I had called BMW a few months back before giving them my car to fix something. I asked the Service Adviser if coding the car was an issue with warranty or anything else.
He flat out said it has no effect what so ever on warranty or lease return, unless the coding affects something that gets messed up and even then the warranty will be void for that specific item only, very rare !!
