2011 RRS. I'm getting intermittent C1A13-64(AF) RLM Suspension fault. A search from this site suggests replacing the suspension compressor valve. Does anyone know where I can find a replacement and where it is located on the vehicle. I do know the compressor is in front of the rear driver wheel well but didn't anything about the valve in the video I found on Youtube. I have found the part for 06-09 but not for 2011. Any help appreciated.
