Over the last few days, I have had a series of warnings which started with a yellow Air Suspension Fault and various related things, like the ACC and Brake Guard disabled. I had just completed a rather wet long distance drive and put it down to water in the electrics somewhere.
The next day, the red Air Suspension Warning came on and I could hear the car rubbing its wheels in the arches. I have a CETE module and have managed to lift the car up again, but the amber fault keeps coming back. The CETE module is in bypass mode, so I don't believe that it is causing the issue.
A VCDS scan reveals the following, which suggests a mechanical sensor fault. It is likely to be water in the plug (and how easy is it to check?), or is it more likely to be an actual faulty sensor? It's booked in with my local independent on Monday, but I'd like to have a tinker myself, if I can.
