Any other traces of shavings, rust, or anything unusual in the rail and components?
If possible, I would temporarily revert back to stock. BMW engineering may look for tuning. The data readings are through their ISTA system and it's called FASTA data. I don't see how a dealer wouldn't have tools for that...
Hope it gets solved soon!
I'm curious to know the cause.
