Hi, 2003, 2.0t Vector, 59,000 or so miles has just started to display an engine warning light has come up on the dash, however there is no error message and the start up checks come back 'OK'. There is no appreciable difference in performance and I have put the fuel cap on and off a few times (as I understand that may have caused it). Apart from the 'usual' rattles and strange noises, it is a Saab after all, nothing else I can think of to mention.
Can anyone suggest an explanation for this. Especially if it is an easy check / fix
Thanks in advance. Optimus
