I have a similar problem with the hicas light. except my eventually goes away. I reckon it's a problem with the power steering but i'm not too sure.
I used to have a starting problem (the car would idle really low and struggle to get to 1000rpm). I changed my fuel pump and the problem seems to have disappeared.
I reset my ECU on the weekend but I'm not sure if that's changed anything. (disconnect battery, press the brake down for a few seconds, reconnect the battery).
