Any idea, I went to start my impreza yesterday and the abs light didn't go out. It's still not working so i've booked it in to main dealer but what could this be and is it going to cost loads. Any ideas?

Its possably a sensor, they cost around 70 quid on average.

Took my car to chelmsford today and it's sorted free of charge. Mechanic seemed to know what it was straight away. Pluged in into computer and the abs connecter to the rear drivers side wheel had come undone. Apparently a common fault, as rear passengers constantly getting in and out loosens the joint. So he simply undone the rear seat and plugged in back in then reset the system, 5 minutes! Well chuffed!
