Toyota Avensis 1.8 VVTI 2002 engine warning light came on after I stalled engine and has stayed on . I have been driving car for a few days with seemingly no difference in performance - car running same as usual. Batterry disconnected temporarily which stopped light coming on for a while but came on and stayed on again. I've booked car in for service and reading to be checked etc. but just wondered what could be causing this and if driving it in the meantime likely to cause any problems ?
Cheers for any advice
