Yea pretty open shut case if they have a history of you being their and the oil they used as the tech usually makes notes and leaves a list of shop materials used. Their was an invoice made and charged out for whatever oil they gave you so you should have a record of that.
Once you show them the bad decisions that where made and they where the ones that made them then your all set to have them held responsible.
Also you may want to call BMW USA and file a report with them. I've had an issue with a dealer once that put an unrecommended additive in my oil to get rid of a ticking noise on my z4 as the N52 engine in 2006 had a design flaw and no check valve which caused a ticking,
Well their additive cause a slew of problems with the vanos system and BMW USA got the dealer to replace my head on my Z4 free of any cost.
So you never know.
