I have a fault reading from my GS911 which reads " Balance pipe valve servomotor, no feedback or adjustment error fault is currently present 21FA31 fault occurred 255 times. What does this mean re a part that is no longer working or ECU problem. I have 14 days remaining on my warranty and the nearest dealer is 375 miles away. I am in the dead of winter 0 F or approx minus 15 celcius. Is this a warranty item? I appreciate any input.
