Dinan (and others such as Hartge) will "match" the factory warranty , but you're still at the mercy of their willingness to help you. BMW will wash its hands in the event or a warranty issue. Dinan cars also get flagged in the dealer system (the VINs of modified Dinan cars are exchanged with BMW NA) to make sure the dealer is "aware" .
Other tunes/tuners are at the same risk , it just depends how hard your dealer is looking and which events the car/DME is logging . Once the car is connected to the diagnostic system there's a good chance the data is sent to BMW HQ and the dealer has no influence over what gets sent etc ...
