Same thing happened to my F80 back in 2015 when they filled SAF-XJ+FM during the break-in service.
I would have never found the mistake had they not also broken multiple iDrive functionalities during the same service, prompting me to do a full verification run of everything they touched, including spending a week to learn how to re-flash the ECU myself.
My solution was simple: I have never again let any dealer touch any of my cars since that day. These days I rent a stall/lift in a DIY shop every 6 months and take care of my cars myself.
I was wondering if I could potentially let them touch it for the 1200 mile service on my M2C, hence perusing this sub-forum. I got my answer, loudly and clearly.
