Noticed when starting the car up the other day after it had been raining that the CEL would come on for all of about half a second, but then it just FADES out. Doesn't just pop straight off, but fades. ECU shows no codes in diagnostics mode, no difference to the way the car drives/boosts. Seems to happen a few seconds after the car is started and i've had a couple of fast flicks when going over rough roads. Kinda thinking it could be a loose or wet connector somewhere but not sure.
Youtube video uploading now to show you what i mean.
EDIT: Here is the YouTube video.
