It's not uncommon. The engines that last that long were the ones built on the looser end of the tolerance spectrum. But it sounds like the bearing failure demons still caught up to the OP.
This is guaranteed: If you hear knock, the crank is already toast. The more you run it the more likely you'll ruin the block too...And then you're really done. At this point from a financial standpoint you'll be better off with a replacement used engine. The chassis value won't support forking out big dollars for a new/rebuilt engine. You should do the RB service to the replacement motor before installing, don't make the same mistake twice. The VANOS code is likely due to bearing debris having made its way into that system and blocking its operation. Common for engines with failed bearings.
I would take it to an M3 specialist. Probably will need to have them drop the pan- it's the only way to verify.
