Think I found the reason for my erratic voltage - I tested the compressor which works fine so I made a new plug and will be refitting tomorrow - hopefully the end of my suspension head ache

thanks for taking the time to respond Gareth. I am doing more troubleshooting today but cant stop thinking that the erratic voltage to the solenoid block may be the cause of my issues. What I noticed yesterday was......clear the codes and the solenoid reads 12v....start the car it gives an "Car too low - controlling level" (still 12v going to solenoid) then a few warning lights "Air Suspension fault - max speed 35mph) at that point the voltage reading to the solenoid goes crazy I'm spending some time today on the compressor - wish me luck 😂

Fault codes C104600 (level control system) & 00471 Electronic Damping Control Module I recently carried a heavy load of wood in my RS6 C7 and since then have had some suspension problems, I'm getting codes C104600 Level Control System & 00471 Electronic Damping Control Module. I've been trouble shooting / reading / watching / scanning and researching for a few days and have a few questions regarding my findings. I bought an OBDEleven and when looking at the live data in the "Chassis Control" module I can see erratic voltage (from 0 - 14v) at the Solen.Valve.Block and I am wondering if this means the block is at fault or the control unit supplying volts to the block? I am trying to rule out which component(s) are at fault - a common fault is the air compressor but I get no codes relating to over heating or cut offs so I am assuming this would show in the scan? I've also checked all 4 corners and can verify the level sensors are not seized / broken Any help / advice would be really appreciated
