Check engine light on 2008 RS SE5

[Crisis]

Most times when I turn on the key before I start up the first time each day, the check engine light comes on. If I turn the key off and back on again the light disappears. Should I be concerned. Thanks

Either call up the fault code(s) when the light comes on, or have your dealer check with BUDS.

Mine did the same thing for over a year, Buds didn't show anything, finally the oil sensor starting leaking slightly and once I replaced it all was good.
