Would the DSC 'Inactive' light showing up sporadically and not being able to toggle it even with the warning light not being on be a sign of needing to be replaced? Something I've had since I bought the vehicle but never caused me any problems and accelerates fine most of the time.

Edit: As described in the video, the "trifecta" lights of all three coming on... thats what I meant. Not just the DSC Inactive, but it pops up before all three of the lights come on.

Since you have the non-xDrive transfer case (NV125 vs ATC500) you don't have this gear etc.

Also, the DSC warning wouldn't be related to the transfer case operation unless the transfer case was so compromised as to allow a speed difference between the front and rear drivelines.

From your other post about ATF on the ground, I'm guessing you may have a "compromised" transfer case - damaged chain or sprockets etc....

Ah okay, thank you for the clarification on that. Good thing I didn't order that gear already. :

I'll have to bite the bullet I guess and get INPA connected to it to try and find out where the warning lights are coming from. My SnapOn Computer doesn't show any information or codes stored for the lights coming on.

It was bought with 245k Miles with no service history so I should have expected something like this.

Good idea and should work. I will let you know how it goes.

Ive got to do this to the wife's 2005 x5 but Im going to replace the whole assembly this time. I will save the old assembly and order a gear for it and fix it and have it on hand if ever needed again. I figure with all the miles it has on it I will just replace the entire thing this time since I have read where people have had trouble with the plate when changing the gear.

Clicks at shutdown followed by trifecta today. What gear should I purchase (several are mentioned throughout this thread). Thanks to OP for this, his video and others for helpful comments which encourage me to dive in!

wow thanks for posting, when I first did this video there was no official repair kit (to my knowledge) from BMW. I wonder what date they first started offering it? The BMW dealer told my wife the repair would be a new transfer case for $4000+

First offered (I believe) sometime in 2017, but because our cars are soon going into the “classic” catalog, not a lot of BMW techs/parts guys working on/talking about them nowadays

That makes sense. BMW looked at the X5 in December 2015 and that is when we got the "it needs a transfer case, we can do it for $4000" line from them.

Anyway that kit looks well worth the money for the extra parts and cover that does not come with the gear sold on amazon
