnosed it as a bad coil, replaced it and I haven't had any issues since. |

I had this problem last summer - ended up being a bad coil that was replaced under warranty. Fast forward to this year, and my X5 50i started doing it again - felt like a misfire under heavy acceleration. Took the dealer a while to figure it out this time (no codes), but it ended up being a vacuum leak caused by cracked crankcase ventilation hoses (the plastic ones that get brittle and crack from the heat of the turbos). Replaced with the updated silicone parts (again under warranty), and it's back to running strong.

My 4yr/50k expired 3 days ago. Dealer has been trying to solve this issue for the better part of the past month, so I'm not worried about them taking care of it, plus I have another year of CPO coverage. I suppose if the engine is going to go, it might as well be now. But, my guess is that it's far less severe than that.

Picked it back up today after they replaced coils and plugs. No sign of the misfire problem on the drive home, and I had a chance to get in some quality "spirited" driving. Feels strong - faster than I remember it. Not ready to call it cured just yet, but cautiously optimistic.

2015 BMW X5 x3.5i 70k miles; offset wheels
Posting my results as this thread saved me $5,000!!! Summary: Problem: Car started showing signs of a very subtle shudder/stutter/skipping sensation. A little like tires out of balance or driving on ripply pavement. Resolution: Transfer case issue; I used ISTA+ to do a "Transfer box (VTG): Calibration" , then replaced transfer case fluid and recalibrated again and problem was resolved and has remained resolved for over 5 months. Details: Car was running fine for a few years. Front tires getting worn so we only replaced them with new Desert Hawk of the correct factor size. I say "Desert Hawk" b/c I had read where someone else started having this issue after installing those tires. I honestly don't think the brand of tire had anything to do with causing the problem - but rather the car seeing a sudden and dramatic change in tire size and that threw off the calibration of the transfer case clutch. Once we started having the problem, I went ahead and replaced the rear tires also - and that did not change the problem. Then I started diagnosing... No light. No codes being thrown. Problem occurred during acceleration, whether light, moderate or heavy. Problem was intermittent. Took to a local independent BMW shop in Lawrenceville GA and they diagnosed the problem as clutch wear in transfer case. They said part is not serviceable. A new transfer case w/ labor was about $5,000 to replace. Took to another independent BMW shop in Suwanee GA and they diagnosed the problem as tires out of balance. They balanced - but we still noticed the issue. I discovered the wealth of information here and decided to go at it on my own. I first disconnected the transfer case fuse. For the BMW X5 F10 "Transfer Box (VTG)" Case Fuse is in the passenger wheel well. Fuse #63, 30amp. I pulled the fuse and went for a test ride. Instrument cluster will report "Chassis stabilization: Drive moderately" with the picture of the car swerving (which is how I drive anyway). I test drive showed the problem was GONE!. Okay - so now I know it is related to the transfer case. I have read where people actually unplug the transfer case from under the car. Pulling the fuse seems way easier. I have also read that driving around w/o the transfer case is bad and perfectly fine. I tend to think it is perfectly fine. The hardest part of the repair was the next step, downloading, installing and gettin to run the ISTA+ software. Search the forums here and everywhere else and just keep installing the dependent packages and it should eventually work. I thought I was being smart and only installed the latest of say some MSFT VC++ Redistributable. Nope ... need to install them all. I bought the Enet cable needed on Amazon for $18. I bought a "Enet OBD2 Cable,Ethernet OBDII RJ45 Car Diagnostic F-Series Scanner" For the fluid, again Amazon for $40: Rock Oil TF-0870 IYK500010 Full Synthetic Transfer Case Fluid (1 Liter) for Land Rover LR3, LR4, Range Rover Full Size, and Sport/Sport Supercharged Once I had the ISTA+ working and ready to do the fluid change, I decided to run ISTA+ and recalibrate before and after changing the fluid. My thinking is that either the fluid change or the re-calibration is likely all that is needed. Not both. But because I didn't test drive the car after the 1st recalibration - but before the fluid change - I really don't know which one did the trick. To go off on a tangent - what I think happens is the car saw the initial front tire change as a "problem" and decided to fix it with a recalibration and that actually caused the problem. I have no idea why the car doesn't do a recalibration of the transfer case every month or so. Sometimes I think this car is "book smart" - but not real world smart. If someone else does this in the future - it would be good to just either change the fluid or do the recalibration ... but not both and see what fixes the problem. On the first recalibration, before the fluid change, ISTA+ reported: "Calibration value after the calibration: 22.2 degrees; Difference compared to the previous calibration value: -0.4 degrees" I jacked up the car and used the tricks noted here (14mm hex inside a wrench) to remove fill plug on transfer case. I didn't have to remove anything else (heat shielding, brackets, etc). I took some stiff tubing I had used for the refrigerator ice make supply line, heated it to create a little hook shape. I was going to use a vacuum pump to pull out he liquid, but since I had gravity on my side, a little syphon on the tubing to get fluid over the hump and gravity did the rest. It took about 15mins to pull out as much as I could I got 600ml, Used fluid was dark - but I didn't see any gremlins in it. I pumped new fluid in until it overflowed out the fill hole. Tightened plug. The did another recalibration with ISTA+. On the second recalibration, the system reported the same 22.2 degrees and 0.0 degrees of difference. So the new fluid didn't seem to require a recalibration. That was it. Since then it has never exhibited the shudder again. I guess I'll plan to do this after another 70k miles. |

Also curious about the fuse vice unplugging. Assume even if unplugged you get the same chassis unstable warning. I got 3 weeks until my appointment and want to pull this fuse until then but also don't want the dealer to throw some garbage at me saying I caused some future issue by doing this.

Found this fuse box diagram just for anyone else looking to do this. Interestingly enough my box wasn't exact but still easy enough to line up which is which.
