I'm not saying thats what you did - I am just saying thats how old turbos would die. This is why I like to change my engine oil frequently and sooner than BMW says too.
I know BMW changed the wastegate shaft(size) on the later built cars (~2009 or so) onwards builds. Maybe they also changed the turbine's bearing size too. ?
I find it very odd that your turbo failed while at your indi shop. Maybe they drove your car kind of hard on a test drive?
You can buy a new turbo from any of the forum sponsors here for about ~ $600 each. Good luck with the repair.

As always valuable info Dack, honestly I just shut the car off directly guess I would need to change that habit. I was there with tech the whole time he was changing the oil, they didn't even drive the car.
I think what happened is during my injectors issue only once I had a lot of white smoke on cold start up. Then after I replaced the injectors it was all good, so didn't think anything of it. I one issue was hidden under the other in a sort of way. I got a hold of a used one of a guy who swapped his for RB (has 50K km or so on it) for 350$. If this one has issues will get one of the sponsors and it would still be cheaper than the dealer (for both used and remanufactured).
I really hope this would be the end things breaking in the car and I can go back to enjoying it.
