I have had the light pop up a few times when I have left the system activated on the Q4 and one wheel started to aquaplane. However its the control over the Q4 where you might not see the lights come up. Given that we have white water coming down again, find a large empty snow covered car park. Try some gentle and not-so-gentle manoeuvres with the ASR/VDC on and then off. You will feel the effect but experience no ASR/VDC warning lights come up until you get quite extreme.
At least that is what i experience with my fully working system
- V6 Q4 SW usually mud brown and not Titanium Grey (Spider S3 QV is Rosso Corsa)
