Been happening a few times lately and I had forgotten to post it up.
So as per the manual, pressing the DSC button lights up the Traction symbol on the dash. However, if you kept it held for over 3 seconds it lights a second lamp (for the braking system I think)
Anyway, lately I have tried it when I have just started the car, and I get the first symbol to light but not the second. I tried this when the car was moving the other day and the second light came on. Any ideas?
