Driving my 07 R56 S the other day and it just died, the engine that is. Wont start now. No fault codes. 2 pending codes for air intake sensors. Throttle body makes squealing and clicking noises when ignition is on. Engine cranks, fuel is coming out of HP side of pump and I have voltage at the coils. Could the throttle body have conked out or is there a more obvious explanation?
