What happens if I go for a dealer visit, and they flash the car's software? Will they have problems? Would I have to send in the DME to be unlocked again?

There's a few way to answer this. Going from Experience + a few personal friends (N55/S55/S63TU). Updating the car software is more likely when you haven't visited the dealer in a while or there's a new update to fix or improve something, having issues with Navigation/Electronics, or something else with the car. Typically, Dealer plugs it and see if there's any updates available. For the most part, you will not need to revisit for Unlock because they're updating another part of the ECU. Now, if you specifically have a major issue where the dealer needs to REPROGRAM/flash the car software your car then you will lose your tune but more than likely you will not lose the Unlock part.
