Need some advice from my fellow i5ers! Just diagnosed a bad E52 relay which seems to be part of the whole shift by wire system. Created a kill switch to test it (I'm safe!) and it basically cuts power to the car when flipped off. Here's my question: if the E52 dies while driving (like at 60mph on the highway!), what's the worst that could happen? I'm guessing the car would coast to a stop, but the diagrams are confusing. Anyone else have experience with a bad E52? Planning to test the kill switch at low speeds first, but curious to hear your thoughts!
