Yeah, found it isn't anything out of the ordinary. However, disconnected the battery and engine light went off and hasn't come back on yet. Mind you it's only been on a 30 min drive!
Hope it stays off but will no doubt return at some point I'm sure.
I'm not sure I agree about the black alloys - I think the black on black looks fine (it is an improvement on how they looked when I got the car) but I will admit it would look a lot better with the original alloys on!
