Yipee. After talking and begging and whining with BMW tirelessly, they have decided that they will "honor" my warranty for future parts and services if I tune back to stock and reinstall the cat. So I have to pay around 7 grand for the de-tune, cat install and new diff/ install.. which obviously sucks, but they say they will then honor the warranty for the remaining 4 years. And this offer is coming from an official BMW rep, I forget his exact title but he oversees all of Socal BMW dealerships. I'm trying to get as much on paper and written down as I can, but for the most part I'm just going to have to take their word for it. They know my car and situation now, they feel bad that all this falls into my lap and I'm honestly impressed with how they are dealing with the situation. I will be going to the original private BMW dealer (CA Beemers) later to have them take responsibility for as much of the costs as possible, but I have no idea how that will go. At this point, I'm just happy I'll get my car back in working order. And I'm glad the BMW rep is so understanding and willing to work with the situation in an honorable fashion. Wheeeew.. this has been interesting.

The reason they will " honor " the original warranty is because they are required to by federal law.

They are trying to make this sound like a favor but if they had any other position you should be calling the FBI.

Return your car to stock ( which is the way any person who really cares about their vehicle warranty should keep it ) , and sorry about the differential. I'm still not sure how it's been proven that the diff failure is from a tune and removing the catalytic converter, but it certainly seems possible that the prior owner may have damaged the car and knew it and dumped it before the problem got worse... and of course they dumped it by selling to a non BMW dealer so that the issue wouldn't immediately be known.

If you actually went and pursued the dealer legally this all might come out under discovery ... but that's a long and more expense path more than likely and I'm certainly not recommending it.

Yea that's exactly what happened

Is the dealer willing to tell you the launch control count? Not that it matters at this point but I'm betting it may be related more to excessive launches vs. a tune?

If they will accept it, it might be worth looking for a used cat from someone who installed a downpipe and also reselling the downpipe that's on the car.

Shame you inherited someone else problems.

This was a long time ago. For some reason backups didn't fix the issue. That's why I had to use my last resort and have the dealership deal with it.
