C1A20 Pressure Increase to Slow Filling Reservoir

C1122 Steering Isolation Valve


Cheers

C1A20 is a lack of air pressure when filling the reservoir

Either a worn compressor or leaking air tank are the most common issues

C1122 is a wiring issue to the valve in the steering rack. Guessing your power steering is fairly heavy most of the time?

C1A55 is usually an EPB related code, wiring issue in the NSR arch is the issue 99% of the time

Start by finding the broken wire, and either repair if possible, or overlay with new wiring
