If I remember correctly BMW checks for other parameters other than just checking your ECU for a tune so removing it before you take it in isn't really going to do anything for you. I also believe that it auto flags now if they plug it into the system. That being said I have been able to get serviced from a BMW dealership just have to remind them not to plug it in or update anything. I have had some dealerships threaten to flag my car over its mods so finding a good SA is important. I also have the Geico MBI to cover any accidents that BMW won't cover. I think there's a limit to most mechanical insurances on when you can add it so I'd look into that.
